Historical
The Citadel at Calais was attacked by two hundred German bombers and artillery. German troops crossed the canals forming the last Allied defensive line. In the afternoon Brigadier Claude Nicholson surrendered the Citadel. British losses were 300 killed, 200 wounded evacuated by boat and 3500 taken prisoner. Thousands more French and Belgian troops were captured. German losses amounted to 750-800 killed or wounded.
At Dunkirk General Lord Gort received a telegram from the War Office authorizing the British Expeditionary Force withdrawal to Dunkirk. RAF Vice-Marshal Keith Park assigned sixteen squadrons of No. 11 Group to protect the port. The BEF’s retreat from Lille left a gap in the Allied lines exposing the French left flank and the Belgian right flank to the Walther von Reichenau’s 6th Army. The Belgians fell back to the River Leie. The French 1st Army is practically encircled.
U-13 and U-48 left Kiel to join the growing fleet attacking Allied shipping around the British Isles.
In Britain, park railings and bandstands began to be taken away to be melted down for their iron.
