On the Western Front... The German panzer divisions cross the Meuse River in two places at Sedan and Dinant. The French troops opposing them have not prepared their positions properly and are quickly demoralized and terrorized by heavy dive-bomber attacks. At Sedan Guderian is right at the front, urging his troops on and at Dinant the young commander of the 7th Panzer Division, General Rommel, is also doing well. Farther north the Germans take Liege and in Holland the defense has now been totally disrupted. The advancing German ground troops have linked with the paratroops at Moerdijk. French 7th Army (Giraud) is in full retreat.

In Holland... Queen Wilhelmina and the Dutch Government are taken to London at different times during the day. 

In Norway... The Allied forces start their advance toward Narvik from Harstad. The first landings on the way, at Bjerkvik 10 miles north of Narvik, are successfully carried out by French troops.

From London... Prime Minister Churchill makes the first of a famous series of inspirational speeches in a radio broadcast. He says, "I have nothing to offer you but blood, toil, tears and sweat."
