 :I don't know if that's true or not. The numbers of horses lost by many countries was not well tracked during the war. Britain lost almost half a million horses, or one horse for every two men lost. In writing Horses in World War I, I was unable to find solid statistics for how many horses were lost overall. The US sent over a million horses overseas during the war, with only about 200 returning to the US, and Australia shipped over 135,000 overseas, with only one returning. However, not all of these horses were killed in the war - some were slaughtered afterwards and some were sold to local populations. The Brooke Hospital for Animals was formed after the war in response to a young British woman seeing the neglect and abuse many British horses was facing after being sold in Egypt rather than being taken back to Britain. I still haven't seen the movie, however - my schedule keeps not allowing it.
