Rudolf James Rose EM3 – December 17, 1927 – USS S-4 (SS-109) Was conducting Speed and Maneuverability testing off Provincetown, Massachusetts when it sank in 110 feet of water, after collision with USCG USS Paulding, which at 18 knots was chasing Rum Runners. Paulding spotted the S-4 too late and cut into S-4’s Hull in two places. Flooding in the battery well released chlorine gas which reached the control room because the ventilation valve was jammed open by a curtain. Survivors retreated into the motor room. In the passing hours a member of the local Coast Guard station secured a line to the sub with a grappling hook. Despite rescue attempts, all perished. Thirty-Four were in the engineering spaces, from the chlorine gas that followed them there. An additional 6 dead were in the forward torpedo room from lack of air. The S-4 was later raised and was used to develop submarine rescue procedures including use of a diving bell and the Momsen Lung. Rudolph James Rose was from Sandpoint, Idaho
