The late James A W Deacon, Superintendent of Lights in the Hong Kong Government Marine Department, told me they tried unsuccessfully to find a place for timing ships over a measured sea mile on the south side of Hong Kong Island. Eventually such a \"course\" was, it is understood, set up at Tseung Kwan O (Junk Bay), in the eastern New Territories. It seems unlikely that the two Obelisks at Tai Tam were ever used for timing ships because of their rather 'tucked away' positions. There is also no evidence of there ever having been a second pair of beacons in the vicinity.\n\nAre there other possible uses for the two Tai Tam Obelisks? I was informed firstly in the late 1970s by a master mariner and senior civil servant in the Government Marine Department, that a Royal Navy Officer, who had served in Hong Kong before World War Two, had told him that the two Obelisks had been used when submarines submerged during tests. This practice came into being (so it was said) because of the loss of HM Submarine Thetis, on 1 June 1939, on its maiden dive with the loss of 99 sailors and civilians. A diver who went down to try to effect a rescue was also lost. Only four occupants managed to escape from the submarine using the Davis Escape Apparatus. The Royal Navy Officer told the senior Marine Department Officer that submarines were sent to Tai Tam Bay, after repairs or refits in the old Royal Naval Dockyard. At Tai Tam they could dive to periscope depth, in line between the two Obelisks. Then, if anything were to go wrong, the submarine could be traced and the crew rescued hopefully relatively quickly. The now retired Marine Department member of staff acknowledges that he never had material in writing to support this statement but he believes the information was given to him in good faith.\n\nWhen this information was put to Guy Clarabutt, who served in Royal Navy submarines in Hong Kong before World War Two, he said he had never heard of such a practice (Sinclair, 2000). Neither could he remember the two Obelisks at Tai Tam (Waters, 2000). I spoke to a young British naval officer stationed at HMS Tamar, on Hong Kong Island, in 1995. He felt that such a practice was highly unlikely. In 1997, however, I raised the same question with Commodore PJ Melson CBE, Chief of Staff and Deputy to Commander British Forces. He, as",

Fortunately the weather was good and sea calm. Already in attendance was the heavy cruiser CUMBERLAND, Captain L.F. Potter, who had lowered several of his boats to patrol for possible survivors. Two men had come to the surface prior to the arrival of HERMES. After anchoring, four boats from our ship were sent to augment the patrol over the scene of the disaster. Happily another four men came to the surface though sadly subsequently one died. The five living survivors were taken onboard HERMES to receive medical care and attention.\n\nHalf an hour later, 1530 hours by now, a diving boat was sent across from HERMES and some ten minutes later the first diver commenced his descent towards the position of POSEIDON on the sea bed. The sea temperature was 63 deg. F so bearable for those fortunate enough to be able to use the D.S.E.A. (Davis Submerged Escape Apparatus) within the stricken vessel.\n\nThat evening HERMES burned her searchlights over the position of the wreck and her motor boat commenced sweeping in order to establish the precise position of the sunken boat.\n\nLater in the evening MEDWAY (Captain H.R. Marrack, DSC), the Station submarine depot ship, arrived and anchored nearby. Also she assumed the position as guard ship. As will be imagined over the course of the next few days several more of H.M. Ships arrived and anchored in the vicinity. During the morning of the 13th these included the C. in C., Admiral Sir Howard Kelly, in SUFFOLK.\n\nMeanwhile the position of the wreck had been established exactly and diving parties were being sent down regularly, many of these parties being provided by our ship. Using a kedge anchor supplied by HERMES the tug ST. BREOCK was able to position herself directly over the wreck so assisting direct descent by these divers.\n\nIn the interim the U.S. Navy sent their specialised submarine salvage vessel to the scene, U.S.S. PIGEON ASR-6, which arrived during the late afternoon on the 11th.\n\nSadly it was established rather quickly that the extent of the damage",
