Allied aircraft searching for enemy submarines along Surinam and Guiana coasts according to the U.S. Joint Intelligence Committee. Daily summary dated 25 February 1942

An item reported that reconnaissance flights above the coasts of Surinam and French Guinea including interior rivers and inlets between the Maroni river and the Oyapock during the past two days showed no sign of enemy submarines, bases or depot ships. It was strongly believed that both coastlines offered no practicable refugee for submarines.
