The Lisbon Maru sailed from Hong Kong on 27 September 1942 en route to Shanghai and Japan. She was armed and carried, in addition to 1816 British POWs, 778 Japanese troops and a guard of 25 for the POWs. There was nothing that identified her as carrying POWs.

The British POWs were mostly drawn from The Royal Navy (379) ‘accommodated’ in No 1 Hold at the front of the ship, 2RS (373) and 1MX (366), with others from various cap badges to a total of 1077, ‘accommodated’ in No 2 Hold forward of the Bridge and the RA (380) ‘accommodated’ in No 3 Hold at the stern. The Senior British Officer on board was Lt Col HWM Stewart, CO 1MX, in No 2 hold. Conditions in all three holds were very crowded.

Just after 0700hrs on 1 October, in a position 6 miles off the Sing Pang Islands in the Chusan (now Zhousan) Archipelago off the coast of Chekiang Province (south of Shanghai), the Lisbon Maru was hit in the engine room, at the stern, by a torpedo fired from the US submarine USS Grouper. The engines stopped, the lights went out and those few POWs who were on deck were pushed back into the holds. The ship’s gun began firing. The POWs were kept in the partially closed holds throughout the day with no food, water or access to latrines. No blame has ever been, nor ever must be, attached to the USS Grouper. There was nothing that identified her as carrying POWs; there were a large number of Japanese troops on board; and she was armed. Everything that could be seen identified the Lisbon Maru as a legitimate target.

At 1700 hrs the 778 Japanese troops were taken off onto a Japanese destroyer and merchant ship which had arrived, leaving the British POWs, their guard of 25 and the 77 crew on board. In doing so they removed the ship’s four lifeboats and most, if not all, of the six life rafts ensuring that none would be available for any possible subsequent evacuation of the POWs. At about 2100 hrs, allegedly fearing the POWs could break out and overpower the guard, the Guard Commander ordered the ship’s Captain to fully close the hatches and batten them down with canvas. Conditions in all three holds deteriorated rapidly. In No 1 Hold two diphtheria patients died and in No 3 hold., nearest where the torpedo had struck, water was rising rapidly. The POWs manned the pumps; but because of the extreme heat and shortage of air some of them collapsed into the water and drowned.

By dawn on 2 October it was apparent that the ship was in imminent danger of sinking and soon afterwards the crew and all but five of the guards were taken off. At about 0900 hrs the ship gave a violent lurch and it was apparent that she could not last much longer. Lt Col Stewart ordered a Royal Scots officer, Lt Howell, to attempt to break out through the battened hatches. He succeeded in doing so and, after being shot at by the remaining Japanese guards, which led to two men being killed, reported to Col Stewart that the situation was desperate and that the ship was in imminent danger of sinking, but that he had seen an island some distance off. Col Stewart gave the order to leave the holds and a number of the POWs rushed on deck, plunged overboard and began swimming towards the island. The remaining guards began firing at them until the weight of numbers of POWs pouring onto the deck overpowered them and, probably, threw them overboard.

By good fortune the stern at this point became stuck on a sandbank leaving the forepart as far as the bridge sticking out of the water for about a further hour which gave sufficient time for all live men to climb or be assisted out of the holds. Many men did not have lifebelts and many could not swim. Between the ship and the islands were a number of Japanese auxiliary vessels and tugs, some of them surrounded by men in the water vainly asking to be picked up and, if they were, then pushed them back into the water; and the firing of shots could be heard. The Lisbon Maru finally sank at about 1045. At some stage the Japanese boats started to pick up those prisoners still alive in the water and who had not drifted past them towards the Islands.

Lt Howell, having been picked up by fishermen in a sampan, was among the first to reach the largest of the Islands and was able to explain to the villagers there that the heads bobbing about in the water were British prisoners and not Japanese. As a result the Chinese set off in junks and sampans to assist the survivors. They picked up a considerable number of exhausted swimmers while other villagers assisted those who had drifted or swum to the islands and helped them to land on the rocky shores. Some 200 survivors were assembled on the islands, where the villagers fed and clothed them from their own scanty supplies and treated them with great kindness until the Japanese landed in force on the following days and rounded up all but three of the prisoners. These three, all civilians who had been working in Hong Kong – two with the Royal Navy, were hidden by the village representative, who later arranged for their escape to Chungking.

Those picked up by the Japanese ships were collected together on the deck of a large gun boat where, exposed to the elements, some died of exposure and exhaustion before finally being landed south of Shanghai on 5 October.


Of the 1816 POWs who had left Hong Kong only 973 (including the three escapees) survived leaving 843 (46%) who were assumed to have been killed by the Japanese firing on them or drowned – many of the latter being non-swimmers, without life-jackets or other means of support, and some, it was reported, as the result of shark attack. Amongst The Royal Scots a total of 183 died, many more than the107 killed in the whole of the battle for Hong Kong. Relatively few of the POWs, only those who had died on board before she sank, would have gone down within the ship. The remains of the others will have been scattered in the surrounding seas.

Subsequently Lt Howell was awarded the MBE for his gallantry in breaking open the hold and Lt Norman Brownlow the same award for organising the evacuation of the ship and then, having reached the island himself, obtaining a small boat and rescuing men from the sea who were trying to reach and clamber ashore on the islands.

After the war a fund was organised amongst survivors in order that the proceeds might be sent to to the Sing Pang islanders as a token of gratitude. In February 1949 the Governor of Hong Kong presented to Mr WooTung-ling, the village representative who had hidden the three escapees, and other islanders a motor fishing launch and some monetary awards.

A memorial to those who had died was placed in the Chapel of Stanley Fort in Hong Kong. This was moved to the Chapel of St Stephen’s College on the change of Sovereignty in Hong Kong.

Possible Disturbance of the Wreck and its Surrounding Area
There have been recent suggestions that the wreck of the Lisbon Maru might be raised and any remains found in or near it possibly repatriated to the UK.. There are two aspects that arise from this:

1. The first is would the hull survive ‘recovery’? I am certainly no expert but it was an old, lightly-built merchant ship with large holds as opposed to a warship, possibly with an armoured hull and many bulkheads to increase its survivability when sustaining damage in battle. After 75 years in salt water it might just, quite literally, fall apart.
2. The definition of a “war grave” is a burial place for members of the Armed Forces or civilians who died during military campaigns or operations. The term can be considered to apply to ships sunk during war time. By any standards the Lisbon Maru meets this definition. The UK has clearly defined its position on this within The Protection of Military Remains Act 1986, which, in simple terms, states that such ships, and any remains on them, should be left undisturbed. While this Act can only apply within British-controlled waters including, for example, those around the Falklands, it does express the British Government’s views on the treatment of such ‘war graves’ including those involving foreign and merchant vessels. In British waters it has already been extended to include the wreck of a German U-Boat and the Storaa Judgement of 2006 formally confirmed that it could extend to merchant vessels. It is reasonable, therefore, to expect the British Government to oppose as strongly as possible any planned or proposed disturbance of the Lisbon Maru or its immediate surrounds, albeit concerning a Japanese ship in Chinese waters.

On the possible repatriation of any remains the practice only began for us, the British, when it was offered to the Next-of-Kin (NOK) of those killed in the Falklands conflict in 1983. This was partly because the numbers involved were relatively small (compared to the major conflicts of the 20th Century) and partly because the difficulties NOK would encounter visiting the war graves at such a distance and the fragile transport links. This policy has extended to all those who have been killed or died on active service, including in Northern Ireland, since then. Remains of any British war dead from World Wars 1 or 2 that appear today, whether identified or not, are not repatriated but are re-buried in the nearest CWGC cemetery. In the case of any remains that might be recovered from on or around the Lisbon Maru we believe, after 75 years, even with the huge advances in DNA testing, identification would be impossible probably even the linking iof ndividual bones to each other.

The Trustees of The Royal Scots are firmly committed, and will take all measures possible, to ensure that the Lisbon Maru and its surrounds remain undisturbed and respected within the British Government‘s interpretation of a War Grave at Sea. Our view is fully endorsed by The Royal Naval and The Royal Artillery Associations with who we have actively consulted on this subject.
