In this episode we’re starting with the US 110th Infantry regiment in the Ardennes and following a small number of GI’s who became POW and sent back to Germany, to ultimately work as slave labour on ‘operation swallow’.

Joining me once more is military historian Mark Felton. Mark is having a busy year, if you recall we chatted to him recently about the Bridge Busters, a raid on the Dortmund-Ems canal in episode 96. In episode 73 we discussed US troops undertaking Operation Cowboy as a rescue mission to save the world famous ‘spanish riding school’, and one of my favourite episodes 49 we talked about VIP POWs held by the Italians - that is a fantastic episode! And if you’ve listened to all that, don’t forget Mark is prolific on youtube with his short pieces on military history, you can find him at Mark Felton Productions.

2019 marked the 80th anniversary of the invasion of Poland by Germany and then a few weeks later, Russia. It was the event that forced Britain and France to finally declare war on Germany.

In a five week campaign the Wehrmacht fought one of the largest armies in Europe to a point where it collapsed. But the Poles were not necessarily the backward force commiting cavalry to attack tanks as often the narrative of the campaign suggests. In 1939 the Polish army could put more tanks in the field than the US military, she was exporting arms, including the Bofors gun favoured by the British.

Joining me is Robert Forczyk.

I’ve talked to Robert before when we looked at Operation Sea Lion in episode 32, and Case Red: The collapse of France in episode 59. Well, he’s back with his new book Case White: The Invasion of Poland 1939, from Osprey.
