The history of Cuba during World War II begins in 1939. Because of Cuba's geographical position at the entrance of the Gulf of Mexico, Havana's role as the principal trading port in the West Indies, and the country's natural resources, Cuba was an important participant in the American Theater of World War II, and subsequently one of the greatest beneficiaries of the United States' Lend-Lease program. Cuba declared war on the Axis powers in December 1941,making it one of the first Latin American countries to enter the conflict, and by the war's end in 1945 its military had developed a reputation as being the most efficient and cooperative of all the Caribbean nations.
The island of Cuba was inhabited by various Mesoamerican cultures prior to the arrival of the Spanish in 1492. After the arrival, Spain conquered Cuba and appointed Spanish governors to rule in Havana. In 1762, Havana was briefly occupied by Great Britain, before being returned to Spain in exchange for Florida. A series of rebellions during the 19th century failed to end the Spanish rule. However, the Spanish–American War resulted in a Spanish withdrawal from the island in 1898, and following three-and-a-half years of subsequent US military rule, Cuba gained formal independence in 1902.
Cuba, officially the Republic of Cuba, is a country comprising the island of Cuba as well as Isla de la Juventud and several minor archipelagos. Cuba is located in the northern Caribbean where the Caribbean Sea, Gulf of Mexico and Atlantic Ocean meet. It is east of the Yucatán Peninsula (Mexico), south of both the U.S. state of Florida and the Bahamas, west of Haiti and north of both Jamaica and the Cayman Islands. Havana is the largest city and capital; other major cities include Santiago de Cuba and Camagüey. The area of the Republic of Cuba is 110,860 square kilometres (42,800 sq mi). The island of Cuba is the largest island in Cuba and in the Caribbean, with an area of 105,006 square kilometres (40,543 sq mi), and the second-most populous after Hispaniola, with over 11 million inhabitants.
The Gulf of Mexico is an ocean basin and a marginal sea of the Atlantic Ocean, largely surrounded by the North American continent. It is bounded on the northeast, north and northwest by the Gulf Coast of the United States, on the southwest and south by Mexico, and on the southeast by Cuba. The U.S. states of Texas, Louisiana, Mississippi, Alabama, and Florida border the Gulf on the north, which are often referred to as the "Third Coast", in comparison with the U.S. Atlantic and Pacific coasts.
Federico Laredo Brú was the President of Cuba when the war began in 1939. His one significant World War II-related crisis before leaving office in 1940 was the MS St. Louis affair. The MS St. Louis was a German ocean liner carrying over 900 Jewish refugees from Germany to Cuba. Upon arriving in Havana, the Cuban government refused to allow the refugees to land because they did not have proper permits and visas. After sailing north, the United States and Canadian governments also refused to accept the refugees, and so the St. Louis sailed back across the Atlantic, and dropped her passengers off in Europe. Some thenceforth went to Britain, but most went to Belgium and France, which were soon overrun by German forces. Ultimately, because of the refusal to take in the Jewish refugees, many were taken prisoner by the Germans and subsequently killed in concentration camps.
Dr. Federico Laredo Brú was an attorney and served as President of Cuba from 1936 to 1940. He was married to Leonor Gomez-Montes (1880-?).
The President of the Republic of Cuba, officially called President of the Council of State between 1976 and 2019, is the head of the Council of State of Cuba. The office in its current form was established under the Constitution of 2019. The president is the second most powerful position, after the First Secretary of the Communist Party of Cuba.
MS St. Louis was a German ocean liner known for carrying more than 900 Jewish refugees from Germany in 1939. Originally intending to debark in Cuba, they were denied permission to land. The captain, Gustav Schröder, went to the United States and Canada, trying to find a nation to take them in, but both refused. He finally returned the ship to Europe, where various European countries, including Belgium, the Netherlands, the UK, and France, accepted some refugees. Many were later caught in Nazi roundups of Jews in occupied countries, and historians have estimated that approximately a quarter of them died in death camps during World War II. These events, known as the "Voyage of the Damned" in one account, have inspired film, opera, and fiction.
Following the 1940 Cuban elections, Brú was succeeded by the "strongman and chief" of the Cuban Army, Fulgencio Batista. At first, the United States was concerned about Batista's intentions; whether he would align his country with the Axis cause, or that of the Allies. Batista, shortly after becoming president, legalized a pro-fascist organization linked to Francisco Franco and his regime in Spain, but fear of any Nazi sympathies was dispelled when Batista sent the British a large quantity of sugar as a gift. Later, fear of Batista's possible sympathy for Franco was also dispelled when the president suggested to the United States that it launch a joint US-Latin American invasion of Spain, in order to overthrow Franco and his regime. This plan, however, did not materialize.
Fulgencio Batista y Zaldívar was the elected President of Cuba from 1940 to 1944, and the U.S.-backed authoritarian ruler from 1952 to 1959, before being overthrown during the Cuban Revolution. Batista initially rose to power as part of the 1933 Revolt of the Sergeants, which overthrew the provisional government of Carlos Manuel de Céspedes y Quesada. He then appointed himself chief of the armed forces, with the rank of colonel, and effectively controlled the five-member "pentarchy" that functioned as the collective head of state. He maintained this control through a string of puppet presidents until 1940, when he was himself elected President of Cuba on a populist platform. He then instated the 1940 Constitution of Cuba and served until 1944. After finishing his term he lived in Florida, returning to Cuba to run for president in 1952. Facing certain electoral defeat, he led a military coup against President Carlos Prío Socarrás that preempted the election.
Francisco Franco Bahamonde was a Spanish general and politician who ruled over Spain as a military dictator from 1939, after the nationalist victory in the Spanish Civil War, until his death in 1975. This period in Spanish history is commonly known as Francoist Spain.
Sugar is the generic name for sweet-tasting, soluble carbohydrates, many of which are used in food. The various types of sugar are derived from different sources. Simple sugars are called monosaccharides and include glucose, fructose, and galactose. "Table sugar" or "granulated sugar" refers to sucrose, a disaccharide of glucose and fructose. In the body, sucrose is hydrolysed into fructose and glucose.
Batista's support for the Allied cause was confirmed in February 1941, when he ordered all German and Italian consular officials to leave his country. Cuba entered the war on December 9, 1941, by declaring war on Japan, which a few days before had launched a devastating attack on the United States Navy base at Pearl Harbor, Hawaii. Cuba then declared war on Germany and Italy on December 11, 1941, and - following the Americans' example - broke relations with Vichy France on November 10, 1942.
The Kingdom of Italy was a state which existed from 1861—when King Victor Emmanuel II of Sardinia was proclaimed King of Italy—until 1946—when a constitutional referendum led civil discontent to abandon the monarchy and form the modern Italian Republic. The state was founded as a result of the unification of Italy under the influence of the Kingdom of Sardinia, which can be considered its legal predecessor state.
The United States Navy (USN) is the naval warfare service branch of the United States Armed Forces and one of the seven uniformed services of the United States. It is the largest and most capable navy in the world and it has been estimated that in terms of tonnage of its active battle fleet alone, it is larger than the next 13 navies combined, which includes 11 U.S. allies or partner nations. with the highest combined battle fleet tonnage and the world's largest aircraft carrier fleet, with eleven in service, and two new carriers under construction. With 319,421 personnel on active duty and 99,616 in the Ready Reserve, the Navy is the third largest of the service branches. It has 282 deployable combat vessels and more than 3,700 operational aircraft as of March 2018, making it the second largest and second most powerful air force in the world.
Pearl Harbor is a lagoon harbor on the island of Oahu, Hawaii, west of Honolulu. It has been long visited by the Naval fleet of the United States, before it was acquired from the Hawaiian Kingdom by the U.S. with the signing of the Reciprocity Treaty of 1875. Much of the harbor and surrounding lands is now a United States Navy deep-water naval base. It is also the headquarters of the United States Pacific Fleet. The U.S. government first obtained exclusive use of the inlet and the right to maintain a repair and coaling station for ships here in 1887. The attack on Pearl Harbor by the Empire of Japan on December 7, 1941, was the immediate cause of the United States' entry into World War II.
According to Rear Admiral Samuel Eliot Morison, Cuba's military was the "most cooperative and helpful of all the Caribbean states" during the war, and that its navy was "small but efficient" in its fight against German U-boats. Upon Cuba's declaration of war on the Axis powers, Batista signed an agreement with the United States that gave the latter permission to build airfields in Cuba for the protection of the Caribbean sealanes, and he also signed a mutual defense pact with Mexico for the defense against enemy submarines in the Gulf of Mexico. Among the new American bases was the San Antonio Air Base near San Antonio de los Baños, and the San Julián Air Base in Pinar del Rio, both of which were built in 1942 and turned over to the Cuban military after the war. The United States also supplied Cuba with modern military aircraft, which were vital for coastal defense and anti-submarine operations, and refitted the Cuban Navy with modern weapons and other equipment.During World War II, the Cuban Navy escorted hundreds of Allied ships through hostile waters, sailed nearly 400,000 miles on convoy and patrol duty, flew over 83,000 hours on convoy and patrol duty, and rescued over 200 U-boat victims from the sea, all without losing a single warship or aircraft to enemy action. But even though the Cuban military was praised for its conduct, rumors persisted throughout the war that the Germans were operating small bases hidden in coves along Cuba's coast, which were used to resupply the U-boats. However, this fear was unjustified, and the lack of such bases in the Caribbean forced the Germans to develop supply submarines, the German Type XIV submarine nicknamed "milk cows", for logistics.
Samuel Eliot Morison was an American historian noted for his works of maritime history and American history that were both authoritative and popular. He received his Ph.D. from Harvard University in 1912, and taught history at the university for 40 years. He won Pulitzer Prizes for Admiral of the Ocean Sea (1942), a biography of Christopher Columbus, and John Paul Jones: A Sailor's Biography (1959). In 1942, he was commissioned to write a history of United States naval operations in World War II, which was published in 15 volumes between 1947 and 1962. Morison wrote the popular Oxford History of the American People (1965), and co-authored the classic textbook The Growth of the American Republic (1930) with Henry Steele Commager. Over the course of his distinguished career, Morison received eleven honorary doctoral degrees, and garnered numerous literary prizes, military honors, and national awards from both foreign countries and the United States, including two Pulitzer Prizes, two Bancroft Prizes, the Balzan Prize, the Legion of Merit, and the Presidential Medal of Freedom.
Mexico, officially the United Mexican States, is a country in the southern portion of North America. It is bordered to the north by the United States; to the south and west by the Pacific Ocean; to the southeast by Guatemala, Belize, and the Caribbean Sea; and to the east by the Gulf of Mexico. Covering almost 2,000,000 square kilometres (770,000 sq mi), the nation is the fifth largest country in the Americas by total area and the 13th largest independent state in the world. With an estimated population of over 120 million people, the country is the eleventh most populous state and the most populous Spanish-speaking state in the world, while being the second most populous nation in Latin America after Brazil. Mexico is a federation comprising 31 states and Mexico City, a special federal entity that is also the capital city and its most populous city. Other metropolises in the state include Guadalajara, Monterrey, Puebla, Toluca, Tijuana and León.
San Antonio de los Baños Airfield is a military air base located near San Antonio de los Baños, a municipality in the province of Havana in Cuba. It is located approximately 3 mi (4.8 km) southwest of the city of San Antonio de los Baños, about 30 mi (48 km) southwest of Havana.
Cuba lost six merchant ships during the war, and the Cuban Navy was credited with sinking one German submarine. The first four sunken merchant ships were the Manzanillo, a steamer of 1,025 tons, the 1,685 ton Santiago de Cuba, the 1,983 ton Mambi, and the 5,441 ton Libertad. Manzanillo was sunk with the Santiago de Cuba on August 12, 1942, by U-508. The two ships were sailing in Special Convoy 12 when they were attacked off the Florida Keys. Altogether, thirty-three sailors were killed in what became the deadliest attack on the Cuban merchant marine during the war. Thirty others survived.
German submarine U-508 was a Type IXC U-boat of Nazi Germany's Kriegsmarine during World War II.
The Florida Keys are a coral cay archipelago located off the southern coast of Florida, forming the southernmost portion of the continental United States. They begin at the southeastern coast of the Florida peninsula, about 15 miles (24 km) south of Miami, and extend in a gentle arc south-southwest and then westward to Key West, the westernmost of the inhabited islands, and on to the uninhabited Dry Tortugas. The islands lie along the Florida Straits, dividing the Atlantic Ocean to the east from the Gulf of Mexico to the northwest, and defining one edge of Florida Bay. At the nearest point, the southern part of Key West is just 90 miles (140 km) from Cuba. The Florida Keys are between about 23.5 and 25.5 degrees North latitude.
The next engagement occurred on May 13, 1943, when U-176 sank Mambi. Mambi was with Convoy NC-18, sailing six miles off Manati, when she was hit by a single torpedo, sinking her quickly. Twenty-three men were killed, including five American United States Navy Armed Guards, who manned the ship's weapons. Eleven others survived, including the ship's master and one of the armed guards. The 2,249 ton American ship SS Nickeliner was also sunk during the same attack, after being struck by two torpedoes. The first torpedo explosion lifted the ship's bow out of the water and threw up a column of water and flames about 100 feet into the air. The second damaged the tanks of ammonia water the ship was carrying. Miraculously, the crew, which included seven armed guards, escaped into lifeboats without a single loss of life. They were rescued by a Cuban submarine chaser as Nickeliner sank, and landed at Nuevitas.
Libertad was the largest Cuban merchant ship sunk in the war. On the morning of December 4, 1943, the 5,441-ton Libertad was sailing about seventy-five miles southwest of North Carolina's Cape Hatteras, with Convoy KN-280 (sailing Key West to New York), when the U-129 attacked her. Launching four torpedoes, U-129 struck Libertad twice on the port side, causing the ship to first list severely and then sink rapidly. The crew had no time to send out distress signals, and were still lowering life rafts when the sea water reached the deck of the ship. Twenty-five men were killed, and eighteen others were rescued by the United States Navy after several hours adrift at sea.
The final two Cuban merchant ships were sunk in February 1944, apparently without the loss of life. Altogether, Cuba lost 10,296 tons of shipping during the war, as well as about eighty lives, including that of the American armed guards. Today there is a monument in Havana's Avenida del Puerto for the people who died in the attacks.
The only U-boat sunk by the Cuban Navy was U-176, which was the submarine that had sunk Mambi and Nickeliner. On May 15, 1943, a squadron of Cuban submarine chasers, formed by the CS-11, CS-12 and CS-13, sailed from Isabela de Sagua toward Havana escorting the Honduran ship Wanks, and the Cuban ship Camagüey, both of which were loaded with sugar. The crews of the merchant ships, as well as those of the warships were on full alert. Just before their departure, a warning had been received that a surfacing submarine had been detected off the northern coast of Matanzas.
The ships sailed in forward lines 500 yd (460 m) apart. Camagüey was on the flank nearest to the coast. The escort navigated at a distance of 750–1,000 yd (690–910 m). The CS-12 was in front, followed by the CS-11 with the squadron chief on board and, finally, the CS-13 was at the rear. At 17:15, when the convoy was off of Cayo Megano, an American Kingfisher floatplane appeared in the sky coming from the northeast. The plane went into a nosedive and, flying at low altitude, circled twice, swaying, and turning on and off its engine. According to an established code, the maneuvers were used to announce the presence of a German U-boat, and to mark its exact position. The Kingfisher then dropped a smoke float.
After dropping the float, the Cuban squadron chief ordered the commander of CS-13, Ensign Mario Ramirez Delgado, to explore the area pointed out by the plane. Once the order was received, the CS-13 sailed speedily toward the area, where the patrol boat's sonar received a clear and precise contact at 900 yards. The seaman operating the sonar, Norberto Collado Abreu, was glued to the equipment, without missing a sound. Then the attack started: three depth charges set to explode at 100, 150, and 250 feet, were dropped from the stern, in accordance with the calculated speed of the submarine.
Four explosions were clearly detected. The fourth explosion was so strong that the stern of the Cuban ship was submerged and water came in through the hatchway of the engine room. At that time the hydrophones reported a sound similar to a liquid bubbling when it comes from a submerged container that is suddenly opened. The sounds indicated that the U-boat had been hit. To finish the U-boat off, the patrol boat launched two more depth charges, set to explode at 250 feet. A few minutes later, a dark stain was observed on the surface of the water. A spurt of a black and viscous substance smelling like gasoline came up from the deep. Although there was little doubt that the U-boat had been sunk, Delgado was ordered to take a sample of the contaminated seawater to confirm the victory. But even then it was not until after the war, when the Allies seized Germany's naval records, that proof of U-176's sinking was found. According to the seized documents, U-176 was under the command of Captain Lieutenant Reiner Dierksen, had sunk eleven enemy ships in her career, and was herself sunk with all hands lost.
The exploration of the battle area with the hydro-acoustic equipment continued for a short time after the engagement, but no sound was detected. The CS-13 then joined the convoy again and continued its crossing. Upon arrival in Havana, and after personally informing the Head of the Navy, Delgado spoke on the phone with President Batista, who ordered him to keep absolute silence about what had happened. For some unknown reason, according to Delgado, the sinking of U-176 remained a secret to the Cuban public until after the end of the war. In 1946, Delgado was finally awarded the Meritorious Naval Service Order with Red Badge. Furthermore, Samuel Eliot Morison recognized his success in his work History of United States Naval Operations in World War II, where he also praised the ability and efficiency of the Cuban Navy.
Samuel Eliot Morison wrote the following about the engagement:
|“||…The CS-13 patrol boat, commanded by Second Lieutenant Mario Ramirez Delgado, turned toward the gas, made good contact through the sonar and launched two perfect attacks with deep charges which annihilated U-176. This was the only successful attack against a submarine done by a surface unit smaller than a PCE of 180 feet, thus, the sinking is properly considered with great pride by the small but efficient Cuban Navy.||”|
German espionage activity in Cuba was minor, despite the country's importance to the Allied war-effort, and was eliminated by Allied counter-intelligence before it could really begin. Shortly after the beginning of the war, the Germans began operating a clandestine communications network in South America to collect secret information and safely smuggle it out of the region to Occupied Europe. For Cuba, the Abwehr sent a man named Heinz Lüning to Havana with orders to establish a secret radio station and then transmit the information he collected to agents in South America, where it would then be sent directly to Germany.
According to author Thomas Schoonover, the plan could have worked, but Lüning was an incompetent spy who failed to master the very basics of espionage. For example, he was never able to get his radio working correctly, he did not understand how to use the secret ink he was supplied with, and he missed drop boxes. But in spite of all this, after his premature arrest in August 1942, Allied officials - including President Batista, General Manuel Benítez, J. Edgar Hoover, and Nelson Rockefeller - attempted to fabricate a link between Lüning and the German submarines operating in the Caribbean - by claiming that he was in contact with them via radio - in order to provide the public with an explanation for their failures early in the U-boat campaign. Allied officials elevated Lüning's importance to that of a "master spy," but there is no evidence that he ever came across even a single piece of important intelligence during his time in Cuba. Lüning was found guilty of espionage and executed in Cuba in November 1942, becoming the only German spy put to death in Latin America during World War II.
Ernest Hemingway was living at his home, Finca Vigía, in Cuba when the war began in 1939. His first contribution to the Allied war-effort without leaving the island was to organize his own counter-intelligence force to root out any Axis spies operating in Havana. Calling it his "Crook Factory," Hemingway's unit consisted of eighteen men, many of whom he had worked with five years before during the Spanish Civil War. The effort was unsuccessful, however, and Hemingway soon turned his attention to fighting the German U-boats operating in the Caribbean Sea.
Just three weeks after receiving permission from Ambassador Spruille Braden to form the "Crook Factory," Hemingway asked Braden for permission to arm his fishing boat, the Pilar , for patrols against U-boats off of the Cuban coast. Surprisingly, Baden gave Hemingway permission, and so the latter proceeded with arming the Pilar and the crew with machine guns, bazookas, and hand grenades. Hemingway's plan was similar to that of the Q-ship idea: He would sail around in what appeared to be a harmless pleasure craft, inviting the Germans to surface and board, and when they did, the boarding party would be disposed of with the machine guns, and the U-boat would then be engaged with the bazookas and grenades.
Hemingway's patrols against German U-boats turned out to be just as unsuccessful as the counter-intelligence operation was. As the months passed, and as no U-boat appeared, the Pilar's patrols turned into fishing trips, and the grenades were thrown into the sea as "drunken sport." After adding his sons Patrick and Gregory to the crew, Hemingway acknowledged that his U-boat hunting venture had "turned into a charade," but he never admitted it straightforwardly. Years later, the Cuban naval officer Mario Ramirez Delgado, who sank U-176, said Hemingway was "a playboy that hunted submarines off the Cuban coast as a whim."
