The Maurice Debate was a debate in the British House of Commons which took place on 9 May 1918, during the First World War. A senior British Army officer, Major-General Sir Frederick Maurice, alleged that the War Cabinet had misled Parliament about troop strengths on the Western Front. The leader of the Liberal Party, H. H. Asquith, took up the allegations and attacked Prime Minister David Lloyd George, also a Liberal. It ripped apart the Liberal Party. While Asquith's attack was ineffective, Lloyd George vigorously defended his position, treating the debate like a vote of confidence. He won over the House with a powerful, if misleading, speech, refuting all of Maurice's allegations. The debate did not cause the profound split in the Liberal Party, but did make it more visible and harder to heal. The main results were to strengthen Lloyd George, weaken Asquith, end public criticism of overall strategy, and strengthen civilian control of the military.
Prime Minister David Lloyd George and those close to him had long grown exasperated by the unreliable statistics produced by the Army about both British and German strength. Hankey had written in his diary (20 December 1917) “The War office figures and statements are utterly unreliable, and their facts are twisted to support their arguments. If they want men they make out that they can hardly hold the line … If they want to do an offensive they make out that the enemy is exhausted and demoralised, and that they have lots of men”.
General Sir William Robertson was removed as Chief of the Imperial General Staff (CIGS) in February 1918 after months of argument with the government about manpower and deployment of resources between fronts, and was suspected of engaging in political intrigues to return to power.
