[John Pancoast]

Running convoy battle during one night. Course 140. Called in wolf pack starting at late afternoon. Once the sun had set, received notice that the pack was assembled, attack at will.
First attack, I had to deal with escorts before and after attack. Submerged/depth charged for approx. an hour. Believe escorts had to go after rest of the pack at that time, though not sure.
Second and third attack, they were busy with the rest of the pack. Had convoy all to myself.

Out of a 15 or so ship convoy, only three left at attack's end. Two tankers and a cargo.
I bagged six for 42k tons during three separate surface attacks; two ships each attack.
Three medium cargos, two cargo steamers, one Arandona Liner.

Calm seas, 4m/s winds, clear night. Fired from 2k to 3.5k range, (hit the liner at 3.5k) 90 aob, decks awash 1-2 knots. Three torpedoes failed to hit.
Two topside torpedoes left. Broke contact with the rest of the "convoy" to reload these once daybreak arrives and if the seas remain calm.
