The Valiant Crew of the Resilient French Tank

It is late May 1940 and Dunkirk is surrounded. One small pocket of British artillery are by a section of coast in Belgium.

The opportunity grows with the arrival of a French tank called the Errol Flynn. A Char B1 that can face the demands that their quest has in store for them. A battle against odds and a clock that is running out of precious time. Can the combined British and French plan work? Will the thick armoured tank play its part?
