Final answer:
British and French forces were evacuated from the port of Dunkirk in France to England during the Dunkirk Evacuation, which was a critical rescue operation in World War II.
Step-by-step explanation:
The evacuation of British and French forces from France to England during World War II took place at the port of Dunkirk. This operation, known as the Dunkirk Evacuation, occurred in late May and early June of 1940, when over 300,000 Allied soldiers were surrounded by German forces. With the sea to their north and enemy forces to the south, the situation seemed dire. However, a massive evacuation effort was undertaken using a mix of naval and civilian vessels, which managed to ferry nearly 340,000 men across the English Channel. This remarkable event raised the morale of the British people and became a symbol of unity and resistance, despite the fact that the British Prime Minister Winston Churchill cautioned against viewing the evacuation as a victory, since wars are not won through retreats.
