Lucky escape from a mine
On his return from her third and last patrol on 14 April 1943 KrvKpt. Rolf Rüggeberg's U-513 was met by one of her sister type IX boats, Kptlt Hans Möglich's U-526, as they waited for a minesweeper to escort them to base at Lorient, France. Being the senior officer, Rüggeberg should have been first in line behind the minesweeper, but Möglich, eager to enter port after 63 days at sea, rushed ahead of Rüggeberg. One mile from port, the minesweeper had left the boats for them to continue to 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 twelve survived, nine of them wounded. U-513 moored unscathed amid frantic rescue operations. (Blair, 1998)
From June 1943 until the end of war FrgKpt. Rüggeberg commanded the 13th Flotilla at Trondheim, Norway.
Rolf Rüggeberg was a Naval Attache in London in the early 1960s.
