The sinking of a Japanese submarine off the coast of Australia in World War II was a rare event.
German surface raiders had first inflicted heavy damage with mines and guns, one of them sinking the cruiser HMAS Sydney. Then the Japanese arrived, using aircraft in massive bombing raids across the north, with fierce resistance from Allied fighters, radar, and anti-aircraft guns. Submarines joined in, sinking freighters off the coasts. But here the Allies were ineffective at returning fire.
A submarine was sunk off Darwin, and two of the midget raiders which attacked Sydney Harbour were sent to the seabed – that was all. A fight between two RAAF bombers, which actually caught a submarine on the surface – rather than attacking echoes and eddies – is unusual. The I-178, it seems, was surprised and then disabled so she could not dive.
She fought it out, with anti-aircraft guns against the bombers’ depth charges and machineguns. She lies, lost, with her crew of 88, somewhere north of Sydney.
This analytical account from Australia’s leading naval historian is full of detail about life, living, fighting, and dying in WWII submarines and in their most deadly opponent, the aerial bomber.
