As a teen age boy I watched this on memorial day when it was originally broadcast. As a Canadian I was deeply moved by the waste of young lives. It haunted me for years. Memories of this documentary fuelled be later to read every book I could find on the subject.
I especially recommend James Leasor's "Green Beach" "Unauthorized Action" by Brian Loring Villa, Lucien Dumais' "Un Canadien Français à Dieppe", "the Shame and the Glory" by Terence Robertson, "Tragedy to Triumph" by Denis Whittaker.
The film makers combine interviews with veterans with archival footage and beautiful and evocative paintings depicting the events. I was especially impressed with the art work. A superb overview.
