Looking further along the west wall. Perhaps it's time to talk about the moat!

Fort Mifflin is one of only nine American starforts fortunate enough to be surrounded by a moat. In addition to its obvious defensive role, a moat also served as a source of fresh water and sewage disposal for the fort's garrison...sometimes. If it's done correctly, fresh water flows through the moat, taking with it all of the poop that a garrison of healthy young men can produce as it exits into the nearby water source required for such an endeavor. Successfully causing this was trickier than it may seem, however, and often a fort's garrison became much more familiar with its own effluence than it may have wished.
