BF-52
Left Lorient at 05:06 this morning. At 14:31 lookouts spied a S-class submarine 102 kilometers South-West of Brest, heading towards Lorient. I wasn't about to let a threat like that near my base, so U-111 submerged and got into position. At 14:49 one G7e was launched at 1 meter depth. At 14:50 torpedo impacted right behind the S-class' forward torpedo tubes. The resulting explosion killed the sub pretty much instantly. Continuing voyage to BF-17.
