Horse-drawn water cart stuck in the mud, St. Eloi, 1917.

Horse-drawn water cart stuck in the mud, St. Eloi, 11 August 1917. This photograph was taken during the Battle of Passchendaele (or Third Battle of Ypres). British soldiers try to rescue a water cart and its accompanying horse that have become stuck in mud after coming off the edge of a brushwood track. Shelling and heavy rain reduced much of the ground in the Ypres salient to a quagmire and made transporting supplies very difficult. Lantern slide, World War One, Western Front (1914-1918), 1917. From a box of 80 lantern slides.
