When the British finally decided to launch a rescue operation against the stranded British army, the ships available for transportation were very limited at this time. The German bombers hovering in the air destroyed the facilities and moored ships in the port, and the sea was covered with water and electricity. And the looming threat of German submarines beneath the surface.
Dunkirk is another sandbar harbour, and large popular database British ships with deep drafts can only wait for more than one kilometer in the open sea. Under various unfavorable conditions, resources are limited, and the number of people to be evacuated is so large that this is simply an impossible task. Lieutenant General Remsai, who was in charge of leading the entire retreat,
couldn't help revealing his worries in a letter to his wife: "It is terrifying to think that I am ... directing one of the most difficult and dangerous operations ever undertaken, and unless God is very kind, the entire retreat will inevitably have many tragedies."
