"Crash dive by Claude C. Vickrey" is a naval adventure short story written in the late 1920s. It portrays a submarine training exercise that turns into a perilous emergency, focusing on seamanship, technical failure, and the crew’s ingenuity under extreme pressure. A young submarine officer narrates his first crash dive, where a cascading series of small errors culminates in the chief forgetting to shut the main induction valve. Flooding drives the boat
to the bottom in mud at about one hundred thirty feet with the bow steeply down, trapping the crew and threatening them with dwindling air and chlorine gas from compromised batteries. Realizing they cannot pump out the water, the officers gamble on forcing the stern to the surface: they blow out fuel, oil, and fresh water, shift every movable weight forward, and work hand pumps in darkness as morale frays. After grueling hours they heel the submarine to roughly seventy-eight degrees, chisel through the exposed stern plating, and raise a makeshift distress flag. A Coast Guard destroyer spots the signal and rescues the exhausted men, capping the ordeal with the captain’s dry reply to a command query: “Position Vertical!” (This is an automatically generated summary.)
