KTB, U-105
10 September
02:10 Changed course to intercept fast-moving ship reported in EK12 on northerly course, to our SSE.
02:50 In DU78, while still dark and well short of expected interception point, suddenly shelled from starboard by two escorts heading to cut us off. Must be radar-equipped. Alarm!
Dived to 140m and turned in under approaching escorts. Then turned again and onto silent running.
03:10 Enemies making repeated depth charge attacks, but detonations are well astern and above. No damage so far.
03:30 Depth-charging continues. We frequently hear the enemy sound location apparatus in use against us.
Unable to shake them off, so descend to 180m while making frequent changes of course and - when the cans are on their way down or exploding - speed.
03:50 Enemy still circling above us but depth charging has stopped.
Intention – proceed on mean easterly course at creeping speed. If escorts still above us when battery charge becomes low, go to periscope depth and counterattack
with torpedoes.
