So there I was, dec. 17, 1942, in a radar equipped Gato at radar depth tracking a western bound freighter just off the eastern entrance to the Inland Sea. It was 2 hours before sundown. I was tracking the ship on Radar, waiting until dark so I could surface and get close enough to attack when all of a sudden, without warning an explosion shatters my sub and sends it straight to the seabed at 280 feet. Despite the best efforts of my crew, the sub flooded and so ended my first TMO career. Probably an aircraft spotted me.
...this is fun.
