My first introduction to this was a fictional novel by John Irving called "Setting Free the Bears". I read it many years ago so the details are fuzzy but the rivalries between the ethnic groups in Yugoslavia still haunts me. Then again it might have all been fiction.

How about some details on Canadian war production. Where the planes are made. Where the tanks, trucks and munitions are made. How much of it made it to the front lines and who used it.
