1603 hours - In position 36°31'N, 23°13'E spots three Arado 196 seaplanes and shortly afterwards a convoy of one UJ boat, one motor lighter and one siebel ferry came into view.

The leighter was close astern of the UJ boat and the siebel ferry was about 3/4 to one nautical mile astern of the leighter. Lt. Piper decided to attack the UJ boat and the leighter with a salvo of four torpedoes from his bow tubes.

1641 hours - Fired four torpedoes from about 1500 yards. Two torpedoes were aimed at the UJ boat and two at the leighter. Two torpedoes were heard to explode. These explosions were followed by a considerable number of heavy and violent explosions. Lt. Piper first thought that they were being depth charges but later it became clear that it were the depth charges that were exploding as the UJ boat was sinking.

1652 hours - Returned to periscope depth and saw the siebel ferry picking up survivors. There was no sign of the UJ boat and the leighter.

1655 hours - Ordered one torpedo reload

1711 hours - No.4 tube was ready. A cat and mouse game with the siebel ferry started. Each time when Unsparing was in attack position it started its engines to pick up more survivors a small distance away. Also the aircraft were still circling low but they were most likely unable to see the submarine as they took no offensive action.

1740 hours - The siebel ferry started up both engines again and started to make off to Monemvasia. Two minutes later Lt. Piper fired the torpedo in no.4 tube that was seen to hit the siebel ferry aft. This did however not sink it !, but its motive power was finished.

Another torpedo reload was ordered that was completed in 11 minutes.

1907 hours - Fired this torpedo. It was seen to explode with a terrific flash and the target disintegrated.

Lt. Piper did not pick up any survivors as prisoners of war because the aircraft were still overhead. (3)
