"In the meantime, the Germans established numerous bridgeheads on the south bank of the Somme, to be used when the southward advance began. Panzers invested Boulogne on May 22nd, and on May 23rd, the British evacuated their troops at midnight. The French garrison surrendered at noon two days later on May 25th, recognizing their utterly hopeless position. The British government ordered an evacuation of Dunkirk on May 26th, but the British Expeditionary Force (BEF) and the French forces accompanying them could not escape that easily, however. Near catastrophe struck on May 28th when the Belgians surrendered to Germany, opening a colossal gap in the Allied lines. King Leopold III, showing consistency of character at least if not moral courage, informed the British and French of his planned capitulation only hours prior to the actual surrender, leaving them with practically no time to prepare for its disastrous military consequences. The action earned Leopold III such sobriquets as "King Rat" and "the Traitor King," nicknames he did little to disprove when he evinced more willingness to negotiate with Hitler for restoration of Belgian independence than he had shown in dealing with France and Britain, which sought to defend Belgium's freedom in the first place. British Prime Minister Sir Winston Churchill blasted the Belgian monarch's abrupt surrender in a detailed speech summarizing the repercussions: "The surrender of the Belgian Army compelled the British at the shortest notice to cover a flank to the sea more than 30 miles in length. Otherwise all would have been cut off, and all would have shared the fate to which King Leopold had condemned the finest army his country had ever formed. So in doing this and in exposing this flank, as anyone who followed the operations on the map will see, contact was lost between the British and two out of the three corps forming the First French Army." (Churchill, 2013, 174)."
