DescriptionA letter from the Naval Representative at the Australian High Commissioners Office in London, Captain Francis Haworth Booth, to Mrs Woodward summarising the official report on the disappearance of the submarine AE1 on 14 September, 1914. Mrs Woodward's husband, Frederick William Woodland, was an able seaman on board at the time. Captain Haworth concludes the letter with "The Vice Admiral commanding His Majesty's Australian Fleet expresses the opinion that AE1 made a practice dive and failed to return to the surface, and he states that 'he cannot account for her disappearance in any other way'". HistoryThe AE1 was put into service in September 1914 as part of the Australian Naval and Military Expeditionary Force into New Guinea in the attempt to eliminate German presence there and ensure their wireless communication stations were not able to be used by them. On September 14, HMA Submarine AE1 and HMAS PARRAMATTA were directed out into the St Georges channel around New Britain and New Ireland in attempts to locate any enemy ships that may still be in the area. Although seas were calm, it was noted that the day itself was hazy and by mid-afternoon visibility on the water was reduced to five nautical miles. At 1520 HMAS PARRAMATTA spotted AE1 off Bernard Point. However, by 2000 that night AE2 had not returned to Simpson Harbour as agreed. HMAS PARRAMATTA and HMAS YARRA started to search for her that night but no trace was found. The next morning the search was widened and now included HMAS ENCOUNTER and HMAS WARREGO. At the end of three days searching, which now also included a number of smaller vessels available to the Australians, the search was concluded with no trace or clue as to what had happened to AE1. In a report back to the Admiralty Vice Admiral Patey suggested that AE1 most likely had struck and an underwater reef and sunk in the deeper waters of the channel. In December 2017 a new search for Australia’s HMAS AE1, was undertaken by a collaborative team comprising researchers and specialists from the Silentworld Foundation, ANMM, Find AE1 Ltd., the Royal Australian Navy and Fugro, N.V. The search was successful and identified AE1’s final resting place off the Duke of York Islands in Papua New Guinea. In April 2018, further research was carried out at the site by the ANMM, Find AE1 Ltd. and Curtin University’s HIVE (Hub for Immersive Visualisation and eResearch) aboard R/V PETREL, a vessel owned by Microsoft co-founder Paul G. Allen and operated by Vulcan, Inc. Also on board was a Remotely-Operated Vehicle (ROV) and images relayed back to researchers aboard PETREL revealed vital clues to a sequence of events that led to AE1’s loss. For example, the submarine’s bow and stern torpedo tube caps were found to be either partially or fully open, and that this appears to have been an intentional act carried out on the surface. Why the caps were open, and whether they contributed in some manner to the loss will likely never be known. Similarly, the reason that a ventilation valve was partially open will probably never be known, but it is fair to say that it was one of the root causes of the submarine’s demise once it began to submerge on what would be its last dive. Despite efforts by the crew to recover—as evidenced by the positions of the submarine’s hydroplanes—AE1 was overwhelmed by the inflow of water through the ventilation valve and began to sink by the stern. At an unknown depth, the forward pressure hull partially imploded, killing the crew instantly. The submarine continued its fatal dive until it struck the seabed stern first at a shallow angle, breaking off the skeg and rudder. The hull then pitched forward, breaking AE1’s back and possibly snapping off all four hydroplane guards. This violent movement also affected the fin, which—likely already weakened structurally during the implosion—began to topple forward into the remnants of the control room. Going forward, the imagery and 3D model generated as a result of the 2018 investigations will prove critical in AE1’s ongoing interpretation, exhibition and management. SignificanceThe submarines AE1 and AE2 have a significant place in RAN history, not only as the first submarines built for the navy but also the role they played in Australia’s first engagements in World War 1. AE1 as part of the Australian Expeditionary Force to New Guinea and AE2 in her heroic mission through the Dardanelles and into the Sea of Marmora.

Crews of submarines were very much viewed as heroes, "That is why every man who joins the sub- marine service, officer and man, are among the pick of the navy, the bravest of brave. Though AE1 was not lost in action with the enemy, each man on board, from Lieutenant-Commander Besant down, ready to hazard his life in the dangerous work he had chosen in the Empire's vice “(Sydney Morning Herald, 21 September 1914).
