The Unknown Soldier who took this picture (approximately 1909) wrote a brief but cryptic hand written description of this improbable event:
This beast hid in the sandbags. Some believed that it was responsible for stacking the sandbags at odd places in the trenches. This thing would attack sentries on the night shift when they were alone. It is pure luck that I managed to take this picture. It lunged out, and ate/crushed 2/3 of Private Jenson. The face area started to suction its tongue with teeth back into itself. I think that the cannons and explosions of this unholy war may have wakened this foul ambush body-snapper from the bowels of hell itself. May god have mercy on our souls!
