Convoy HX 212
Convoy HX 212 was the 212th of the numbered series of World War II HX convoys of merchant ships from HalifaX to Liverpool.〔Hague p.127〕 The ships departed New York City on 18 October 1942〔Hague p.128〕 and were met on 23 October by Mid-Ocean Escort Force Group A-3 consisting of the USCG Treasury Class Cutter ''Campbell'', the destroyer ''Badger'' and the Flower class corvettes ''Dianthus'', ''Rosthern'', ''Trillium'', ''Dauphin'', ''Alberni'', ''Summerside'' and ''Ville de Quebec''. The first five escorts had worked together previously, but the last three corvettes were attached to the convoy only for passage to the eastern Atlantic in preparation for assignments on Operation Torch. ''Summerside'' was the only escort equipped with modern Type 271 centimeter-wavelength radar.〔Milner pp.175-177〕
==Background==
As western Atlantic coastal convoys brought an end to the second happy time, Admiral Karl Dönitz, the ''Befehlshaber der U-Boote'' (''BdU'') or commander in chief of U-Boats, shifted focus to the mid-Atlantic to avoid aircraft patrols. Although convoy routing was less predictable in the mid-ocean, Dönitz anticipated that the increased numbers of U-boats being produced would be able to effectively search for convoys with the advantage of intelligence gained through ''B-Dienst'' decryption of British Naval Cypher Number 3.〔Tarrant p.108〕 However, only 20 percent of the 180 trans-Atlantic convoys sailing from the end of July 1942 until the end of April 1943 lost ships to U-boat attack.〔Hague pp.132,137-138,161-162,164&181〕
