World War 1, Europe France Passchendaele, 1917

During the three and a half months the Battle of Third Ypres (Passchendaele), just over fifty British and Commonwealth infantry divisions, and almost one hundred German ones were committed. It is therefore reasonable to say that about one and a half million men witnessed this battlefield first-hand. Total casualties at Passchendaele are estimated at 475,000; about 275,000 British and Commonwealth and about 200,000 German. 38,000 Australians, 15,654 Canadians and 5,300 New Zealanders fell there, either killed, wounded or missing. Especially for these smaller nations, Passchendaele was their most costly engagement of the war, indeed their entire military history.
