“U.S. Submarines awaiting Orders,” halftone reproduction, printed on a postal card, of a photograph of five submarines nested together prior to World War I. The three boats on the right are (from center to right): USS D-2 (Submarine # 18); USS D-1 (Submarine # 17); and USS D-3 (Submarine # 19). The two left are probably (in no order) USS E-1 (Submarine # 24) and USS E-2 (Submarine # 25). Courtesy of Commander Donald J. Robinson, USN (Medical Service Corps), 1973. NH 78926
