bodies of the four Japanese crew of the two midget submarines sunk in Sydney Harbour and had them cremated at Eastern Suburbs Crematorium. For the cremation, the Allies draped the Japanese flag over each coffin and rendered full naval honours. Muirhead-Gould was criticised for this, but defended his actions as respecting the courage of the four submariners, regardless of their origin. Australian politicians also hoped that the Japanese Government would notice the respect paid to the sailors and improve the conditions Australian prisoners-of-war were experiencing in Japanese internment camps. Japanese authorities noted the funeral service, but this did not lead to any major improvement in conditions for Australian POWs. Following the use of the midget submariners' funeral by the Japanese for propaganda purposes, the Australian High Command forbade similar funerals for enemy personnel in the future. An exchange of Japanese and Allied diplomatic personnel stranded in the opposing nations occurred in August 1942, which allowed Tatsuo Kawai, the Japanese ambassador to Australia, to return home with the ashes of the four Japanese submariners. When the exchange ship Kamakura Maru arrived in Yokohama, several thousand people were present to honour the four men. The two main targets of the attack, USS Chicago and HMAS Canberra, were both lost within the next year: Canberra sinking on 9 August 1942 during the Battle of Savo Island, and Chicago on 30 January 1943 following the Battle of Rennell Island. None of the Japanese submarines involved in the attack survived the war. and sank I-21 on 5 February 1944 off the Marshall Islands. An American torpedo boat sank I-22 on 25 December 1942 off New Guinea. An American patrol craft sank I-24 on 10 June 1943 near the Aleutian Islands. and sank I-27 on 12 February 1943 off the Maldives. Lastly, sank I-29 on 26 July 1944 in the Philippines. M-14 and M-21 The Allies located and recovered M-21 on 3 June and M-14 on 8 June. Although both were damaged during the attack, it was possible to assemble a complete submarine from the two vessels. The centre section of the rebuilt submarine was mounted on a trailer and taken on a tour throughout southern New South Wales, Victoria, and western South Australia. The purpose of the tour was twofold; it allowed Australians to see a Japanese midget submarine up close, and was used to raise A£28,000 for the Naval Relief Fund and other charities.
