Attacks on this boat and other events

7 Sep 1943
The depth charge attack on 7 Sept, 1943 in the Bay of Biscay northwest of Cape Ortegal, Spain, in position 43.36N, 10.13W, by a Canadian aircraft from RCAF Sqdn 407 is often credited with sinking U-669.

The target was actually U-584, which escaped unscathed.

10 Oct 1943
One man was lost overboard in the mid Atlantic south of Iceland. (Thus only 52 men were aboard when the boat was sunk 3 weeks later, rather than 53 as given in most sources).

2 recorded attacks on this boat.

General notes on this boat

18 Jun 1942. Saboteur landings in America
The boat departed Brest, France for a very special patrol on 25 May, 1942. On 18 June, after crossing the Atlantic (submerged by day, surfaced at night) they landed a saboteur team of 4 men on the shore just south of Jacksonville, Florida. This was one of two such teams that landed within a week of each other on the US east coast; the other team came aboard U-202. They were to be the first of many such planned operations. The boat then returned safely to Brest on 22 July.

Men lost from the boat

31 Dec 1941
A lookout broke his arm during heavy weather in the Arctic.

10 Oct 1943
One man was lost overboard in the mid Atlantic south of Iceland. (Thus only 52 men were aboard when the boat was sunk 3 weeks later, rather than 53 as given in most sources).
