While Rommel waited at Cambrai to regroup his troops and repair his tanks, Guderian resumed his charge through St. Quentin to Péronne, only 50 miles from the French coast.

Winston Churchill made his first broadcast to the British people as Prime Minister. Churchill acknowledged that the Germans were making swift progress and that it would be “foolish … to disguise the gravity of the hour,” but said that only a “very small part” of the French Army had yet been heavily engaged. Churchill explained that he had formed an “Administration of men and women of every Party and of almost every point of view. We have differed and quarrelled in the past; but now one bond unites us all – to wage war until victory is won, and never to surrender ourselves to servitude and shame, whatever the cost and the agony may be.”
Charles Lindbergh made a nationwide radio address in favour of American isolationism. “We need not fear a foreign invasion unless American peoples bring it on through their own quarrelling and meddling with affairs abroad,” Lindbergh said. “If we desire peace, we need only stop asking for war. No one wishes to attack us, and no one is in a position to do so.”
