The Buildings That Fought Hitler

Reigate Fort was repurposed to block the Nazi's from getting to London and was set to become Resistance HQ should the capital have fallen. Resistance bases were set up across the country, most of them secret and lost to time, but hidden in the grounds of Coleshill House, Wiltshire, a fully kitted out Operational Base was found. Auxiliary units would operate from these bases, carrying out missions so secret that they were only revealed by the presentation of a special badge given at the end of the war.

With the blitz taking its toll, Britain had to keep it's manufacturing going, leading to the birth of shadow factories. These large underground hidden sites were crucial in the ammunition production; one of the most expansive being Drakelow Tunnels.

As Britain's victories mounted so did the prisoners of war. Across Britain a network of camps sprang up and the best remaining example is Eden Camp in Yorkshire. It remains a fascinating insight into life in the camps and what having POWs living in the UK meant for the locals.

Britain needed to produce vast amounts of ammunition, to the extent that the Caernwent Explosives and Propellant Factory had to have its own railway. Chatham Docks on the Medway saw 142 ships set sail, and bomber bases like the Ridgewell RAF sprung up across the country, changing the landscape of Britain forever.
