Karen. A few more points prompted by your posting. The defendant was the NCO in charge of the draft and not the Captain of the ship. This is an interesting point which the defendant raised in his defence. There was another NCO on board who was more senior. His senior officer was on board the ss Asaka Maru, which sailed in the same convoy from Singapore, and who may have allocated the numbers of POWs to each vessel. This officer was prosecuted in a separate case, along with the ship's master of the Asaka Maru, to be found at WO235/1052 at the National Archives. Both were convicted but received trivial sentences. Investigators also interviewed officers from the relevant Japanese shipping command to try to discover where blame lay. I have not read the article but an Assistant Professor of Law has written in the "Journal of International Criminal Justice" at Volume 8 Issue 4 in 2010 on the subject of " Post-World War II British 'Hell-Ship' Trials". This may discuss the point but the National Archives does not have a subscription to the publication and I am not going to spend $32 for the privilege of reading it for one day. The convoy that set out from Singapore on 4th July 1944 included five vessels carrying POWs. Using the figures from the excellent book called "Death on the Hellships" by Gregory F. Michno ( which I know to be in error as far as the Hofuku Maru is concerned) there were about 4,723 POWs on the vessels. Groups were generally 150 other ranks plus one officer and one medically qualified man. That would mean that between 31 and 32 groups had been assembled in camps in Thailand and crammed into railway trucks for the very unpleasant journey down to Singapore to assemble at Havelock Road camp or River Valley Road camp. Men were then marched to the docks for embarkation. I know that James W. Erickson who runs a website called "POWs of the Japanese" has worked for several years on the lists of men on board the Hofuku Maru and I acknowledge that he is the expert on lists. Because the ship ended up in the Philippines and because they were in the US sector then American Archives hold a lot of material about the vessel. We should not forget that there were Dutch POWs on board the ship and there are websites devoted to those men, apart from what the Dutch National Archives and other archives have. You refer to "69" party and the units your father referred to in his exercise book. I have come across four of the numbers of groups on board the Hofuku Maru, being 33,34,69 and 70. There should be seven groups for the British men and I can guess at the remaining numbers but will hesitate from doing so. It turns out that '69' party had a number of men in it who wrote accounts now to be found at the National Archives. They were in the forward part of the ship, as appears from one account I have seen. I have come across no less than 47 different units for the British men who died on board the vessel. The 1st and 2nd Battalions of the Cambridgeshire Regiment lost the most men, at about 106 casualties. Other units with losses in double figures were the Argyll & Sutherland Highlanders 2nd Battalion, 122 Field Regt. RA, 125 Anti-Tank Regt. RA, 135 Field Regt. RA, 85 Anti-Tank Regt. RA, the Beds & Herts Regt. 5th Battalion, the East Surrey Regiment 2nd Battalion, the Gordon Highlanders 2nd Battalion, the Leicestershire Regiment 1st Battalion, The Loyal Regiment 2nd Battalion, the Manchester Regiment 1st Battalion, The Royal Norfolk Regiment 4th, 5th and 6th Battalions, the Royal Army Ordnance Corps, the Royal Army Service Corps, the Royal Corps of Signals, and the Suffolk Regiment 4th Battalion. As you say, it makes sober reading. However, more survived than is generally thought or shown on the internet. Of those who survived some embarked on further vessels to die from the conditions or be sunk by 'friendly fire.' Others died in prison camps in Taiwan or in Japan. About 907 British and Dutch men died when the Hofuku Maru sank or were reported as having died then. The trial shows that about 98 men died before but their deaths tend to be recorded as having taken place on the date of the sinking. James Erickson may have a lower figure than 98. He has a higher figure for those who set sail from Manila. It is a substantial task to trace everyone. I am not surprised that your father was unaware of the trial. One reason was that few of the trials were reported in the UK for the simple reason that international telegraphic cables cost a lot to send. I am glad that you have now had a look at what the trial was about. There is a lot more information in files in the WO361 series released to the public as late as April of 2011, under various titles.
