Southern Asia 1942: Indian Ocean Raid
5 April 1942
World War II: The South-East Asian Theater
Indian Ocean Raid
The first three months of 1942 had seen the almost total defeat of the Allies in Southeast Asia, with Japan conquering Malaya and Singapore, southern Burma, and the Dutch East Indies. In an attempt to destroy the last British naval presence in the region, the Japanese launched a carrier force into the Indian Ocean. However, despite raiding the naval base of Colombo and destroying a number of ships, the Japanese failed to catch the main British force before it moved out of range.

British Protectorates in the Persian Gulf
The British Residency of the Persian Gulf maintained British India’s influence in a number of Gulf states from the 19th Century until 1947. These states were nominally independent - and shown as such in most atlases from the period - but all signed treaties guaranteeing British control over their foreign affairs.
The Sultanate of Muscat and Oman was the only one of these states with significant international relations, having obtained trade agreements with the US and France before it signed its treaty with Britain. Maps of the time often show Trucial Oman and even Qatar as regions of Oman.
Trucial Oman was the region to the west of Oman which collectively signed treaties with Britain. The sheikhdoms of this region were often called the Trucial States, and later became the United Arab Emirates. However at this time they had little unity, with no regional council until 1952.
The British Indian Empire, also known as the British Raj, was comprised of a complex of presidencies, provinces, protectorates, and agencies. Only the top level subdivisions are shown here.
The area under direct British rule was known as British India and made up of presidencies and provinces - a presidency simply being the name for an older province.
Outside British India, but often included within the sphere of the presidencies/provinces, were the hundreds of protectorates or ‘princely states’. These were indirectly ruled states, the largest being Hyderabad, Kashmir, and Mysore. The others were either collected into agencies - which might in turn contain other smaller agencies - or fell under the sway of the provinces.
