I hear what you say Colin, but twelve miles is not much, as vessels sinking due drift for a while before all reserve buoyancy goes, but the Aussies according to their report I read when the wreck was found did not fit the description they gave of her damage and strange out of a large naval crew , there were no survivors. But at the end of the day, the Sydney closed in very close to unknown vessel without taking any precautions according to the Germans and she suffered the ultimate price, a lot of people suffered, not just the crew, because the senior officers were not on the ball.
