Hello everyone,
A Canadian television producer, History Channel, has made a new documentary about the Battle of the Mace, hosted by Prof. David O'Keefe. He did a show in 2006 about the battle at Verrieres Ridge. The new show includes research into previously secret war records to investigate why the Falaise Gap was not closed sooner, and why the Poles were stranded on Hill 262 for three days.
I found a link to a site that shows the video: http://www.history.ca/video/ Scroll to the bottom of the page and click on "Secret War Files: The Battle of The Mace". I hope it works outside Canada.
I am also trying to contact Prof. O'Keefe to find out whether the show is available on dvd.
