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).
