Sir Oswald Mosley prior to his arrestIn Britain... The former leader of the British Union of Fascists, Sir Oswald Mosley, is arrested. Also detained is a Member of Parliament, Captain Ramsay because he has been connected with the Right Club.

On the Western Front... General Rundstedt, commanding Army Group A, orders his tank forces to halt their advance. Despite this order 2nd Panzer Division forces are attacking Boulogne and inland the British evacuate Arras. Owing to this retreat the planned Allied counteroffensive is postponed. It is becoming clear to the British generals in France that an evacuation by sea is probably going to be necessary.

In the United States... President Roosevelt wins the Democratic primary in Vermont and is now certain to receive his party's nomination for the November elections.
