World War II: The British Indian Army and Imperial Japanese Army begin a series of battles known as the Battle of Pokoku and Irrawaddy River operations.
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.
The British Indian Army, commonly referred to as the Indian Army, was the main military of the British Indian Empire before its decommissioning in 1947. It was responsible for the defence of both the British Indian Empire and the princely states, which could also have their own armies. The Indian Army was an important part of the British Empire's forces, both in India and abroad, particularly during the First World War and the Second World War.
The term Indian Army appears to have been first used informally, as a collective description of the Presidency armies (the Bengal Army, the Madras Army and the Bombay Army) of the Presidencies of British India, particularly after the Indian Rebellion. The first army officially called the Indian Army was raised by the government of India in 1895, existing alongside the three long-established presidency armies. However, in 1903 the Indian Army absorbed these three armies. The Indian Army should not be confused with the Army of India (1903–1947) which was the Indian Army itself plus the British Army in India (British units sent to India).
