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.
