Having left Murmansk, on 27 June 1942, Convoy QP-13 encountered fog on 5 July 1942, north west of Iceland. Due to the overcast weather and poor visibility, about one mi (1.6 km), Commander Cubison, aboard the escort ship HMS Niger, ordered the convoy to form up in two columns, from five, to pass between Straumnes and the Northern Barrage minefield. At 20:00 Commander Cubison had estimated his location at 66°45′N 22°22′W and suggested that the convoy alter course to 222°. At 22:00 Niger mistook what was later identified as an iceberg for Iceland's North Cape, at a bearing of 150° and one mile range. Cubison ordered the convoy to change course to 270°. At 22:40 Niger exploded and sank with a heavy loss of life, this included Commander Cubison. The convoy had entered the minefield at this time and the merchant ships SS Heffron, SS Hybert, SS Massmar, and SS Rodina struck mines and were sunk, John Randolph and SS Exterminator were seriously damaged. The forepart was salved but broke tow on 1 September 1952 and was wrecked at Torrisdale Bay, Sutherland, Scotland, on 5 September.^[6][7][8]
