I was cleaning up my desk, I am a "Pile" Filer, this weekend and found a DVD of my interview with CBC Newsworld taken on April 8 2007, a day before the 90th Anniversary.
I do my best to answer the question what did this battle mean for Canada. I hope you enjoy it.
Here is a link to my series about Vimy that has a mass of information that family members may find helpful.
