Japanese air attacks on the Mariana Islands and anti-aircraft guns shot down about 37 Japanese aircraft during these raids. After the Marianas began to come under attack, the United States military stepped up its raids on the Japanese-held islands which could be used to launch raids on the B-29 bases. Particular attention was given to Iwo Jima, as it was correctly assumed that the Japanese aircraft which attacked the Marianas were flying from Japan and staging through the island en route to their targets. Following the first raid against Saipan in November, XXI Bomber Command B-29s were dispatched against Iwo Jima's airfields on November 5 and 8.
Japanese occupation of the Andaman Islands created a brief reign of terror on Car Nicobar as they rounded up forced labour amongst the Nicobarese. The occupation left a legacy of lasting bitterness towards the Japanese, and to some extent towards their collaborators in the "Arzi-Hukumat-e Azad Hind", amongst the generation which experienced it. Japanese Vice Admiral Hara Teizo, and Major-General Tamenori Sato surrendered the islands to Brigadier J A Salomons, commander of 116th Indian Infantry Brigade, and Chief Administrator Mr Noel K Patterson, Indian Civil Service, on 7 October 1945, in a ceremony performed on the Gymkhana Ground, Port Blair.
