On April 25, 1908, the American liner St. Paul collided in the English Channel with the cruiser HMS Gladiator, killing 27 sailors.

Ten years later the St. Paul was chartered by the Navy to serve as a troopship in World War I. While in Brooklyn to be fitted out and repainted, she heeled over mysteriously in New York Harbor. Divers found that a port had been left open, flooding the lower boiler room.

No one ever discovered a reason for this, but it was noted that the St. Paul sank at 2:30 p.m. on April 25, 1918 — 10 years almost to the minute after she had sunk the Gladiator.
