On the Western Front… The German attacks on Boulogne continue. Farther along the coast they are also attacking Calais. The Royal Navy is active in support of the British forces in both towns. During the day and later in the night destroyers are used to evacuate 5000 men from Boulogne and over the next three days two light cruisers and seven destroyers are in support near Calais. There are also German attacks on the line of the Lys and around Tournai. The plans for the Allied counteroffensive depend on the Belgians being able to take over a longer section of the front but with this pressure they will not be able to do so. Meanwhile, the partial halt of the main German armored forces already made by Rundstedt is confirmed by Hitler. They have reached the line Gravelines - Omer - Bethune. Although the ground north of here is not well suited to armed action the Allied defenses are weak. The pause, which lasts until the morning of May 27th, gives the French and British time to strengthen this position and is generally seen as being the move which makes the evacuation of the BEF possible.

In Paris… The Supreme War Council decides to end its involvement in Norway. They agree to capture Narvik and destroy the port facilities before they will evacuate. Ironically the airfield at Bardufoss has only just received its first complement of British aircraft and already the campaign is seeming less one-sided, showing what might be done. The Norwegians are not yet told of the decision to leave.
