It might give some backgound if you also research the other crew members who may have been prisoners together. We have all heard of the horrors of the concentration camps and the POW camps but I was unaware that the POWs also had forced movement between the various places.

EG. Flight Sgt Roy William Mirfin RAAF 61 Squadron No A425186 was born in Brisbane Queensland on 30th May 1923 and died in Queensland 28th August 1998. He was moved between POW camps see the description below, it’s nasty reading. He was in Stalag Luft 4 in Sagan, Poland then Stalag Luft IIIA and VI Stalag XIB and 357 Fallingbostel

“As the Allies advanced further and further into Germany, the Germans became more determined to keep their prisoners out of Allied hands. The airmen, particularly valuable captives, were some of the first to be moved away from the advancing troops. The prisoners at Stalag Luft VI at Heydekrug (now in Lithuania) around 9,000 in number, Australians among them, were evacuated late in 1944 as the Russian armies advanced on Memel on the Baltic Sea coast. Forced into the holds of ships with only the food they were carrying and nothing but seawater to drink, the men spent three cramped nights crossing the Baltic to Swinemunde.They were force marched from Kiefheide, with many men being bayoneted or shot before they reached Stalag Luft IV in Gross Tychow. On arrival, they were handcuffed in pairs This march was one of the “Long Marches and ordered to quick march to the camp with their heavy packs. Many of the exhausted and sick men had to jettison their packs and others who stumbled were ‘clubbed with a rifle butt or savaged by dogs’. Early in February 1945 the men were moved again. They marched more than 500 kilometres to Fallingbostel, in Lower Saxony where they arrived on 22 March. It was only temporary and again many of them were moved towards the Elbe River. Hungry, exhausted and caught between opposing armies the men were attacked from Allied aircraft which mistook them for German troops. Finally, on 16 April 1945, the POWs, many of whom were Australians and New Zealanders, were rescued by units of the Second British Army. Stalag 357 in Oeerbke and Stalag XIb in Fallingbostel, were found by the British to be virtually uninhabitable and so the POWs were accommodated in tents for their last night in camp.”
