The modern RN vessels which accompanied Arctic convoys, for example, had no problems when operating at reduced speed. Nor had those US boats which had briefly accompanied North Atlantic convoys in early 1942. Moreover, what actions did the US Atlantic Fleet undertake in early 1942 which required massive destroyer escort numbers? Yes, Coast Guard cutters, DEs, or corvettes and sloops were more suited, but as these were not available, did that really justify allowing the mass slaughter of freighters in large numbers? Armed merchantmen had very little hope of protecting themselves from U-boats. Generally, the first warning the merchant ship had was went a torpedo exploded. 'Note that the Royal Canadian Navy immediately organized convoys, despite the lack of escorts, and this appears to have cut sinkings of the Canadian coast from 37 in January and February to 11 in March and April.' Indeed. Isn't that the point I am making? The RCN itself noted that U-Boats preferred to hunt further south, in a convoy free environment. In April, the RN & RCN detached 24 escorts from their own resources to support US efforts, but still convoys were not established. The British then set up their own convoys between Halifax & Trinidad, later Aruba. Between May and August, they escorted 14 convoys, totalling 76 tankers, withouit a single loss. Incidentally, if I am wrong about the authority of the US War Shipping Administration, how was it the Kentucky and Ohio, two fast tankers, were transferred to the British Ministry of War Transport for service in the Mediterranean in early-mid 1942?

  25.  @nickdanger3802  Never a good idea to accept uncritically an RAF source where the Battle of the Atlantic is concerned. To use an accurate, Naval, source :- 'Total shipping losses of the Allied and neutral nations were about 456,000 gross tons a month during the period July 1940 to March, 1941, more than 60 per cent higher than during the first period. Meanwhile the building rate had increased only slightly to about 114,000 gross tons a month, making the net loss of shipping about 342,000 gross tons a month. Total shipping available had decreased from about 38,000,000 gross tons at the start of the second period to about 35,000,000 gross tons at the end of the second period. Of the 456,000 gross tons of shipping lost monthly, about 404,000 gross tons were lost by enemy action. U-boats accounted for 42 ships of 224,000 gross tons a month (55 per cent of the total tonnage lost by enemy action), more than twice the monthly tonnage sunk by U-boats during the first period. Monthly shipping losses due to enemy surface craft jumped to 87,000 gross tons (22 per cent) and those due to enemy aircraft increased to 61,000 gross tons (15 per cent). Monthly losses due to mines dropped from second place in the first period to only 27,000 gross tons (7 per cent), with other and unknown causes accounting for the other 1 per cent of the total losses due to enemy action. There is no doubt that the U-boats had inflicted a serious defeat on the Allies in the Battle of the Atlantic during the second period, but the situation was beginning to look more promising toward the end of this period. One favorable element was the increasing number of antisubmarine ships and aircraft becoming available for convoy escorts as the threat of the invasion of England was decreasing. The number of antisubmarine ships suitable for ocean escort (i.e., destroyers and patrol craft such as sloops, frigates, corvettes) had increased from about 235 at the start of this period to about 375 (includes 240 destroyers) at the end of the period. Important factors in this increase were the coming into service of the new corvette and also the transfer of the 50 old Town class destroyers from the United States to England from September 1940. These destroyers were equipped with U. S. echo-ranging gear, called sonar, which was similar in principle to the British Asdic.' Thus, although the figures are largely accurate, the conclusions are incomplete, in that, losses in terms of gross tonnage available had decreased by less than 8%, at a time when the first 'Happy Time' was in full swing. Evasive, or Diversionary, Routing didn't apply during the period June-December, 1940. It relied upon widespread use of HF/DF sites on ships and shore bases, combined with successes in breaking German Naval Enigma, both of which post-dated that period. How, by the way, is any of this relevant to PQ17 or Paukenschlag?
