At the beginning it was considered as a simple "frostbite" and troublesome for the military physicians who did know know how to cure this supposedly dermatological disease. More than 200 papers were published about the Trench Foot and the numerous individual inventions to protect the soldier's foot from mud, rain, cold and compression. As this issue is found in most testimonies of the fighters that proves it was a real and further suffering in the trenches.
