at a merchantman but missed. With one torpedo remaining in the bow tubes, she fired and hit the target abreast the foremast. When last seen, it was listing heavily to port and making for the Celebes shore. On 6 April, she fired a spread at a tanker; but the range was so close that they failed to arm. The submarine was then depth charged by escorts but eluded them and patrolled off Cape Mandar (in West Sulawesi) in the Makassar Strait. On 22 April, a destroyer's searchlight blinked to Sturgeon, and she went deep to avoid the subsequent two-hour depth charge attack. On 28 April, the submarine sailed for Australia. However, she interrupted her voyage on the night of 30 April in an attempt to rescue some Royal Australian and Royal Air Force personnel reported on an island at the entrance of Cilacap Harbor. A landing party under Lieutenant Chester W. Nimitz, Jr. entered the cove and examined it by searchlight but found only a deserted lean-to. She continued to Fremantle and arrived there on 7 May. Fourth patrol: June – July 1942 Sturgeon refitted and returned to sea, on 5 June, to patrol an area west of Manila. On 25 June, she caught up with a nine-ship convoy before daylight, and fired three torpedoes at the largest ship and heard explosions. After some 21 depth charges were dropped by the escorts, she managed to escape with only a few gauges broken. On 1 July, Sturgeon, captained by LT CMDR Wright, sank the 7,267-ton prisoner transport off the coast of Luzon. On 5 July, she scored hits on a tanker in a convoy northbound from Manila. Her patrol ended on 22 July when she arrived at Fremantle for refit. It was later discovered that Montevideo Maru had been carrying over a thousand Australian prisoners of wars and civilian internees from Rabaul New Guinea. 1,140 (including 88 Japanese crew) were killed while 18 survived. Some of the Japanese including the ship's captain made it to the Philippines but most, including the captain, were killed by local guerrillas. This loss of Australian lives is the worst maritime disaster in Australian history. Only one eyewitness account has ever emerged. After 60 years the sole surviving Japanese sailor described the "death cries" of trapped Australians going down with the ship while others sung Auld Lang Syne. Fifth patrol: September – October 1942 Sturgeon stood
