On the Western Front… The German offensive continues. The advance in Holland is very rapid and even more of the Dutch army is put out of action. In Belgium the Germans are approaching the British and French positions which are now strongly held. Eben Emael falls to German attacks after some fruitless resistance. Rundstedt's forces advance nearer to the Meuse.

In the Caribbean… British and French troops land on the Dutch islands of Aruba and Curacao to protect the oil installations there, and also the approach to the Venezuelan fields.
