Australian officers, blown into the air by an accidental explosion, fall in the river amid the splinters of their wrecked boat; ca. 1942
FromĀ LIFE (June 15th, 1942):
During night maneuvers in New South Wales a few weeks ago, Australian soldiers were landing at the edge of a dam when a charge of gelignite, employed to lend realism to their operation, unexpectedly exploded beneath their boat. Amid splinters and spray the Aussies were hurled into the night. As they fell, a photographer 20 feet away snapped his shutter and caught the remarkable picture opposite. The soldiers suffered only bruises and shock.
Australian soldiers blinded in a German gas attack at an aid station near Villers-Bretonneux, France; May 27, 1918.

The differences in their body language is really interesting. You have everything from just totally dejected to a couple guys who might as well just be laying out sunbathing for all the concern they’re displaying.
The Germans were using mustard gas at Villers-Bretonneux. A mild dose would result in the eyelids swelling up to the point where the casualty would be temporarily blinded, more severe exposure could damage their eyes to the point where they’d be blind permanently.
