When the was wrecked on the ice-covered ledges off the island on February 3, 1918, Keeper Jennings and his assistants made four attempts to shoot a rope to the doomed ship but each time the rope parted. Jennings brought the lighthouse dory to the shore, and, assisted by two naval reservists, pushed it over the ice and into the surf. Twenty-four men were clinging to the wreck in perilous positions when he reached it after a dangerous trip. Flinging a line aboard, they began the rescue of the half-frozen sailors, four times running the gauntlet of ice, rocks, and surf until all 24 men were saved. For this Jennings received a letter of commendation from Secretary Redfield.
