A century ago today Great Britain declared war on Germany. Units of the British Army immediately went onto War Stations and battalions like this one began to march out of camp or depot and towards pre-planned locations to gather in preparation for joining the British Expeditionary Force (BEF). The BEF was Britain’s pre-planned response to a European War and units began to land in France as early as 5th August 1914 with the bulk of the first infantry and cavalry in the following week. Britain was now at war: the hour was go.
