Dead Wake: The Last Crossing of the Lusitania

by Erik Larson

These fish and their residual odors, however, could only have worsened the single most unpleasant aspect of U-boat life: the air within the boat. First there was the basal reek of three dozen men who never bathed, wore leather clothes that did not breathe, and shared one small lavatory. The toilet from time to time imparted to the boat the scent of a cholera hospital and could be flushed only when the U-boat was on the surface or at shallow depths, lest the undersea pressure blow material back into the vessel. This tended to happen to novice officers and crew, and was called a “U-boat baptism.” The odor of diesel fuel infiltrated all corners of the boat, ensuring that every cup of cocoa and piece of bread tasted of oil. Then came the fragrances that emanated from the kitchen long after meals were cooked, most notably that close cousin to male body odor, day-old fried onions.
