World War I Casualties

Euston Road Cemetery, Colincamps, France. These are British and Commonwealth casualties

There are many sources that list casualties figures from the Great War. One particularly good reference, with commentary and analysis, is: Michael Clodfelter, Warfare and Armed Conflicts: A Statistical Reference to Casualty and Other Figures, 1618-1991 (London: McFarland & Company, 1992. 2 vols.). Because of the enormity of the numbers involved, in many cases the figures for the separate countries are often only best guesses or rough approximations. A contemporay calculation was done for Current History by Walter Littlefield, "War Casualties of All Nations" (February 1919) resulting in a total of about 36 million casualties (*.pdf file).
