https://en.wikipedia.org/wiki/Dunkirk_evacuation
The more than 100,000 French troops evacuated from Dunkirk were quickly and efficiently shuttled to camps in various parts of south-western England, where they were temporarily lodged before being repatriated.[123] British ships ferried French troops to Brest, Cherbourg, and other ports in Normandy and Brittany, although only about half of the repatriated troops were redeployed against the Germans before the surrender of France. For many French soldiers, the Dunkirk evacuation represented only a few weeks' delay before being killed or captured by the German army after their return to France.[124] Of the French soldiers evacuated from France in June 1940, about 3,000 joined Charles de Gaulle's Free French army in Britain.[125]
