The military history of the United Kingdom in World War II covers the Second World War against the Axis powers, starting on 3 September 1939 with the declaration of war by the United Kingdom and France, followed by the UK's Dominions, Crown colonies and protectorates on Nazi Germany in response to the invasion of Poland by Germany. There was little, however, the Anglo-French alliance could do or did do to help Poland. The Phoney War culminated in April 1940 with the German invasion of Denmark and Norway. Winston Churchill became prime minister and head of a coalition government in May 1940. The defeat of other European countries followed – Belgium, the Netherlands, Luxembourg and France – alongside the British Expeditionary Force which led to the Dunkirk evacuation in June 1940.
The 11th Army Group was the main British Army force in Southeast Asia during the Second World War. Although a nominally British formation, it also included large numbers of troops and formations from the British Indian Army and from British African colonies, and also Nationalist Chinese and United States units.
The British Fourteenth Army was a multi-national force comprising units from Commonwealth countries during the Second World War. As well as British Army units, many of its units were from the Indian Army and there were also significant contributions from British Army's West and East African divisions. It was often referred to as the "Forgotten Army" because its operations in the Burma Campaign were overlooked by the contemporary press, and remained more obscure than those of the corresponding formations in Europe for long after the war. For most of the Army's existence, it was commanded by Lieutenant-General William Slim.
IV Corps was a corps-sized formation of the British Army, formed in both the First World War and the Second World War. During the First World War the corps served on the Western Front throughout its existence. During the Second World War it served in Norway and Britain until it was transferred to India, which was threatened with attack after Japan entered the war.
The Burma campaign was a series of battles fought in the British colony of Burma. It was part of the South-East Asian theatre of World War II and primarily involved forces of the Allies against the invading forces of the Empire of Japan. Imperial Japan was supported by the Thai Phayap Army, as well as two collaborationist independence movements and armies. The first of these was the Burma Independence Army, which spearheaded the initial attacks against the country. The Indian National Army, led by Subhas C. Bose of the Free India movement, after earlier collaborating with Nazi Germany, fought under or alongside Imperial Japan, especially during Operation U-Go in 1944. Nominally independent puppet states were established in the conquered areas and some territories were annexed by Thailand. In 1942 and 1943, the international Allied force in British India launched several failed offensives to retake lost territories. Fighting intensified in 1944, and British Empire forces peaked at around 1 million land and air forces. These forces were drawn primarily from British India, with British Army forces, 100,000 East and West African colonial troops, and smaller numbers of land and air forces from several other Dominions and Colonies. These additional forces allowed the Allied recapture of Burma in 1945.
The South-East Asian Theatre of World War II consisted of the campaigns of the Pacific War in the Philippines, Thailand, Indonesia, Indochina, Burma, India, Malaya and Singapore between 1941 and 1945.
The Battle of the Admin Box took place on the southern front of the Burma campaign from 5 to 23 February 1944, in the South-East Asian Theatre of World War II.
General Sir Montagu George North Stopford was a senior British Army officer who fought during both World War I and World War II. The latter he served in with distinction, commanding XXXIII Indian Corps in the Far East, where he served under Field Marshal Sir William Slim, and played a significant role in the Burma Campaign, specifically during the Battle of Kohima in mid-1944.
Operation Zeppelin was a major military deception operation run by the British during the Second World War. It formed part of Operation Bodyguard, the cover plan for the invasion of Normandy in 1944, and was intended to mislead German intelligence as to the Allied invasion plans in the Mediterranean theatre that year. The operation was planned by 'A' Force and implemented by means of visual deception and misinformation.
The 36th Indian Infantry Division was an infantry division of the Indian Army during the Second World War. The division was subsequently redesignated as a British Army formation, the 36th Infantry Division in September 1944. It served in India and during the Burma Campaign. After the end of the war it was disbanded and its remaining British units were transferred to the British 2nd Infantry Division.
The 78th Infantry Division, also known as the Battleaxe Division, was an infantry division of the British Army, raised during the Second World War that fought, with great distinction, in Tunisia, Sicily and Italy from late 1942–1945.
The 76th Infantry Division was an infantry division of the British Army, which was formed in November 1941 and served during the Second World War. It was created when the Norfolk County Division, initially raised in 1940 to defend the Norfolk coast from a potential German invasion, was redesignated. The division maintained the defensive duties that had been assigned to it, prior to it being renamed, until late 1942 when it became a training formation. It was then responsible for providing final tactical and field training to soldiers who had already passed their initial training. After five additional weeks of training, the soldiers were posted to fighting formations overseas. The formation was used as a source of reinforcements for the 21st Army Group, that was fighting in the Normandy campaign. After all available British troops had left the United Kingdom for France, the division was disbanded in September 1944.
The 80th Infantry (Reserve) Division was an infantry division of the British Army formed at the beginning of 1943, during the Second World War. For the twenty months that the division existed, it was a training formation. It was made responsible for providing final tactical and field training to soldiers who had already passed their initial training. After five additional weeks of training, the soldiers would be posted to fighting formations overseas. Notably, the division was used as a source of reinforcements for the 21st Army Group, which was fighting in Normandy. After all available troops left the United Kingdom for France, the division was disbanded.
The 7th Infantry Division is a war-formed infantry division, part of the British Indian Army that saw service in the Burma Campaign.
The Burma campaign in the South-East Asian Theatre of World War II was fought primarily by British Commonwealth, Chinese and United States forces against the forces of Imperial Japan, who were assisted by the Burmese National Army, the Indian National Army, and to some degree by Thailand. The British Commonwealth land forces were drawn primarily from the United Kingdom, British India and Africa.
The British Indian XXXIII Corps was a corps-sized formation of the Indian Army during the Second World War. It was disbanded and the headquarters was recreated as an Army headquarters in 1945.
The XV Corps was a corps-sized formation of the British Indian Army, which was formed in India during the Second World War. It took part in the Burma Campaign and was disbanded after the end of the war. While part of the British Indian Army, it included other commonwealth units, namely the 22nd and 28th East African Brigades.
XIV Corps was a British infantry corps during the First World War. During the Second World War the identity was recreated for deceptive purposes.
