It's the 98th anniversary of the WW1 battle of Vimy Ridge. I have linked to a very interesting documentary video about the battle. It was a pivotal victory for the Allies and one of the events that helped form the identity of Canada as a young country. For anyone interested in Military history this is a fascinating event.
I find that WW1 has been somewhat forgotten. The huge casualty figures from that war are staggering. Previous to the Canadian assault on Vimy, which cost 3600 Canadian lives over 4 days, some 200,000 British and French troops had perished trying to get control of the ridge from the Germans.
