Vague intelligence about German submarine intentions in the Atlantic according to the U.S. Joint Intelligence Committee. Daily summary dated 11 January 1942

An item reported that according to the J.I.C. the u-boat positions in the Atlantic Theatre were somewhat vague despite intelligence pointing out ultimate heavy concentrations east and southeast of Newfoundland. Weather conditions seemed to prevent submarine activities on the northern route but it was the prime area for Germans to start their offensive instead of an all-out operation against convoy traffic.
