Twelfth Army (United Kingdom)

The Allied invasion of Sicily, also known as the Battle of Sicily and Operation Husky, was a major campaign of World War II in which the Allied forces invaded the island of Sicily in July 1943 and took it from the Axis powers. It began with a large amphibious and airborne operation, followed by a six-week land campaign, and initiated the Italian campaign.

The 21st Army Group was a British headquarters formation formed during the Second World War. It controlled two field armies and other supporting units, consisting primarily of the British Second Army and the First Canadian Army. Established in London during July 1943, under the command of Supreme Headquarters Allied Expeditionary Force (SHAEF), it was assigned to Operation Overlord, the Western Allied invasion of Europe, and was an important Allied force in the European Theatre. At various times during its existence, the 21st Army Group had additional British, Canadian, American, and Polish field armies or corps attached to it. The 21st Army Group operated in Northern France, Luxembourg, Belgium, the Netherlands and Germany from June 1944 until August 1945, when it was renamed the British Army of the Rhine (BAOR).

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 the 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.

The 6th Airborne Division was an airborne infantry division of the British Army during the Second World War. Despite its name, the 6th was actually the second of two airborne divisions raised by the British Army during the war, the other being the 1st Airborne Division. The 6th Airborne Division was formed in the Second World War, in mid-1943, and was commanded by Major-General Richard N. Gale. The division consisted of the 3rd and 5th Parachute Brigades along with the 6th Airlanding Brigade and supporting units.

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. 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 Fourth Army was a field army that formed part of the British Expeditionary Force during the First World War. The Fourth Army was formed on 5 February 1916 under the command of General Sir Henry Rawlinson to carry out the main British contribution to the Battle of the Somme.

General Sir Montagu George North Stopford, was a senior British Army officer who fought during both the First and Second World Wars. The latter he served in with distinction, commanding XXXIII Indian Corps in the Far East, where he served under General Sir William Slim, and played a significant role in the Burma Campaign, specifically during the Battle of Kohima in mid-1944.

Fourteenth United States Army was a fictitious/military deception field army, under the command of John P. Lucas, developed under Operation Quicksilver as a part of the fictitious First United States Army Group.

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.

First United States Army Group was a fictitious Allied Army Group in World War II prior to D-Day, part of Operation Quicksilver, created to deceive the Germans about where the Allies would land in France. To attract Axis attention, prominent US general George S. Patton was placed in command of the fabricated formation.

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 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.

At the start of 1939, the British Army was, as it traditionally always had been, a small volunteer professional army. At the beginning of the Second World War on 1 September 1939, the British Army was small in comparison with those of its enemies, as it had been at the beginning of the First World War in 1914. It also quickly became evident that the initial structure and manpower of the British Army was woefully unprepared and ill-equipped for a war with multiple enemies on multiple fronts. During the early war years, mainly from 1940 to 1942, the British Army suffered defeat in almost every theatre of war in which it was deployed. But, from late 1942 onwards, starting with the Second Battle of El Alamein, the British Army's fortunes changed and it rarely suffered another defeat.

XIV Corps was a British infantry corps during the First World War. During the Second World War the identity was recreated for deceptive purposes.

The Battle of the Sittang Bend and the Japanese Breakout across Pegu Yomas were linked Japanese military operations during the Burma Campaign, which took place nearly at the end of World War II. Surviving elements of the Imperial Japanese Army who had been driven into the Pegu Yoma attempted to break out eastwards in order to join other Japanese troops retreating from the British forces. The break-out was the objective of the Japanese Twenty-Eighth Army with support at first from the Thirty-Third Army and later the Fifteenth Army. As a preliminary, the Japanese Thirty-Third Army attacked Allied positions in the Sittang Bend, near the mouth of the river, to distract the Allies. The British had been alerted to the break-out attempt and it ended calamitously for the Japanese, who suffered many losses, with some formations being wiped out.
