VERDAMMT! VERDAMMT! NOCHMAL!
said the Kommandant...
...and ordered the Funkmaat to report this...
Only few hours later, U-Boot was AGAIN taken by surprise in dense fog by a US Somers DD approaching out of "nowhere" with 35kn. Again no radar-warning!
Sunk it with 1 magnetic.
Radar not functional! Resuming patrol.
