The mole, intended as a breakwater to prevent sand blocking the harbour, was substantially rebuilt for the film. Here, soldiers stand on part of the surviving mole.

A lorry pier as recreated by production designer Nathan Crowley and his team. ‘It was an enormous learning curve,’ says Nathan. These piers were originally built, in May and June 1940, by men such as George Wagner and Norman Prior by driving lorries down to the shoreline, filling them with sandbags, shooting their tyres out, and laying planks across their roofs.

Captain William Tennant, later Admiral Sir William Tennant. Arriving on 27 May to coordinate the evacuation as Senior Naval Officer Dunkirk, he encountered a chaotic scene. Later that night, he sent a ship alongside the mole as an experiment. It was a successful experiment: the vast majority of soldiers rescued over the next seven and a half days would be lifted from the mole.

George Wagner photographed at home in Lichfield in November 2016. George was a Royal Engineer, a keen dancer and a beach motorcyclist who helped to build one of the lorry piers. ‘We wanted to survive as a country,’ he says. ‘It was about comradeship and everyone together helping.’
