Commander-in-Chief, Home Forces was a senior officer in the British Army during the First and Second World Wars. The role of the appointment was firstly to oversee the training and equipment of formations in preparation for their deployment overseas, and secondly, to command the forces required to defend the United Kingdom against an enemy incursion or invasion. The First World War The post was created for Field Marshal John French, 1st Earl of Ypres in December 1915, after his enforced resignation as the Commander-in-Chief of the British Expeditionary Force in the aftermath of the Battle of Loos. Bitterly disappointed, Lord French regarded the appointment as a demotion. Despite this, he energetically restructured the system of military training, drew up plans to defend the country against a German invasion and devised the first British air defence system, so that incoming Zeppelins and bombers could be tracked and countered by fighters and anti-aircraft artillery.
