War Horses in Gas Masks 1918
Gas was a weapon that will be forever associated with the Great War. First used at Ypres in April 1915, it caused many casualties among the front line troops. But gas did not just linger on the battlefield – it drifted. And in drifting it moved into areas that were used to bring up supplies and ammunition, and as the war progressed, these areas became often as much targeted as the front line.
As the majority of transport in every army during WW1 was horse or mule transport, then these animals became as much affected by the gas as their human masters. Just as gas masks were developed for the troops, masks were equally introduced for horses; this image shows a British soldier wearing a Small Box Respirator, introduced in 1916, checking the gas masks of two horses pulling a service wagon. Gas warfare was a bad enough experience for humans; one can only wonder at the experience the horses went through when poison gas enveloped the battlefield.
