2794. Captain Leigh returned from two weeks work with listening division in Channel. His reports very favourable to American devices. All American equipment used throughout the test without damage and without necessity using spare parts. All English Fish hydrophones were out of commission before end of period of operations. Detection by American devices superior to that by English devices. The maximum possible number of submarine chasers equipped with listening devices and manned by personnel trained for this work should be placed in service in war zone without delay. This is a matter of the highest importance warranting extraordinary effort. Admiralty attitude toward listening operations not entirely satisfactory, as some lukewarmness is exhibited and indisposition to perceive superiority of American devices over the Fish Hydrophone. This feeling not shared by officers at sea directly charged with work, but in view of existence in Admiralty I deem it most important that Captain Leigh remain here to inject the necessary energy into the operations, and I have therefore directed him, Lieutenant W.R. Carter, enlisted personnel, and civilian experts Scott and Nelson, to remain. Ensign W.W. Welch and civilian experts Eveleth and Collins will return to United States at once. Scott and Nelson will return within a month. I earnestly request that the Department insist on the most energetic action in the matter of dispatching the one hundred and ten footers to this side, allowing no difficulties to stand in the way.
