The Arakan Campaign of 1942–43 was the first tentative Allied attack into Burma, following the Japanese conquest of Burma earlier in 1942, during the Second World War. The British Army and British Indian Army were not ready for offensive actions in the difficult terrain they encountered, nor had the civil government, industry and transport infrastructure of Eastern India been organised to support the Army on the frontier with Burma. Japanese defenders occupying well-prepared positions repeatedly repulsed the British and Indian forces, who were then forced to retreat when the Japanese received reinforcements and counter-attacked.

The Battle of Pakokku and Irrawaddy River operations were a series of battles fought between the British Indian Army and the Imperial Japanese Army and allied forces over the successful Allied Burma Campaign on the China Burma India Theater during World War II. The battles and operations were instrumental in facilitating the eventual capture of Rangoon in summer 1945.

Operation Battleaxe was a British Army offensive during the Second World War to raise the Siege of Tobruk and re-capture eastern Cyrenaica from German and Italian forces. It was the first time during the war that a significant German force fought on the defensive. The British lost over half of their tanks on the first day and only one of three attacks succeeded.

The rapid British advance during Operation Compass forced the Italian 10th Army to evacuate Cyrenaica, the eastern province of Libya. In late January, the British learned that the Italians were retreating along the Litoranea Balbo from Benghazi. The 7th Armoured Division was dispatched to intercept the remnants of the 10th Army by moving through the desert, south of the Jebel Akhdar via Msus and Antelat as the 6th Australian Division pursued the Italians along the coast road, north of the jebel. The terrain was hard going for the British tanks and Combeforce, a flying column of wheeled vehicles, was sent ahead across the chord of the jebel.

The Battle of Bir Hakeim took place at Bir Hakeim, an oasis in the Libyan desert south and west of Tobruk, during the Battle of Gazala. The 1st Free French Brigade defended the position from 26 May – 11 June against much larger Axis forces of Panzerarmee Afrika/Armata Corazzata Africa. The Panzerarmee captured Tobruk ten days later but the delay imposed on the Axis offensive by the defence of the fortress influenced the cancellation of Operation Herkules, a plan for an Axis invasion of Malta. Rommel continued to advance and invaded Egypt, slowed by British delaying actions until the First Battle of El Alamein in July, where the Axis advance was stopped. Both sides used the battle for propaganda, Winston Churchill renamed the Free French as the Fighting French and Hitler called the French the second best fighters after the Germans.

The Battle of Christmas Island was a small engagement which began on 31 March 1942, during World War II. Assisted by a mutiny by soldiers of the British Indian Army against their British officers, Imperial Japanese Army troops were able to occupy Christmas Island without any land-based resistance. The United States Navy submarine Seawolf caused severe damage to the Imperial Japanese Navy cruiser Naka during the landings.

Operation Compass was the first large British military operation of the Western Desert Campaign (1940–1943) during the Second World War.

Operation Creek was a military operation undertaken by the Special Operations Executive in World War Two on 9 March 1943. It involved a covert attack by members of the Calcutta Light Horse and the Calcutta Scottish against a Nazi German merchant ship, the Ehrenfels, which had been transmitting information to U-boats from Mormugao Harbour in neutral Portugal's territory of Goa.

Operation Crusader was a military operation of the Western Desert Campaign during World War II by the British Eighth Army against the Axis forces in North Africa commanded by Generalleutnant Erwin Rommel. The operation was intended to bypass Axis defences on the Egyptian–Libyan frontier, to defeat the Axis armoured forces and to relieve the 1941 Siege of Tobruk.

The Battle of Damascus was the final action of the Allied advance on Damascus in Syria during the Syria–Lebanon Campaign in World War II. The initial advance was undertaken by Indian troops who were tasked with capturing Mezzeh while Free French forces were to capture Qadam. While the Free French were held up, the Indian troops were able to capture Mezzeh and then became cut off following a Vichy French counterattack. British and Australian reinforcements were brought up and throughout 19–20 June, the Indian troops holding Mezzeh continued to hold out despite running low of ammunition and rations. Late on 20 June, Australian troops attempted to relieve them and entered the town, arriving to find that the town was deserted, as the remaining Indian troops had been captured by the Vichy French and removed from the town earlier in the day. The following day, the Free French, supported by British and Australian troops, captured Qadim and throughout 21 June further actions were fought around the Quneitra road and the Barada Gorge. By mid-morning on 21 June the Vichy French garrison in Damascus surrendered to the Allied forces.

The Battle of Gemmano took place during World War II, between the dates of September 4th, and September 15th of 1944. The battle occurred in the area of the Gothic Line, near the Apennine Mountains in northern Italy, which would soon turn out to be the last line of defense for the Axis Powers in Italy. The village of Gemmano was eventually captured on September 9th, 1944 by the invading Eighth Army, but two more subsequent attacks were needed to secure the area surrounding the village of Gemmano. Fighting was so fierce, similar to that of the famous battle of Monte Cassino, that the battle was sometimes referred to as, “ The Cassino of the Adriatic”.

The Battle of Imphal took place in the region around the city of Imphal, the capital of the state of Manipur in northeast India from March until July 1944. Japanese armies attempted to destroy the Allied forces at Imphal and invade India, but were driven back into Burma with heavy losses. Together with the simultaneous Battle of Kohima on the road by which the encircled Allied forces at Imphal were relieved, the battle was the turning point of the Burma campaign, part of the South-East Asian Theatre of the Second World War. The Japanese defeat at Kohima and Imphal was the largest up until that time, with many of the Japanese deaths resulting from starvation, disease and exhaustion suffered during their retreat.

The Anglo-Soviet invasion of Iran, also known as the Anglo-Soviet invasion of Persia, was the joint invasion of Iran by the United Kingdom and the Soviet Union in August 1941.

The Italian campaign of World War II consisted of Allied and Axis operations in and around Italy, from 1943 to 1945. The Joint Allied Forces Headquarters (AFHQ) was operationally responsible for all Allied land forces in the Mediterranean theatre and it planned and led the invasion of Sicily in July 1943, followed in September by the invasion of the Italian mainland and the campaign in Italy until the surrender of the German Armed Forces in Italy in May 1945.

The Italian invasion of Egypt was an offensive in the Second World War, against British, Commonwealth and Free French forces in the Kingdom of Egypt. The invasion by the Italian 10th Army ended border skirmishing on the frontier and began the Western Desert Campaign (1940–1943) proper. The Italian strategy was to advance from Libya along the Egyptian coast to seize the Suez Canal. After numerous delays, the scope of the offensive was reduced to an advance as far as Sidi Barrani and the engagement of any British forces in the area.

The Japanese Invasion of Malaya began just after midnight on 8 December 1941 before the attack on Pearl Harbor. It was the first major battle of the Pacific War, and was fought between ground forces of the British Indian Army and the Empire of Japan.

The battle took place in three stages from 4 April to 22 June 1944 around the town of Kohima, the capital of Nagaland in northeast India. From 3 to 16 April, the Japanese attempted to capture Kohima ridge, a feature which dominated the road by which the besieged British and Indian troops of IV Corps at Imphal were supplied. By mid-April, the small British and Indian force at Kohima was relieved.
The Malayan campaign was a military campaign fought by Allied and Axis forces in Malaya, from 8 December 1941 – 31 January 1942 during the Second World War. It was dominated by land battles between British Commonwealth army units, and the Imperial Japanese Army with minor skirmishes at the beginning of the campaign between British Commonwealth and Royal Thai Armed Forces. The Japanese had air and naval supremacy from the opening days of the campaign. For the British, Indian, Australian and Malayan forces defending the colony, the campaign was a total disaster.

The battle developed as the Afrika Korps pursued the Eighth Army as it retreated into Egypt. Rommel intended to engage and destroy the Allied infantry formations in detail, before the British had a chance to regroup. The Axis cut off the line of retreat of X Corps and XIII Corps but was too weak to stop the British from breaking out. The fortress port of Mersa Matruh and 6,000 prisoners were captured, along with a great deal of supplies and equipment but the Eighth Army survived.
