The latrines was the name given to trench toilets. Soldiers designated specific areas to serve as the latrines. Soldiers dug pits anywhere from four to six feet in depth in which to relieve themselves, and while these holes were usually used as-is, some troops attempted to control the amount of flies attracted to waste by building wood boxes around the pits. The job of digging and then maintaining the latrines was so despised, these chores were often given to soldiers as punishment. The smell was equally as horrifying, and troops dealt with the odor by attempting to cover it with chloride of lime.
Unfortunately, choosing when to need the bathroom isn't often possible, especially for those suffering from diarrhea due to contaminated drinking water. Those unable to use the latrine often made use of buckets or empty food cans to relieve themselves. "If, for instance, you wanted to urinate and otherwise, there was an empty bully beef tin kept on the side of the hole," one British lieutenant recalled. "...You had to do it in front of all your men [and] then chuck the contents, but not the tin, over the back [of the trench]."
