History of United States Naval Operations in World War II
"Late in 1943 a number of Japanese I-boats entered the Indian Ocean and conducted a blitz against Allied shipping which was marked by instances of sadistic cruelty. British S.S. Daisy Moller, torpedoed by one of them on 14Dec43 in mid-ocean, lost 55 men out of 127 passengers and crew by the ramming and machine-gunning of rafts and lifeboats. The crew of S.S. British Chivalry met the same fate.
"Dockage and repair facilities were being improved at Penang, and three Italian submarines which were seized by the Japanese when Italy surrendered in September, were there refitted and manned by German officers and mixed crews. At the turn of the year, these and the "Monsun" boats1 started to leave Penang. Six of them did a great deal of damage to Allied merchantmen and "country ships" along the Aden-Bombay route and elsewhere in the Indian Ocean, assisting the Japanese I-boats to sink 184,122 tons of Allied and neutral shipping in the first three months of 1944. Several victims were Liberty ships, one of which, S.S. Richard Hovey had a most devastating experience on 29 March 1944. The Japanese submarine, after fatally torpedoing the vessel, moved to within a thousand yards of its lifeboats and, as the Naval Armed Guard officer recalled, opened fire on the survivors: -
. . . "Richard Hovey was the last merchantman to be
sunk in the Indian Ocean for several months."
