20 Incredible Pictures Of Brave Animals On The Battlefields Of World War I

Aside from the human carnage of the First World War, animals were also recruited into military service performing a variety of tasks from carrying messages to pulling heavy artillery. Some acted as mascots for regiments, while other simply strayed across the bloodshed and were adopted by soldiers to help boost morale amidst the depravity and death of the Western Front. Many died in service, faithfully carrying out their duties amid the shells, bullets and the gas. Thanks to photos collected by the Great War Primary Documents Archive, we celebrate the brave animals of WWI, many of who never came home.
