The devastation that a single shell could wreak is bleakly summarised in this drawing by Frank Dadd, entitled ?Wiped out by a single shell: a holocaust of horses in the danger zone.? The image was reproduced in The Graphic in June 1917, accompanied by this extract from a machine gun officer?s diary, ?A little way up the road we came upon a General Service waggon, with a team of horses lying dead beside it. A shell had exploded in the midst of them, killing the lot at once. The drivers, who were about to mount, escaped unhurt. A little way in front another horse lay across the road badly wounded, and had to be shot by one of the men. The waggon was returning after taking supplies to the trenches.?
