I found a fairliy good start at a website dedicated to the Dortmund-Ems and Mittelland Canal Raids 1940-1945. See: http://bomberhistory.co.uk/canal_raids 617 Squadron made several famous raids on the canals: http://www.dambusters.org.uk/after-the-dams/raids/dortmund/ (I am named after Fred Sutherland of the Dambusters) http://www.dambusters.org.uk I was surprized that I did not find a thread already dedicated to this topic here ... or on our sister site http://ww2talk.com/ Any further information would be greatly appreciated.
