An old work by Hoyt, The U-Boat Wars, says in ‘42 the allies lost a million tons more than they built, but that took into account losses from all causes not just u-boats. Blair’s vol. 2 indicates Eisbar late in ‘42 was one of the most successful, if not the most successful operation. The Germans by 1943 may have stood no chance of sinking more tonnage than the allies could build, but if their IXs, and occasionally VIIs, had maintained radio silence while transiting to patrol areas, in remote areas, they would’ve continued to bag enough shipping to remain an important factor. They should’ve assumed the allies had made progress reading their mail just like b-deinst had reading allied mail.
