BX convoys

Declaration of war on 8 December 1941 removed United States neutrality assertions which had previously protected trade shipping in the Western Atlantic.

Although the United States was slow to convoy coastal shipping, the Royal Canadian Navy established the WLEF in February 1942.

[2] WLEF escorted the first BX convoy from Saint John, New Brunswick, on 21 March 1942 and reached Halifax the following day.

[1] The Mystic Steamship Company's collier USS Stephen R. Jones was grounded and sank in the Cape Cod Canal on June 28, 1942.

Temporary closure of the canal interrupted the flow of coastal shipping from Long Island Sound.

U-1232 managed to survive ramming by the River-class frigate HMCS Ettrick and escaped in difficult ASDIC conditions off Halifax.
