The 100 Days of World War I

Further to this post, David Frum quotes from the book:

In those 100 days, Canadian forces spearheaded the defeat of almost one-quarter of the entire German army remaining on the Western front, 47 out of 200 divisions. Add in the Australian/New Zealand forces, and the two Dominions together engaged some 40% of the German army. Over those three months, the Canadians suffered more than 45,000 casualties, killed and wounded – or about as many as in the whole year from D-Day to VE-Day in World War II.
