Ships sailing from Halifax were escorted by WLEF minesweeper Winnipeg and corvettes Arvida, Pictou, Lethbridge and Rosthern.

Ships sailing from Sydney were escorted by WLEF Isles-class trawlers Baffin and Miscou, and Norwegian King Haakon VII.

The four warships from Halifax were detached when Mid-Ocean Escort Force group C5 River-class frigate Dunver and corvettes Dauphin, Wetaskiwin, New Westminster, Hespeler, Algoma, and Long Branch assumed responsibility for the convoy on 24 July.

One ship from the convoy waited in Loch Ewe to carry supplies to the United States garrison in Iceland; nine ships waited in the Firth of Clyde until convoy JW 59 formed to carry war materials to the Soviet Union; and 46 waited at Oban until channel ports were ready for them to offload food, fuel, and ammunition for Allied armies moving east from France, and trucks, jeeps, half-tracks, and locomotives to move those supplies to the front.

The following list describes the British, American, Norwegian, Greek, Dutch, Panamanian, Polish, Yugoslavian, French, and Swedish ships of this convoy and the cargoes they were transporting.
