Lucky escape from a mine
On his return from the third and last patrol on 14 April 1943 KrvKpt. Rüggeberg's U-513 was met by one of its sister-boats, the U-526 commanded by the young Kptlt. Hans Möglich, as they waited for the minesweeper to escort them to base at Lorient, France. Being the senior officer Rüggeberg should have been first in line after the minesweeper but Möglich, eager to enter port after 63 days at sea, rushed ahead of Rüggebergs boat. One mile from the dock the minesweeper left the boats who headed to the dock when U-526 hit a newly laid British mine and exploded in a huge blast, ripping the boat in two. 42 died, including Möglich, and only 12 survived, 9 of them wounded. U-513 moored safely amid frantic rescue operations (Blair, 1998).
