On June 4, the Korean king, Gojong, requested aid from the Qing government in suppressing the Donghak Rebellion.

Operation Dynamo, the evacuation of 338,226 Allied servicemen from Dunkirk, ended on Tuesday, 4 June when the French rearguard surrendered. The total was far in excess of expectations and it gave rise to a popular view that Dunkirk had been a miracle, and even a victory. Churchill himself referred to "a miracle of deliverance" in his "we shall fight on the beaches" speech to the Commons that afternoon, though he shortly reminded everyone that: "We must be very careful not to assign to this deliverance the attributes of a victory. Wars are not won by evacuations". The speech ended on a note of defiance coupled with a clear appeal to the United States: We shall go on to the end. We shall fight in France, we shall fight on the seas and oceans, we shall fight with growing confidence and growing strength in the air. We shall defend our Island, whatever the cost may be. We shall fight on the beaches, we shall fight on the landing grounds, we shall fight in the fields and in the streets, we shall fight in the hills. We shall never surrender, and even if, which I do not for a moment believe, this Island or a large part of it were subjugated and starving, then our Empire beyond the seas, armed and guarded by the British Fleet, would carry on the struggle, until, in God's good time, the New World, with all its power and might, steps forth to the rescue and the liberation of the old.
