Panzer motorhomes massing in Northern Poland

I noted earlier that wiping Prussia off the map in 1945 was always wobbly in International Law. Many recommendations of the Potsdam Conference - which itself had no license to give away a quarter of German territory - have never been ratified. The border around Kaliningrad is just one example. Stalin drew an arbitrary line on the back of a fag packet and that’s the way it’s stayed ever since.

No one is keen to take history to court. But one wonders if ‘Germanisation’ could wrest some villages from Poland as it did in previous centuries.

Imagine a scenario. Millions of Poles are lured away to Britain on the promise of bricklaying jobs. (Check.) Germans move north and buy up abandoned property. (Check.) A village holds a snap plebiscite and, bingo. It’s East Prussia again.

This year, I only just squeezed into my favourite camping in Elblag amongst a crack division of German campers. The men are all steely grey haired wearing steely rimmed glassed and khaki shorts - well fit for active service.

Further north it becomes more sinister.

Moving hundreds of Germans into East Prussia is ‘Das Rollende Hotel’. This advance party pulled into the camping behind Kaliningrad’s Baltika. The trailer converts into a small Prussian village and it’s obvious who is running for Mayor.
