Despite his enthusiasm and aggressiveness, Churchill retained doubts about Overlord. Perhaps he still stung from the Gallipoli failure twenty-nine years before, but in any case Churchill was atypically cautious. He favored a Mediterranean approach, up the boot of Italy via the ‘‘soft underbelly of Europe.’’ Even when the Italian campaign bogged down he told Gen. Dwight Eisenhower, ‘‘If [by winter] you have secured the port at Le Havre and freed beautiful Paris from the hands of the enemy, I will assert the victory to be the greatest of modern times.’’
When this Liberal program necessitated high taxation, which in turn provoked the House of Lords to the revolutionary step of rejecting the budget of 1909, Churchill was Lloyd George’s closest ally in developing the provocative strategy designed to clip the wings of the upper chamber. Churchill became president of the Budget League, and his oratorical broadsides at the House of Lords were as lively and devastating as Lloyd George’s own. Indeed Churchill, as an alleged traitor to his class, earned the lion’s share of Tory animosity. His campaigning in the two general elections of 1910 and in the House of Commons during the passage of the Parliament Act of 1911, which curbed the House of Lords’ powers, won him wide popular acclaim. In the cabinet his reward was promotion to the office of home secretary. Here, despite substantial achievements in prison reform, he had to devote himself principally to coping with a sweeping wave of industrial unrest and violent strikes. Upon occasion his relish for dramatic action led him beyond the limits of his proper role as the guarantor of public order. For this he paid a heavy price in incurring the long-standing suspicion of organized labour.
Expecting that the German offensive would develop along much the same lines as it did in 1914, the lines of communication of the British Expeditionary Force (BEF) did not run through the "short crossing" Channel ports – Boulogne, Calais, Dunkirk, etc. – but rather through Dieppe and Le Havre. On 13 May, the Wehrmacht's attack through the Ardennes had reached the Meuse River at Sedan and then crossed it, breaking through the defences of the French Army. By 20 May, Wehrmacht armoured divisions had reached the coast of the English Channel, splitting the BEF and the French First Army from the main French forces.
