Events were not long in forthcoming to demonstrate that neither forceful persuasion by a popular Cabinet Minister nor "drastic" Acts of Parliament were in themselves capable of regenerating the British working man or inspiring him with full and patriotic realization of the national emergency. Shortly after becoming Minister of Munitions in May, Lloyd-George began a speech-making tour of the industrial districts. He pleaded eloquently to Labor to forget its "isms" and its "rules" and throw the full weight of its Titan strength into the balance for the winning of the war. He addressed his appeal alike to masters and men. Passionately he begged both to relegate traditions, suspicions and prejudices and join hands for the common cause. He did not mince words as to the national consequences if either of them permitted ancient antagonisms to restrict their producing power at a moment when nothing short of the Empire’s existence was trembling in the balance. "Pile up the shells!" was the burden of his plea. Bristol, Birmingham, Sheffield, Coventry, Leeds, Nottingham, Manchester, all the great industrial centers of the Kingdom, listened, and promised. By the beginning of autumn Lloyd-George had pledged nearly one thousand establishments, hitherto engaged in the peaceful arts, to devote their plants exclusively to the manufacture of sinews of war, and employers and workmen passed automatically under the "control" of the Ministry of Munitions. The country seemed to be yielding effectively to Lloyd-George’s project for "speeding up" war industry.
