The U-boat poked up its double periscope three times, each time submerging as she saw the patrol ship's guns turned toward her. She could not launch a torpedo with any success in that raging sea; neither could the Remlik drop a depth-bomb on her, as the Remlik could make only two knots against the gale and a bursting depth-charge might damage her as much as it would the "sub." There they maneuvered like two tigers, unable to spring at each other. After a few minutes the submarine, which had never shown enough of herself for our gunners to plant a shell in her, finally submerged and stayed under. The Americans kept sailing over the locality, hoping she would reappear; but, not wanting to risk a gunfire contest, the "sub" had given up the fight.

Tossed about by that stormy sea, a more imminent danger threatened the Remlik. The waves breaking over the stern tore loose one of the huge depth-bombs. The box that held it fell overboard, but the bomb was hurled in the opposite direction. There it went, rolling around the deck, while the crew amidships watched it with the fascination of danger.
