Has someone the book: "RAF Bomber Command Losses: Roll of Honour, 1939-1947" I would like to know if they are in there, it seems like a bomber loss to me.
I found the following text for 58 SQN RAF:
Based at St.Eval with Halifax
In April, 1942, No. 58 Squadron was transferred to Coastal Command and during the remainder of the war, as a general reconnaissance unit (flying Halifaxes from 1943 onwards), took a considerable toll of enemy surface vessels, sank five U-boats and shared in the destruction of two others.
An interesting page in this context of Halifaxes:
