|Part of the Second Sino-Japanese War|
US Air Forces video: Flying Tigers Bite Back
The Second Sino-Japanese War began on 7 July 1937 with the Marco Polo Bridge Incident in the Republic of China. The war, by some seen as the start of World War II, ended when the Empire of Japan surrendered to the Allies in August 1945. By the end of July 1937, fighting had escalated into a full-scale war and both countries deployed their air forces, ground troops, and warships into combat. Japanese heavy bombers also extensively bombed Chinese factories, airfields and conducted the first major air-raids against civilian targets in the war.
The Second Sino-Japanese War was a military conflict fought primarily between the Republic of China and the Empire of Japan from July 7, 1937, to September 2, 1945. It began with the Marco Polo Bridge Incident in 1937 in which a dispute between Japanese and Chinese troops escalated into a battle.
The Marco Polo Bridge Incident, also known by Lugou Bridge Incident or Double-Seven Incident, was a battle between the Republic of China's National Revolutionary Army and the Imperial Japanese Army. It is widely considered to have been the start of the Second Sino-Japanese War (1937–1945).
The Republic of China (ROC), as a state in East Asia, controlled Chinese mainland between 1912 and 1949. The state was established in 1912 by Xinhai Revolution, which overthrew the Qing dynasty, the last imperial dynasty of China. Its government fled to Taipei in 1949 due to the Kuomintang's defeat in Chinese Civil War. The Republic of China's first president, Sun Yat-sen, served only briefly before handing over the position to Yuan Shikai, leader of the Beiyang Army. His party, then led by Song Jiaoren won the parliamentary election held in December 1912. Song Jiaoren was assassinated shortly after and the Beiyang Army led by Yuan Shikai maintained full control of the Beiyang government. Between late 1915 and early 1916, Yuan Shikai tried to reinstate the monarchy before abdicating due to popular unrest. After Yuan Shikai's death in 1916, members of cliques in the Beiyang Army claimed their autonomy and clashed with each other. During this period, the authority of the Beiyang government was weakened by a restoration of the Qing dynasty.
At the outset of war, China primarily relied on foreign countries for its military aircraft,but did produce about 100 Hawk II/III fighter-bombers at the Hangzhou-based CAMCO plant. 15 Chinese-American pilots formed the first unofficial volunteer group of pilots and joined front-line air units in China beginning as early as 1932 in anticipation of imminent war with Imperial Japan. These volunteers included future ace-fighter pilots Art Chin and John Wong. Both the Soviet Union and the United States came to China's aid by supplying aircraft and providing training to Chinese pilots. Volunteers from the United States and the Soviet Union participated in China's war against Japan, the best known in the West being the American Volunteer Group, better known as the Flying Tigers, which under General Chennault achieved considerable success against the Japanese from late 1941 to mid-1942.
A fighter-bomber is a fighter aircraft that has been modified, or used primarily, as a light bomber or attack aircraft. It differs from bomber and attack aircraft primarily in its origins, as a fighter that has been adapted into other roles, whereas bombers and attack aircraft are developed specifically for bombing and attack roles.
Hangzhou formerly romanized as Hangchow, is the capital and most populous city of Zhejiang Province in East China. It sits at the head of Hangzhou Bay, which separates Shanghai and Ningbo. Hangzhou grew to prominence as the southern terminus of the Grand Canal and has been one of the most renowned and prosperous cities in China for much of the last millennium. The city's West Lake, a UNESCO World Heritage site immediately west of the city, is among its best-known attractions. A study conducted by PwC and China Development Research Foundation saw Hangzhou ranked first among "Chinese Cities of Opportunity". Hangzhou is also considered a World City with a "Beta+" classification according to GaWC.
The Central Aircraft Manufacturing Company (CAMCO), also known as the Loiwing Factory (雷允飛機製造廠), was a Chinese aircraft manufacturer established by American entrepreneur William D. Pawley in the 1930s.
At the outbreak of the Sino-Japanese War/War of Resistance/WWII in July 1937, the Chinese Air Force had 645 combat aircraft, of which about 300 were fighter planes. Japan had 1,530 army and navy aircraft, of which about 400 were deployed in China.From 1941, many Chinese combat aircraft were US models, and the Chinese pilots were mostly trained by US or US trained aviators. Most of the Chinese fighter squadrons were equipped with the Curtiss BF2C Goshawk (Hawk III) and Curtiss F11C Goshawk (Hawk II), some were equipped with Boeing 281 P-26 Peashooter, British Gloster Gladiator and Italian Fiat CR.32. The air war in China had become a test area for the latest biplane fighter designs confronting the new generation of monoplane fighter and bomber aircraft designs; the world's first aerial combat and kills between modern monoplane fighter would occur in the skies of China.
The Republic of China Air Force is the military aviation branch of the Republic of China Armed Forces. The ROCAF's primary mission is the defense of the airspace over and around Taiwan. Priorities of the ROCAF include the development of long range reconnaissance and surveillance networks, integrating C4ISTAR systems to increase battle effectiveness, procuring counterstrike weapons, next generation fighters, and hardening airfields and other facilities to survive a surprise attack.
The Empire of Japan was the historical nation-state and great power that existed from the Meiji Restoration in 1868 to the enactment of the 1947 constitution of modern Japan.
The Curtiss F11C Goshawk was a 1930s United States naval biplane fighter aircraft that saw limited success but was part of a long line of Curtiss Hawk airplanes built by the Curtiss Aeroplane and Motor Company for the American military.
In August 1937 Claire Lee Chennault accepted the offer to become "air adviser"to Chiang Kai-shek, and to train fighter pilots for the Chinese Air Force.
Claire Lee Chennault was an American military aviator best known for his leadership of the "Flying Tigers" and the Republic of China Air Force in World War II.
Chiang Kai-shek, also known as Generalissimo Chiang or Chiang Chungcheng and romanized as Chiang Chieh-shih or Jiang Jieshi, was a Chinese politician and military leader who served as the leader of the Republic of China between 1928 and 1975, first in mainland China until 1949 and then in Taiwan until his death. He was recognized by much of the world as the head of the legitimate government of China until 1971, during which the United Nations passed Resolution 2758.
On 14 August 1937 the Chinese Air Force fighter squadrons sortied for the defense of Shanghai and Nanjing, capital of the Republic of China. In the afternoon of 14 August 1937, two groups of nine Japanese Mitsubishi G3M long-range bombers were launched from Japanese-occupied Taiwan on a mission to bomb Jianqiao Airfield in Hangzhou, Zhejiang, and Guangde Airfield in Anhui. The 21st and 23rd Squadrons, led by Kao Chi-hang, the Group Commander of the Chinese 4th Pursuit Group, took off from Jianqiao Airfield to intercept the Japanese bombers, despite the fact that some of the fighters had just flown in from Zhoukou and had not been refueled. Kao attacked a G3M bomber and scored a direct hit sending it plummeting to the ground in flames, and he also damaged another G3M bomber; it was the first air-to-air victory for the Chinese Air Force. Meanwhile, three other Hawk IIIs attacked a third G3M bomber and shot it down. The second group of Japanese G3M bombers attacking Guangde Airfield was intercepted by the 22nd Squadron of the 4th Pursuit Group and the 34th Squadron. Squadron Commander Cheng Hsiao-yu of the 22nd Squadron shot up the right engine and the wing fuel tank of one G3M bomber, forcing it to ditch before returning to its air base. The aerial battles in the afternoon of 14 August were a resounding victory for the Chinese Air Force, in which the Chinese Hawk III fighters destroyed four Japanese G3M long-range bombers without losing a single plane to the Japanese. In addition, two G3Ms were also shot down by ground anti-aircraft fire.
Nanjing, formerly romanized as Nanking and Nankin, is the capital of Jiangsu province of China and also the second largest city in the East China region, with an administrative area of 6,600 km2 (2,500 sq mi) and a total population of 8,270,500 as of 2016. The inner area of Nanjing enclosed by the city wall is Nanjing City (南京城), with an area of 55 km2 (21 sq mi), while the Nanjing Metropolitan Region includes surrounding cities and areas, covering over 60,000 km2 (23,000 sq mi), with a population of over 30 million.
The History of the Republic of China begins after the Qing dynasty in 1912, when the formation of the Republic of China as a constitutional republic put an end to 4,000 years of Imperial rule. The Qing dynasty,, ruled from 1644–1912. The Republic had experienced many trials and tribulations after its founding which included being dominated by elements as disparate as warlord generals and foreign powers.
The Mitsubishi G3M was a Japanese bomber and transport aircraft used by the Imperial Japanese Navy Air Service (IJNAS) during World War II.
On the following day at dawn 15 August, 12 Japanese Type 89 torpedo bombers were intercepted over Hangzhou by 21 Hawk IIIs of the Chinese 4th Pursuit Group led by Group Commander Kao Chi-hang. The Chinese shot down eight bombers. In the afternoon 20 Japanese G3M bombers on a raid to Nanjing were intercepted by 26 Chinese fighters from the 8th, 17th, 28th and 34th Squadrons flying eight Boeing 281 P-26 Peashooters, five Gloster Gladiators, 13 Hawk IIIs and Hawk IIs. The Chinese shot down four and damaged six Japanese G3M bombers.
On 16 August, the Japanese launched two raids with a total of 11 Japanese G3M bombers on the airfield near Nanjing; they were intercepted by five Chinese fighters from the 17th and 28th Squadrons. The Chinese shot down three Japanese bombers, and lost three fighters. On 17 August Chinese Hawk III fighters flew 17 sorties shooting down one Japanese bomber; the Chinese lost two aircraft. From 20 August to the end of the month, daily aerial engagements took place between the Chinese and Japanese planes, and the Japanese facing unexpected tenacity from the Chinese pilots, suffered prohibitive losses made worse by the sacrifice of armored protection in exchange for supposed-advantage of lighter-weight and higher-performance of the newer Japanese aircraft designs.In that period the Chinese shot down 24 Japanese planes and lost 11 aircraft.
In the first four months of the war from July to November 1937, the Chinese Air Force flew 137 sorties, attacking Japanese army positions, and engaged in 57 air battles with Japanese airplanes; the Chinese Air Force shot down 94 Japanese planes and damaged 52 on the ground, but lost 131 aircraft.The Chinese Air Force pilots fought well despite their airfields being under constant Japanese air attacks. To commemorate the heroic acts and sacrifices of the Chinese pilots in defense of their homeland, the Republic of China declared 14 August the Chinese Air Force Day known as the "814 Day", the day on which the Chinese Air Force scored its first air-to-air victory. In this initial phase of the war, the outnumbered Chinese had no replacements for their lost planes and experienced pilots killed in action, and began turning to the Soviet Union for new aircraft, while the Japanese were able to replace their lost planes with even more advanced aircraft, and continued to train new pilots.
In the period from the end of 1937 to 1940, support from the Americans was in decline, while the Soviet Union became the primary supplier of military aircraft to the Chinese Air Force, supplying 563 fighter planes and 322 bombers. Some of the planes were flown by Soviet volunteer military pilots sent to China. Aircraft provided by the Soviet Union included Tupolev SB twin-engine and Tupolev TB-3 4-engine bombers, and their latest Polikarpov I-15 biplane fighters and Polikarpov I-16 monoplane fighters.
According to records from the USSR,by the beginning of September 1938, China received from the Union of Socialist Soviet Republics 361 aircraft, of which 238 were I-15 and I-16 fighter planes. Together with the US and other foreign planes, the Chinese Air Force had a total of 602 aircraft. By the beginning of 1939, according to Chinese information, the Chinese Air Force had less than 100 aircraft of various types. A new group of 30 USSR I-15s arrived in Lanzhou on 18 July, while 30 USSR I-16s arrived on 3 August 1939.
From mid-1938 to mid-1939, Japanese forces intensified their attacks on the front near Lanzhou. The Japanese air units were operating from airfields in Shanxi at the margin of the operating range of their fighters, and their bombers were often not escorted by fighter planes. On 20 February 1939, thirty Japanese bombers flying in 3 formations were intercepted over Lanzhou by 40 USSR volunteer and Chinese fighters taking off in small groups at 5-minute intervals. In the ensuing battle, nine Japanese bombers were shot down, killing 63 crew members, and one USSR pilot was wounded. Three days later on 23 February, the USSR fighters intercepted 57 Japanese bombers on bombing raids to the city and airfield of Lanzhou; the USSR fighters shot down six Japanese bombers and forced the Japanese to abandon the airfield target. In the battles of February,the Chinese pilots of the 17th Squadron fought alongside the USSR volunteers.
In March 1939, the Chinese 4th Air Group, comprising 21st, 22nd, 23rd and 24th squadrons, was transferred to the airbase at Guangyangba for the defense of Chongqing. On 3 May, the 4th Air Group led by Group Commander Dong Mingde intercepted 54 Japanese bombers on their bombing raid to Chongqing,and shot down 7 Japanese bombers; deputy squadron commander Zhang Mingsheng (plane R-7153) was shot down and later died of his wounds. On 11 July, Chongqing was bombed by 27 Japanese bombers, which were met by eight I-15s led by Squadron Commander Zheng Shaoyu; Zheng's I-15 (No. 2310) had 38 bullets holes and I-15 (No. 2307) flown by pilot Liang Tianchen was shot down in flames.
In December 1939, the USSR fighter group, up to 50 planes under the command of S. P. Suprun was transferred to south Yunnan where Japanese air attacks on communications lines along the Chinese portion of the Burma Road had become more intense. Suprun's group participated in the Battle of South Guangxi,flying missions together with Chinese I-15 fighters from the 4th Air Group, the 27th and 29th Squadrons from the 3rd Air Group, part of the 18th Squadron with Curtiss Hawk 75, and even the 32nd Squadron with the ancient Douglas O-2MC scout/light bombers.
The USSR volunteer squadrons often flew their missions together with Chinese squadrons. From the beginning of 1938 to May 1940, USSR squadrons participated in more than 50 major air battles and together with Chinese squadrons shot down 81 Japanese aircraft, damaged 114 and 14 Japanese warships.In the summer of 1940, the USSR withdrew their volunteer pilots, leaving only a small number of advisers and technical personnel in China. They continued to supply aircraft to China until June 1941 when Germany invaded the Soviet Union
Curtiss Hawk 75, a new version of the Curtiss P-36 Hawk flown by Chinese pilots also took an active part in combat but did not achieve any special success. The Chinese 25th Squadron was the first unit to receive the new Hawk 75 and began to train in July 1938 under the direction of Claire Lee Chennault. On 18 August 1938, Squadron Commander Tang Pu-sheng led three Hawk 75s and 7 Polikarpov I-15s to intercept 27 Japanese planes over Hengyang; the Hawk 75s shot down one enemy plane and damaged another. Tang was shot down and killed; the other two Hawk 75s crashed during landing. The 16th Squadron of the 6th Bomber Air Group, having earlier flown the V-92 Corsair light bombers, was changed to a fighter squadron on 1 October 1938 and was sent to Zhiqiang, Hunan, to take possession of nine Hawk 75s. The pilots retrained under the direction of Chennault. At the end of the year, they were redeployed to Yibin, Sichuan, for air defense of the Chinese wartime capital of Chongqing. In January 1939, the squadron flew to Kunming, Yunnan, where it was disbanded in August the same year. Prior to 1 November 1938, the 18th Squadron was also included in the 6th Bomber Air Group, flying the Douglas O-2MC scout/light bombers; it was re-equipped with nine Hawk 75 fighters, and independently began retraining with its Squadron Commander Yang Yibaiin Yibin.
In January 1939 the 18th Squadron relocated to Kunming to defend the city from air attacks. On 1 August the squadron was rebased to Chongqing, and in December took part in the Battle of South Guangxi.At the beginning of 1940 it moved to Yunnan for defense of the Kunming-Mengzi railroad, which was subjected to massive air attacks. At the end of May the squadron returned to Chonqing; it did not have enough serviceable Hawk 75s, and was supplemented with nine old Hawk III biplanes from the 22nd Squadron.
On 8 February 1940, 27 Japanese planes heading for Mengzi were intercepted at 3.05 pm by three Hawk 75s of the 18th Squadron taking off from Kunming. In the ensuing dogfight, one Hawk 75 (No. 5024) was damaged and forced to crash land; its pilot Yang Tzu-fan was injured. On 13 February 1940 three Hawk 75s of the 18th Squadron intercepted 27 Japanese bombers which were on their way to bomb the bridge near Siulungtam. The Hawk 75s hit one Japanese bomber and were later joined by three I-15 biplane fighters. Together they made many passes at the damaged bomber, killing the upper gunner. The Chinese claimed to have finally shot down the hapless plane. Several of the Chinese planes were slightly damaged and one pilot, Tseng Pei-fu, was injured.
As early as in September 1937, Japan began to deploy its Mitsubishi A5M in the Chinese theatre. In the summer of 1940, Japan introduced its new Mitsubishi A6M Zero navy fighters for combat in China. The new Zero was far superior to the Soviet I-16 and American Hawk 75 fighter planes. The Chinese Air Force issued a general directive to its air units to adopt an "air dispersal tactics", and to avoid direct confrontation with Japanese fighters whenever possible.
On 4 October 1940 six Hawk 75s of the 18th Squadron were following the order to disperse to Guanxian when 27 Japanese Mitsubishi G3M bombers escorted by eight Japanese A6M Zeros led by Lieutenant Tamotsu Yokoyama on a bombing raid to Chengdu. The Japanese Zeros caught up with the Hawk 75s and shot one down, wounding the pilots of another two and forcing them to crash land, and set two Hawk 75s on fire on the ground while refueling.By December 1940 the 18th Squadron had ceased to exist in reality, and was disbanded in January 1941. The Hawk 75 fighters in the Chinese Air Force were later replaced by the American Curtiss P-40.
After withdrawing its volunteer pilots from China in the summer of 1940, the Soviet Union continued to supply aircraft to China until June 1941. Fighting continued on the northern front near Lanzhou, which was the Chinese terminus of the Chinese-Soviet transportation route. Chinese pilots were left to defend the northern front against Japanese air attacks.
On 21 May 1941 eight I-15s of the 21st Squadron and one I-15 from the 29th Squadron flying in 2 formations on patrol encountered 27 Japanese bombers over Lanzhou. The first group of I-15s led by Squadron Commander Chen Sheng-hsing shot down one of the Japanese Mitsubishi G3M long rang bombers and damaged another.On 22 May, 25 Japanese G3M bombers from the unit of Mihoro Kōkūtai were on a morning raid on Lanzhou. Seven Chinese I-16s of the 24th Pursuit Squadron and one Tupolev SB bomber of the 9th Bomb Squadron were ordered to disperse. Due to bad weather, the I-16s landed at Chung Chuan Chun Airfield just north of Lanzhou. As the Japanese bombers were sighted overhead, one of the I-16s flown by Kao You-hsing having just landed with the engine still running, took off to attack the Japanese planes, and shot down a G3M bomber flown by Lieutenant Shin-Taro Hashimoto and damaged another. The remaining six I-16s were able to take off and dispersed. On 26 May, Japanese fighters encountered 18 I-15s from the 29th Pursuit Squadron flying from Gansucheng to Lanzhou; two I-16s were shot down, both pilots bailing out, and the other 16 I-16s were destroyed on the ground when they landed for refuelling.
Since World War II erupted in Europe on 1 September 1939 after Nazi Germany invaded Poland, the United States had maintained its neutrality until the unannounced Japanese air attack on the American naval base at Pearl Harbor on 7 December 1941.In October 1940, China appealed to American president Franklin D. Roosevelt to allow the sale of military aircraft to China and the recruitment of American pilots for the resistance war against the Japanese invasion. In December, Washington approved China's request to recruit American pilots who would resign from U.S. military services and volunteer to serve in the Chinese Air Force. On 11 March 1941, the U.S. passed the Lend-Lease Act, which permitted the U.S. government to provide war equipment and material to Britain, France and other allied countries. In April, this policy was extended to China as well.
In August 1941, American Lockheed Hudson A-29 bombers arrived in China (22 planes turned over to Chinese Air Force).The Chinese 9th and 30th Bomber Squadrons were re-equipped with the Hudson A-29. In October 1941 the 9th Bomber Squadron was combat ready and flew bombing missions on Yuncheng, Shanxi, Hankou and other Japanese-occupied cities in China.
The American Volunteer Group, better known as the Flying Tigers, was officially formed on 1 July 1941, consisting of three squadrons of 30 planes each under the direct control and command of Claire Lee Chennault. In August, through the efforts of Chennault, 100 American volunteer pilots and about 200 mechanics and ground personnel were recruited. Curtiss-Wright Company also agreed to provide China 100 Curtiss Tomahawk P-40Bs, which had previously been rejected by Britain and later allocated to Sweden.
The Flying Tigers began to train in September 1941 in Taungoo, Burma, and with the help of the high speed and heavy armament (six 12.7mm machine guns) of the P-40 Warhawks and dissimilar air combat tactics against the dangerously nimble, though lightly armored Japanese fighters, the Flying Tigers saw immediate success.On 12 December 1941 the 3rd Squadron stationed in Rangoon joined the British Royal Air Force in defense of Rangoon. The 1st and 2nd Squadrons were sent to Kunming on 18 December, guarding Kunming and the Chinese section of the Burma Road against Japanese air attacks. On 20 December, the Flying Tigers saw their first action in the skies of Kunming when the 1st and 2nd Squadrons intercepted a formation of Japanese planes on a bombing raid; the Flying Tigers shot down nine of ten Japanese bombers and lost one P-40. Three days later, the Flying Tigers' 3rd Squadron inflicted comparable damage on a formation of Japanese planes on a bombing raid to Rangoon. For the next six months, the aerial battles of the Flying Tigers' P-40s with Japanese fighter and bomber aircraft were regular sights in the skies over south Yunnan and Burma.
When Rangoon fell to Japanese forces in early March 1942, Chennault withdrew all Flying Tigers squadrons to the base at Kunming. The Japanese fighter aircraft were more maneuverable as compared to the Flying Tigers's P-40. However, the Flying Tigers' pilots were able to take advantage of the fast diving speed and heavy firepower of their P-40s to gain an advantage over the lighter Japanese fighters. The American Volunteer Group was officially disbanded on 4 July 1942 when its one-year contract expired. The Group celebrated its final day by shooting down five Japanese fighters over Hengyang and escorting B-25 bombers of the United States Army Air Forces to bomb the Japanese air base at Guangzhou.In the short period of some six months from 20 December 1941 to the beginning of July 1942, the Flying Tigers had flown on more than 50 combat missions, destroying 299 Japanese planes including bombers, Nakajima Ki-43 fighters, and 153 probables; the Flying Tigers lost 12 planes in air battles and 61 on the ground; 13 pilots were killed and three were captured as prisoners of war. Those were incredible records in aerial combat. However, the Japanese immediate voiced their discontent with the American tactics through their English-language propaganda broadcasts by Tokyo Rose, who called the Americans "cowards", and continuously challenged the American pilots to "stop running away" (to the general amusement of the American pilots who tuned in to her broadcasts).
By the time the American Volunteer Group was officially disbanded on 4 July 1942, the United States had been a combatant in World War II for nearly seven months. Chennault was recalled to active duty in the United States Army Air Forces (USAAF); he was promoted to brigadier general to take command of the China Air Task Force (CATF),which was established on 14 July 1942 as a part of the 10th Air Force of USAAF. The 10th Air Force was activated on 12 February 1942 for operations in the China-Burma-India theatre of the war. Later in June 1942, Chennault was given the command of the 10th Air Force after the transfer of Commanding General Lewis Brereton to Egypt on 6 June 1942. The CATF included the four squadrons of P-40s of the 23rd Fighter Group and the 11th Bomber Group of B-25 Mitchells. Many of the fighter pilots in the CATF were former pilots of the Flying Tigers.
One of the aircraft contracts to be funded by the American Lend-Lease was to supply China with 125 P-43 Lancer fighter planes.In early 1942, shipments began of the P-43s in crates to China via Karachi, India, and they included some Vultee P-66 Vanguard fighters. The 4th Air Group of the Chinese Air Force was selected to receive and ferry the P-43s from India to Kunming. Many were lost in test flights and ferrying accidents. By August 1941, according to Chinese sources, the Chinese Air Forces received 41 operable P-43s. The 4th Air Group was sent to Chengdu to train on the new P-43s, and joined in the defense of Chengdu with the I-15s of the 17th Squadron and I-16s of the 29th Squadron. During the first half of 1942, there were few combat operations by pilots of the Chinese Air Force.
As of 13 August 1942, Chennault's CATF had also received five P-43s with five more promised. At this time, the CAFT consisted of 56 operational fighters, including P-40Bs, P-40Es and a few P-43s in four squadrons (the 16th, 74th, 75th and 76th) and eight B-25Cs of the 11th Bomb Squadron at Kunming, Guilin, Hengyang and Yunnan.
On 3 September, a P-43 flown by Lieutenant Martin Cluck of the 75th Squadron had to abort a reconnaissance mission due to mechanical trouble, Japanese fighters attacked him at low altitude near the air base and riddled his P-43. Cluck landed safely and escaped from his aircraft, but the P-43 was destroyed by Japanese strafing. One P-40 was also destroyed on the ground.
On 27 October 1942, 12 P-43s of the Chinese Air Force flying from Taipingsi, Sichuan, escorted nine A-29 Hudsons in a raid on Yungcheng, Shanxi. They destroyed one Japanese aircraft on the ground without suffering losses. In November, a mission of A-29 Hudsons was flown with escorts of P-66 Vanguards. In November, another bombing mission were flown escorted by P-43s. On 27 November, a bombing mission of A-29s was joined by Soviet SB bombers; in this mission one A-29 and three SB bombers were lost due to bad weather.On 30 December, three P-43s and six P-40s from the CATF flew an escort mission to Lashio, Burma; the P-43s provided top cover to the P-40s, enabling the P-40s to claim one of the six Japanese fighters encountered.
On 10 March 1943, Claire Lee Chennault was promoted to Major General, taking command also of the 14th Air Force,that was newly formed on 5 March 1943. On 19 March 1943, the CATF was incorporated into the United States Army as the 14th Air Force. The 10th and 14th Air Forces became the major American combat forces in the China-Burma-India theatre. The 14th Air Force took on the name of Flying Tigers. In the eight-month operations of the CATF from July 1942 to March 1943, they shot down 145 Japanese planes and 85 probables, and flew 65 bombing missions; they lost 16 P-40s and one B-25 Mitchell bomber.
In May 1943, the Japanese launched a ground offensive advancing into the area of Dongting Lake in northeastern Hunan and the region of the Yangtze River feeding to the lake. The objectives of the offensive were to secure the communication line and capture the fertile Chinese "Rice Bowl" region. To counter the Japanese offensive, both the 14th Air Force and the Chinese Air Force's 4th Air Group flying P-40s and P-43s provided air support to the Chinese ground troops.The 4th Group went into action on 19 May with 8 P-40Es and 4 P-43s escorting A-29 Hudson bombers over the enemy positions. On this mission, the Deputy Group Commander Xu Baoyun, flying a P-40E, was shot down by anti-aircraft gunfire. On 31 May Lieutenant-Colonel John Alison, an American ace and two USAAF wingmen led seven P-40s from the 4th Air Group escorting nine B-24 bombers to Yichang; Alison's P-40 was badly shot up by Captain Ohtsubo Yasuto, leader of the 1st Chutai (squadron) of the 33rd FR. Lieutenant Tsang Hsu-Lan, nicknamed "Bulldog" (plane No. 2304) of the 4th Group shot down Ohtsubo, saving Alison's life. Tsang was awarded the American Silver Star as well as China's highest decoration.
On 6 June, eight Japanese light bombers escorted by 14 fighters were on a raid on Liangshan. 13 P-40s from the Chinese Air Force led by Colonel Li Hsiang-yang were returning to Liangshan from a mission. Having just landed, Captain Chow Chin-kai, commander of the 23rd Squadron and veteran of many years combat ran from his P-40 to a P-66 parked nearby, and took off to attack the Japanese formation. While the Japanese fighters were strafing the airfield, Chow attacked the bombers and destroyed three. Despite Chow's heroic act, 12 P-40s and one fleet trainer were destroyed on the ground. Chow received the Blue-Sky-White-Sun (Chinese Nationalist emblem) award personally from Chiang Kai-shek.
By June 1943, the ground operations on the front of the "Rice Bowl" campaign were stabilized. In that campaign from 19 May to 6 June 1943, the Chinese Air Force flew on 336 fighter sorties and 88 bombing missions.The "Rice Bowl" campaign took its toll on the Chinese Air Force, which suffered heavy losses in combat and on the ground. At the end of the campaign the Chinese Air Force units numbered no more than a total of 77 combat aircraft, including seven A-29s, ten SBs, five P-40Es, nine P-43s and 46 P-66s, and of the total only 59 were serviceable. In May, the 14th Air Force received about 50 new P-40K, P-40M and P-40A fighters, and high-altitude Lockheed P-38 Lightning fighters in July, phasing out the old P-40s.
From July to September 1943, Japanese air units carried out concentrated attacks in three consecutive phases each targeting on a different area.The first phase from 22 July to 22 August concentrated on American air bases centered on Guilin, resulting in 50 American planes destroyed by the Japanese. The second phase began on 23 August, in which they targeted their attacks on Chongqing, Chengdu and eastern China air bases. At dawn on 23 August, 21 bombers escorted by 17 fighters took off from Hankou and were joined en route by another 14 fighters to strike an arsenal just to the west of Chongqing. A total of 29 fighters including ten P-40s, eight P-43s and 11 P-66s of the Chinese Air Force from the 4th and 11th Group at Peishiyi Airfield scrambled and took to the air to intercept. A flight of American fighters also scrambled from a distant air base but was too far to intercept. In the ensuing battle, the Japanese shot down two P-66s, one each of the P-40s and P-43s, and lost one bomber. The Chinese reported to have shot down three Japanese fighters and five bomber probables. In the third phase beginning in September, the Japanese resumed their attacks on targets in Guilin and Yunnan.
As a part of the 14th Air Force, Chennault created a special unit known as the Chinese-American Composite Wing(CACW) under his command. The CACW comprised the 1st Bomber Group, and the 3rd and 5th Fighter Groups with American pilots, and Chinese pilots from the Chinese Air Force, as well as American and Chinese ground crews. Since many of the Chinese pilots were young pilots of the Chinese Air Force, who had recently returned after completion of their training in the United States, lacking any combat experience, the unit was under an American commander, assisted by a staff of Chinese officers. The CACW was officially formed on 31 July 1943, and activated on 1 October 1943. The newly formed CACW were sent to Karachi, India, where they were re-equipped with B-25s and new P-40Ns, and trained under American supervision.
On 25 November 1943, am and staged through Suichwan, where they were refueled and joined by eight B-25s of the 11th Bomber Squadron and 16 fighter escorts of P-38s and P-51s from the 23rd Fighter Group of the 14th Air Force to attack Japan's largest air base in Taiwan, hitting a parking area, hangars, barracks, and buildings. The formation crossed the Taiwan Strait, flying at low altitude and caught the Japanese unprepared. 32 Japanese planes were destroyed in the air and on the ground while the Chinese did not lose a single plane. Seeing no opposing interceptors and only minimum anti-aircraft gun fire, Lieutenant Colonel Irving Branch of the CACW led his flight of bombers on a sweep down low strafing the airfield. The raid was the most successful thus far in the history of the 14th Air Force. Branch was awarded a Distinguish Flying Cross.six B-25s from the 2nd Bomber Squadron of the CACW took off from Guilin at 6
From late 1943 to the end of the war in August 1945, operations of the combined forces of the American and Chinese air units began to shift increasingly from defensive to offensive, and they eventually achieved air supremacy in China over Japanese air forces. It was made possible by the Americans' continuous supply of the latest war planes, fuel and material to China, and more importantly, the activation of the CACW as a unique Chinese component of the U.S. 14th Air Force, which was deployed in the China-Burma-India theatre, as well as the training by Americans of young Chinese pilots in the United States.
From 1944 onward, the CACW and other units of the Fourteenth Air Force were able to mount attacks against Japanese forces on all fronts in China, military installations, airbase in Taiwan, vital terminals of Japanese supply lines, which included Japanese-occupied river ports along the lower Yangtze River and Yellow River, seaports in southern China including Hong Kong and Hainan.
Separate missions were often flown daily by the CACW and other units of the 14th Air Force from different airbases with B-25 and B-24 bombers, P-40, P-38 and P-51 fighters. The following are some of the notable bombing missions and air combat on records during 1944.
On 11 February, six B-25 bombers escorted by 20 P-40 and P-51 fighters from the 14th Air Force including Chinese P-40s from the 32nd Fighter Squadron of the CACW bombed the storage area at Kai Tak Airfield, Hong Kong. The incoming formation encountered Japanese fighters from the 85th Sentai patrolling the area. In the ensuing air engagement the P-40s shot down five Japanese fighters and one probable, while the Japanese shot down one B-25, four P-40s and two P-51s and two probable fighters.
On 9 March, 18 CACW B-25s escorted by 24 P-40s bombed a foundry and floating docks at Huangshi in Hubei. They were intercepted by Japanese fighters from the 25th and 9th Sentai and lost 2 P-40s.
On 10 March, 2 bombers from the 2nd Bomber Squadron of the CACW bombed Japanese ships on the lower Yangtze; on returning flight one B-25 ran out of fuel and crash-landed killing its crew. On the same day, B-25s of the 14th Air Force escorted by P-38s attacked the river port at Anqing in Anhui. They sank a motor launch, damaged two cargo vessels and a barge; one of the Japanese intercepting fighters from the 25th Sentai flown by Moritsugu Kanai shot down one P-38.
On 29 March, 12 P-40s and three P-51s from the 14th Air Force attacked the railroad station area at Nanchang, and strafed the airfield and attacked a nearby bridge. Corporal Yasuzo Tanaka (Ki-44 Shoki-11) of the 25th Sentai was killed in Nanchang.
On 5 April, 26 Japanese A6Ms from the Sanya and Kaiko Kōkūtai took off from Hainan and carried out a major attack on Nanning in Guangxi; they destroyed two B-25s and three P-40s on the ground, and shot down nine P-40s (two unconfirmed), while eight A6Ms were shot down and their pilots killed.
By mid April, various Japanese air units had suffered heavy losses and had been replenished. The 25th Sentai was brought up to full strength with young pilots from Japan.
On 28 April, 26 B-24s from the 14th Air Force escorted by ten P-51 fighters carried out a bombing mission on the storage area north of Zhengzhou at the lower reaches of the Yellow River. The Japanese warning radar at Kaifeng was out of order, and the 9th Sentai stationed at Xinxiang with 10 Ki-44s failed to intercept. The B-24s pounded the storage area and damaged the Bawangcheng Bridge and another bridge on Yellow River.
On 3 May, seven B-25s of the CACW bombed Mihsien and hit numerous vehicles and Japanese troops northeast of Mihsien near Yueyang in northeastern Hunan, and strafed the town of Hsiangcheng. On the same day, ten CACW P-40s hit and damaged a bridge on the Yellow River northwest of Chenghsien near Luoyang, and destroyed 15 trucks and many troops.
On 2 June in a battle at China's Central Plain, seven P-40Ns from the 7th fighter Squadron of the CACW made an attack on an airfield at Zhengzhou where a Japanese air transport unit was based. Seven Japanese K-44 fighters of the 9th Sentai led by Captain Kobayashi intercepted the Chinese P-40Ns, and shot down five, including the one flown by the Flight Commander Zhang Lemin. The 9th Sentai lost one flown by Sergeant Fumio Oguri over Bawangcheng.
On 12 June, about 100 P-40s and P-51s from the 14th Air Force attacked numerous supply boats and other river and lake traffic in the Dongting Lake area, and hit docks and warehouses at Yuanjiang, and also villages and troops in Changsha.
On 28 August, 32 P-40s from the 14th Air Force, including 11 from the 5th Fighter Squadron of the CACW, attacked the Japanese air base at Pailuchi and targets of opportunity at Hengyang. They were intercepted by Japanese K-43s from the 48th Sentai and Ki-84s from the 22nd Sentai. In the air battle, the Japanese destroyed one Chinese and three American P-40s while the CACW shot down six enemy planes; one of the pilots from the 49th Sentai reportedly parachuted from his burning Ki-84 but drowned in the Yangtze River.
On 29 August, 13 P-40s from the 3rd Fighter Group of the CACW bombed and strafed shipping and dock facilities at Shayang in Hubei. After the attack, they were intercepted by 21 Japanese fighters near Jiayu. The CACW claimed a total of seven victories with Group Commander Lieutenant Colonel Bill Reed and his wingman Lieutenant Tan Kun each shooting down one Ki-43, and the other Chinese P-40s claiming five Japanese fighters. Commander Meng Shao-yi of the 28th Squadron of the CACW was shot down and killed.
On 29 August around 1 pm, 13 Japanese Ki-84s from the 22nd Sentai and 16 Ki-43s from the 25th Sentai, a total of 29 fighters engaged a large number of B-24s, P-40s and P-51s of the 14th Air Force near Yueyang in northeastern Hunan. The Japanese shot down four P-40s and one P-51, and damaged four B-24s, four P-40s and one P-51, and lost one Ki-43 and one Ki-84, and suffered damage on one Ki-84.
On 12 September, two separate groups from the 5th Fighter Group of the CACW engaged in air battles over northeastern Hunan. First Lieutenant Phil Colman of the 26th Squadron claimed one damaged Ki-43, and his wingman Lieutenant Yang Shaohua claimed one Ki-43 shot down over Xiangtan; Colman further claimed one Ki-43, two damaged Ki-43s and a probable "Hamp" (A6M Type Zero) over Changsha. Another group of eight P-40s fought 12 Japanese fighters including six Ki-84s over Hengshan just south of Xiangtan; Captains Reynolds and Ramsey each claimed a damaged Japanese fighters, but Lieutenant Tom Brink was shot down while strafing, and one P-40 flown by Lieutenant Su Yinghai was badly damaged and written off after returning to base.
On 26 October B-24s and B-25s of the 14th Air Force attacked shipping off the east Leizhou Peninsula situated opposite to Hainan in the South China Sea. Major Horace S. Carswell Jr. of the 308th Bomber Group was awarded the Medal of Honour for his action on that day when he attacked a Japanese convoy in the South China Sea under intense anti-aircraft fire. His B-24, No. 44-40825 (MARC 9612) was so badly damaged that when his plane reached over land, he ordered the crew to bail out. One crew member could not jump because his parachute had been ripped by flak, so Carswell remained with the aircraft to try to save the crew member by attempting to crash land. Before Carswell could attempt a crash landing, the bomber struck a mountainside and burned.
By the end of 1944, the continued bombings and attacks on Japanese supply lines and storage facilities in Japanese-occupied China had caused a severe shortage of fuel greatly hampering the operations of Japanese air units. The American and Chinese air forces in China had inflicted heavy losses to the Japanese air forces operating in China, and forced the Japanese to adopt a defensive stance.
On 28 January 1945, the Burma Road was fully restored as a land transport route for war material supplied to China by the Allies. It had been cut off when Japanese invaded Burma in 1942, leaving available only the air supply route over "The Hump", from Assam, India, over the eastern end of the Himalayas. The re-opening of the Burma Road greatly increased the supply of aircraft, spare parts, fuel and other war material as required for the successful prosecution of the war.
In the beginning of 1945, the total numbers of the Chinese and American air forces exceeded 800 aircraft. During the concluding period of the war from January to June 1945, the Chinese pilots and their American counterparts participated actively in battles supporting ground forces on all fronts in central, southern and eastern China.
The CACW unofficial combat record in the time from its activation on 1 October 1943 to the end of the war in August 1945 included 190 Japanese aircraft destroyed in the air, 301 on the ground. At the same time, they lost 35 fighters and eight bombers to enemy ground fire, and 20 fighters to Japanese aircraft. However, not a single CACW bomber was lost to enemy fighters, a tribute to the abilities of the Wing's B-25 aircrews, and the quality of the escort protection provided by the Wing's fighter pilots.The CACW produced five American air aces and three Chinese air aces, and was disbanded on 19 September 1945.
The following are some of the notable air operations in 1945.
On 5 January a combined group of 28 P-40N and P-51D fighters from the 14th Air Force flew from Laohekou in Hubei to attack the Japanese airfield at Wuhan, destroying 50 Japanese aircraftin the air and on the ground. One Chinese pilot was shot down and killed in the air battle.
On 9 March about 50 fighters and bombers from the 14th Air Force on armed reconnaissance attacked railroad targets, river and road traffic, bridges, gun positions, and troops at several locations, particularly around Guiyi, Hengyang, Nanjing and Xinyang.
On 10 March about 60 fighters and bombers from the 14th Air Force hit targets in rivers, on roads and railroads, gun positions, warehouses, airstrips, and troops around Xinyang, Yiyang, Changsha, Qiyang, Yueyang, Hengyang in Hunan, and Hankou, and Wuchang in the neighboring Hubei province.
On 16 March, 32 B-24s from the 14th Air Force escorted by 10 P-51s pounded the north railroad yards at Shijiazhuang.
On 15 April, about 200 fighters and bombers from the 14th Air Force attacked Japanese targets in areas from southern China to the northern China plain hitting numerous targets including bridges, river shipping, town areas, trucks, railroad traffic, gun positions, storage areas, and general targets of opportunity.
On 8 May, Japanese forces moved the bulk of their 5th Kokugun to Korea. It involved the relocation of some 10,000 ground support personnel, leaving a skeleton of air units in China. The move was completed by the end of the month with only minor losses.
On 10 August, about 50 P-47s and P-51s from the 14th Air Force attacked river and railroad targets, troops, trucks, and bridges at several points in southern and eastern China.
On 15 August, Japan's unconditional surrender was announced, and all offensive operations against Japan ended.
On 18 August, the vice-commander of the 24th Pursuit Squadron from the Chinese Air Force, Guo Fengwu flew over Guisui (known as Hohhot after 1954) in Inner Mongolia to drop leaflets which contained the text of Japanese Emperor Hirohito's surrender decree. He was shot down by Japanese anti-aircraft gun fire, and became the last casualty of the Chinese Air Force in the eight-year-long war.
On 2 September 1945, hostilities with Japan ended officially with the signing of the instrument of surrender aboard the USS Missouri (BB-63) in Tokyo Bay.
Chinese-American Composite Wing (CACW)
Some of the aircraft types used in the Second Sino-Japanese War:
Chinese and American Air Units
Japanese Air Units
The Curtiss P-40 Warhawk is an American single-engined, single-seat, all-metal fighter and ground-attack aircraft that first flew in 1938. The P-40 design was a modification of the previous Curtiss P-36 Hawk which reduced development time and enabled a rapid entry into production and operational service. The Warhawk was used by most Allied powers during World War II, and remained in frontline service until the end of the war. It was the third most-produced American fighter of World War II, after the P-51 and P-47; by November 1944, when production of the P-40 ceased, 13,738 had been built, all at Curtiss-Wright Corporation's main production facilities at Buffalo, New York.
The First American Volunteer Group (AVG) of the Chinese Air Force in 1941–1942, nicknamed the Flying Tigers, was composed of pilots from the United States Army Air Corps (USAAC), Navy (USN), and Marine Corps (USMC), recruited under President Franklin Roosevelt's authority before Pearl Harbor and commanded by Claire Lee Chennault. The aircraft were to fly with Chinese colors but be under American control. The mission was to bomb Japan and defend China but many delays meant they flew in combat after the US and Japan declared war.
The Fourteenth Air Force is a numbered air force of the United States Air Force Space Command (AFSPC). It is headquartered at Vandenberg Air Force Base, California.
The American Volunteer Groups were volunteer air units organized by the United States government to aid the Nationalist government of China against Japan in the Second Sino-Japanese War. The only unit to actually see combat was the 1st AVG, popularly known as the Flying Tigers.
Witold Urbanowicz was a Polish fighter ace of the Second World War. According to the official record, Witold Urbanowicz was the second highest-scoring Polish fighter ace, with 17 confirmed wartime kills and 1 probable, not counting his pre-war victory. He was awarded with several decorations, among others the Virtuti Militari and British Distinguished Flying Cross. He also published several books of memoirs.
Thomas Buchanan McGuire Jr. was an Irish American United States Army major who was killed in action while serving as a member of the United States Army Air Forces during World War II and posthumously awarded the Medal of Honor. He was one of the most decorated American fighter pilots and the second highest scoring American ace of the war.
David Lee "Tex" Hill was an American fighter pilot and triple flying ace. He is credited with 12 ¼ victories as a squadron leader with the Flying Tigers and another six as an officer in the United States Army Air Corps in World War II. He retired as a brigadier general.
The Republic of China Air Force (ROCAF) was formed by the Kuomintang after the establishment of the Aviation Ministry in 1920. As tensions mounted between China and Imperial Japan in the 1930s, a number of smaller Chinese warlord airforce men and equipment became integrated into the ROCAF in a centralized effort to counter Imperial Japanese military ambitions.
William Arthur "Bill" Shomo was a United States Army Air Forces fighter pilot during World War II. He is credited with eight victories during the conflict. Seven of these occurred during a single mission while flying a reconnaissance version of the P-51 Mustang, for which he received the Medal of Honor.
Neel Ernest Kearby was a United States Army Air Forces colonel and P-47 Thunderbolt pilot in World War II who received the Medal of Honor for his actions in combat. Kearby is the first United States Army Air Forces fighter pilot to receive Medal of Honor. He scored total 22 aerial victories and remains the top scoring P-47 pilot in the Pacific Theater.
The China Air Task Force (CATF) was a combat organization of the United States Army Air Forces created in July 1942 under the command of Brig. Gen. Claire Chennault, after the Flying Tigers of the 1st American Volunteer Group of the Chinese Air Force were disbanded on 4 July of that month. It consisted of the 23rd Fighter Group with four squadrons, the assigned 74th, 75th, 76th, and attached 16th Fighter Squadrons, plus the 11th Bombardment Squadron. It was a subordinate unit of the Tenth Air Force in India, commanded by Brig. Gen. Earl Naiden and by Maj. Gen. Clayton Bissell. "Chennault had no respect for Bissell as a combat airman," wrote his biographer Martha Byrd, and "Bissell had no respect for Chennault as an administrator." Their relationship, she wrote, was ugly.
The 24th Pursuit Group is an inactive United States Air Force unit. It was wiped out in the Battle of the Philippines (1941–42). The survivors fought as infantry during Battle of Bataan and after their surrender, were subjected to the Bataan Death March, although some did escape to Australia. The unit was never remanned or equipped. It was carried as an active unit until 2 April 1946.
Clinton Dermott "Casey" Vincent was an American flying ace who became the second youngest general officer in United States Army Air Forces history. Vincent was one of Claire Chennault's two top fighter commanders in the China Burma India Theater of World War II. He served as the model for two comic strip characters by Milton Caniff: "Colonel Vince Casey", and "Brigadier General P.G. 'Shanty' Town".
The Chinese-American Composite Wing (Provisional) was a joint United States Army Air Forces and a Republic of China Air Force organization. It was administratively assigned to Fourteenth Air Force in China during World War II.
Aerial ramming or air ramming is the ramming of one aircraft with another. It is a last-ditch tactic in air combat, sometimes used when all else has failed. Long before the invention of aircraft, ramming tactics in naval warfare and ground warfare were common. The first aerial ramming was performed by Pyotr Nesterov in 1914 during the First World War. In the early stages of World War II the tactic was employed by Soviet pilots who called it taran, the Russian word for "battering ram".
Attacks on parachutists, as defined by the law of war, is when pilots, aircrews, and passengers are attacked while descending by parachute from disabled aircraft during wartime. This practice is considered by most militaries around the world to be inhumane, barbaric, and unchivalrous, that it is unnecessary killing, and that it is contrary to fair play. Attacking parachutists from aircraft in distress is a war crime under the Protocol I addition to the 1949 Geneva Conventions. Firing on airborne forces who are descending by parachute is not prohibited.
The bombing of Rangoon was a series of air raids conducted by the Imperial Japanese Army Air Service that took place between December 1941 to March 1942 during the Burma Campaign of World War II. The capital city of Rangoon was the first to be attacked after Japan executed air raids on Burma in preparation for its invasion of the country weeks following its declaration of war upon the United States and the United Kingdom on December 8, 1941.
Lieutenant Colonel George Bray McMillan was a United States Army Air Forces fighter pilot, Squadron Commander, combat "ace" and member of the American Volunteer Group better known as the Flying Tigers.
