南雲忠一
Between 31 March and 10 April 1942 the Japanese conducted a naval sortie against Allied naval forces in the Indian Ocean. The Fast Carrier Task Force ("Kidō Butai"), consisting of six carriers commanded by Admiral Chūichi Nagumo, inflicted heavy losses on the British fleet, with the sinking of 1 carrier, 2 cruisers, 2 destroyers, and 23 merchant ships for the loss of 20 aircraft. Attacks on the island of Ceylon were also carried out.
