Undertaking this patrol prior to the launching of our first large-scale offensive in the Pacific, Captain Cromwell, alone of the entire Task Group, possessed secret intelligence information of our submarine strategy and tactics, scheduled Fleet movements and specific attack plans. Constantly vigilant and precise in carrying out his secret orders, he moved his underseas flotilla inexorably forward despite savage opposition and established a line of submarines to southeastward of the main Japanese stronghold at Truk.
Two demolition charges were fired with 10-minute fuze, and boarding party hurried on board. At this moment, securing line broke, schooner started to drift away and the last two of the boarding party, including S/Lieutenant Fritz carrying charts, books and signals, had to jump overboard and swim a few yards. Of course, none of the panicky-sighted targets materialised, but now the fuze was set and the chance of a considerable prize was lost.
