Interesting bit on McCrae from Wikipedia entry:
From June 1, 1915 McCrae was ordered away from the artillery to set up No. 3 Canadian General Hospital at Dannes-Camiers near Boulogne-sur-Mer, northern France. C.L.C. Allinson reported that McCrae “most unmilitarily told [me] what he thought of being transferred to the medicals and being pulled away from his beloved guns. His last words to me were: ‘Allinson, all the goddamn doctors in the world will not win this bloody war: what we need is more and more fighting men.'”
