Sixty-three ships departed Liverpool 11 February 1943 and were met the following day by Mid-Ocean Escort Force Group A-3 consisting of the USCG Treasury Class Cutters ''Campbell'' and ''Spencer'' and the Flower class corvettes ''Dianthus'', ''Chilliwack'', ''Rosthern'', ''Trillium'' and ''Dauphin''. ==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〕 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Convoy ON 166」の詳細全文を読む スポンサード リンク 翻訳と辞書 : 翻訳のためのインターネットリソース Copyright(C) kotoba.ne.jp 1997-2016.
