The Indian Ocean raid, also known as Operation C or Battle of Ceylon in Japanese, was a naval sortie carried out by the Imperial Japanese Navy (IJN) from 31 March to 10 April 1942. Japanese aircraft carriers under Admiral Chūichi Nagumo struck Allied shipping and naval bases around British Ceylon, but failed to locate and destroy the bulk of the British Eastern Fleet. The Eastern Fleet, commanded by Admiral Sir James Somerville, was forewarned by intelligence and sailed from its bases prior to the raid; its attempt to attack the Japanese was frustrated by poor tactical intelligence.

Chūichi Nagumo was an admiral in the Imperial Japanese Navy (IJN) during World War II. Nagumo led Japan's main carrier battle group, the Kido Butai, in the attack on Pearl Harbor, the Indian Ocean raid and the Battle of Midway. He never recovered from the crushing defeat at Midway, and committed suicide during the Battle of Saipan.
