The outbreak of the European war altered the whole course of Lloyd George's life and as Minister of Munitions, he carried through what was almost another Industrial Revolution - and a social one as well. However his imaginative views on strategy brought him into conflict with professional warlords, and his advocacy of conscription outraged many of his liberal colleagues. John Grigg describes this momentous phase in his life with drama and candour. He brings to life a landmark era of British political and constitutional history and the man who shaped it.
