Convoy QP 13, groping its way through poor visibility conditions, blunders into a British minefield in Denmark Strait. U.S. freighter Richard Henry Lee is damaged but suffers no casualties among her 34-man crew and 9-man Armed Guard. Freighter Massmar fouls two mines and sinks; 17 of the ship's 36-man crew, and 5 of her 9-man Armed Guard, perish, as do 26 (22 merchant seamen and four Armed Guard sailors) of the 45 passengers she is carrying--survivors of the freighter Alamar (sunk in convoy PQ 16). Free French corvette Roselys rescues survivors. Freighter Hybert fouls a mine and is abandoned; as all hands (39-man crew, 11-man Armed Guard, and 26 passengers from the sunken Syros) abandon ship, the merchantman drifts into a second mine. British armed trawler HMS Lady Madeleine and Roselys rescue the survivors. Freighter John Randolph fouls two mines and breaks in two; 5 of the 38-man crew perish in the incident, but none of the 12 passengers or the 12-man Armed Guard are lost. Other ships in QP 13 rescue the survivors. The ship's bow section is recovered and salvaged, the stern section sinks. Freighter Heffron fouls two mines and is abandoned; one crewman dies in the abandonment. Roselys rescues the 36 crewmen, two Navy signalmen and 23 passengers. Heffron sinks very early the next morning.
