[2] On 22 February 1944 British Chivalry was sailing alone in the Indian Ocean, south-west of Addu Atoll in the Maldive Islands, on a voyage from Melbourne to Abadan while in ballast.
For the next two hours it circled, firing indiscriminately at the lifeboats and men in the water before finally moving off.
The thirty-eight survivors were adrift for 37 days before finally being rescued by the British cargo liner MV Delane.
[5] It was not until 1978 that it was revealed that Nakagawa, while in command of the submarine I-177, had also been responsible for the sinking of the Australian hospital ship Centaur in April 1943, with the loss of 268 lives.
[4] The men killed aboard British Chivalry are commemorated on Panel 19 of the Tower Hill Memorial in London.
