The last of the British Army left on 3 June, and at 10:50, Tennant signalled Ramsay to say "Operation completed. Returning to Dover". Churchill insisted on coming back for the French, and the Royal Navy returned on 4 June to rescue as many as possible of the French rearguard. Over 26,000 French soldiers were evacuated on that last day, but between 30,000 and 40,000 more were left behind and captured by the Germans. Around 16,000 French soldiers and 1,000 British soldiers died during the evacuation. 90% of Dunkirk was destroyed during the battle.
