U-504
A week after Krech, U-boat ace “Fritz” Poske returned to the area on a similar pattern. Poske took U-504 from a point midway between Bermuda and Anegada on the 22nd of May and steamed straight for the Windward Passage, passing south of the Turks & Caicos Islands and north of the Mouchior Bank on the 25th and 26th and out of the area and into the Caribbean on the 27th of May 1942.
Outside the Bahamas area he then sank six ships of 19,418 tons, all off the southwest coast of Cuba and in the Yucatan Channel: Allisteron 29 May, Rosenborg, the Dutch passenger ship Crijnssen, freighter American, and the Latvian Regent between the 8th and 14th of June. Thereafter he proceeded to the Anegada Passage, leaving the area via that route between the 20th and 21st of May after a highly effective patrol, which lasted from 2 May to 7 July, 1942.
As mentioned earlier Poske was highly rewarded U-boat commander and was awarded the Knights Cross on 6th November 1942, less than four months following the conclusion of this patrol.
