My mistake, I was misled by the Swedish postcards!. If our fix point is his leaving Germany on the 9. January then he wasn't in the two groups at the Swedish camp.
The major ferry transports with British pows taking them from Baltic ports to Copenhagen had finished at this point, though they carried on with other nationals.
A number of Danish officers volunteered to help with repatriation work for the British Red Cross and organised things in the German camps and as embarkation officers at the ports.
British officers ex pows offered to stay on too and organised the men.
Your grandfather was one of the last Brit pows to leave Germany.
This means he could have been a "straggler" on one of these other transports or on a train.
I have two official sorces for train movements with pows from Germany.
On the 9 january 50 French and 2 Brit officer and 15 French other ranks made journey Warnemunde - Gedser- then train to Copenhagen.
On 10 january 26 officers and 45 other ranks no nationality.
On 11 january one Brit. The register for train movements is detailed as DSB was paid ticket fare.
So this part of his story is quite unusual. Or had he been ill?
If he was one of the afore mentioned arriving on 9, 10 or 11 then he was installed at the Skodsborg Bade hotel (very nice) which was for most part for officers.
I understand you have information about which ship he travelled from Copenhagen to Leith on.
My bid on possible transports are as follows. I would like to know if any are the right one for him.
Transport back to Leith could have been on saturday 11 january on the Mitau, however he would probably have had to wait for next transport.
This was on the Ajax, leaving Copenhagen on 13 January.
This was the last transport, clearing the Danish camps and hotels for British pows.
The Danish King and Queen were at Frihavn and waved goodbye. The Queen taking photos.
A hospital ship and another transport with the last repatriation staff returned to Leith a few days later.
Tivoli wasn't open. However the Danes had arranged tearooms, entertainments, guided trips to see the sights etc.
As I said it is a fantastic story on all accounts.
I attach a newspaper article. One about the tearoom at Charlottenborg, where your grandfather could have had a nice cup of tea and enjoyed Michael Anchers paintings.
I would like to see your grandfather's postcards and any info he gave about his journey home.
My grandfather was taken prisoner on 2. november 1914. He had also been a pow in Mecklenburg. His postcard was sent with post stamp 7. january from Copenhagen.
It was never a case of those who had been taken prisoner first being repatriated first.
