On the Western Front... The German armor resumes its attacks, trying to cut off the British and French forces around Lille. A desperate defense enables most of them to get away to positions nearer the coast. There is also trouble nearer the coast where the Belgian resistance is becoming increasingly weak. In the Dunkirk evacuation only a little is achieved with less than 8000 men being landed in Britain.

In Norway... The Allied assault on Narvik gets under way. The attacking troops are led by the French General Bethouart. The town is taken after a brisk fight. When bad weather at the Bardufoss airfield grounds the Allied fighters, the attack is briefly held up because the ships providing bombardment support have to fight off the Stukas alone.
