Battle of Ypres

The Battle of Ypres was during the First World War, in the general area of the Belgian city of Ypres, where the German and the Allied armies (Belgian, French, British Expeditionary Force (B.E.F.) and Canadian Expeditionary Force (C.E.F.)) clashed. There were hundreds of thousands of casualties. The term "Battle of Ypres" could mean all the fighting that occurred in that area. But the "Battle of Ypres" could refer more specifically to any one of five battles which have been separately identified and named (and which themselves can be subdivided into smaller named battles).
