Imperial Japanese Navy Officer's cap badge : Japanese midget submarine Accession Number: RELAWM31562

Description

Standard Imperial Japanese Navy officer's peaked cap cloth badge with salt water immersion damage. The gold anchor usually found centrally mounted is missing; and the gilded brass wreath decoration, as well as the surmounting silver cherry blossom are coated in verdigris.

Contextual Description

This badge was removed from the uniform of one of the crew members of one of the two Japanese midget submarines which were recovered from Sydney Harbour in June 1942.

On the night of 31 May 1942 three Japanese midget submarines entered Sydney Harbour. One (HA-14) became entangled in the boom net across the harbour, and her occupants blew her up. A second (M-24) entered the harbour and fired torpedoes at the cruiser USS Chicago. They missed the Chicago but one hit the barracks ship HMAS Kuttabul, killing 21 naval ratings. This midget submarine disappeared, its fate a complete mystery until it was discovered by a group of amateur divers off Sydney's northern beaches in November 2006. A third midget submarine (HA-21) also entered the harbour but was destroyed by depth-charges before it fired any torpedoes.
The badge is from either Ha-14 or HA-21.
