MV Mamutu

From Wikipedia, the free encyclopedia

"MV Mamutu," was an Australian Merchant ship, built at Hong Kong in 1938 was of 300 tons gross. length 113ft. and beam 25ft. She operated on the Inter Island trade for Burns Philp & Co. and at the outbreak of war she was engaged in the evacuation of civilians ahead of the Japanese Forces.

With the onset of war Mamutu served as a Stores Issuing Ship for ships of the Royal Australian Navy during 1941, returning to customary re-supply duty in January 1942. On the 7 August she was sunk by enemy action in the Gulf of Papua near Murray Island, Torres Strait, with the loss of 114 lives. Twenty-seven persons were thought to have survived by drifting to the coast on air-delivered rafts, while one was brought back to Port Moresby by a Royal Australian Air Force rescue plane. The attack location, given by British Admiralty records, was 09.11S by 144.12E

The following recounting of Mamutu's loss is drawn from the book "Battle Surface- Japan's Submarine War Against Australia 1942-1944" by David Jenkins. Published by Random House Australia 1992:- reference

The submarine trailing Mamutu was a RO-33 class submarine under the command of Lieutenant Commander Shigeshi Kuriyama. R.O.33 had a surface speed of 19 knots and was closing fast, as she drew near Kuriyama ordered his crew to man the 3.25inch gun mounted forward of the conning tower. At 300 metres he gave the order to fire. The first shell ripped into the radio room killing Furbank, the second shot carried away the bridge killing Captain J. McEachern. Other shells tore into the hull. Within minutes Mamutu was a scene of carnage with dead and dying littering the decks. Kuriyama then ordered his gunners to open fire with 13 mm gunfire as survivors struggled in the water, men women and children. He then retired leaving Mamutu a sinking hull and most of her complement dead.

There was only 28 survivors from the total complement of 120 persons. One man, a European Engineer, Bill Griffin, escaped death at the hands of the ruthless machine gunners by pretending to be dead.

A B-17 Flying Fortress search aircraft dropped life rafts to the struggling survivors who eventually made it to shore. The Army signal ship "MV Reliance" which was used by the Coast Watchers, was sent from Murray Island to try to pick up the survivors. They were unable to locate the survivors.

On 29 August 1942, RO-33 torpedoed the Burns Philp ship "Malaita" (3,310 tons) as she left Port Moresby. "Malaita" was being escorted by the destroyer HMAS Arunta (1870 tons). While "Malaita" was towed back to Port Moresby, Commander J.C. Morrow, the captain of HMAS Arunta made an asdic contact on RO-33. The Japanese submarine was sunk 10miles SE of Port Moresby (09-36S, 147-06E) with all hands lost as a result of a series of depth charge attacks by HMAS Arunta.
