Canada’s national broadcaster CBC has put up some great new pages on its website about the Dams Raid. It features an interview with Fred Sutherland, looking fit and well in his home in Alberta, and giving his insights into the attacks on both the Möhne and Eder Dams. The news piece about Fred is here, but the more interesting stuff is here, with several more clips from the interview, some historical pieces of audio and much more well-researched information. Make sure you go through all the clips. You’ll be glad you did.

Fred Sutherland was Canadian, and was a forestry superintendent in Alberta from the mid-60s until his retirement. He never lived in England except during his time in service during the war. You must have known someone else.
