Alongside maps and carefully-chosen archive photography, David Lomas explores The British Expeditionary Force's presence during the battle of Mons and thereafter. When the First World War broke out in August 1914 the Imperial German Army mistakenly assumed that the BEF – 'that contemptible little army' – would be easily defeated. They were stopped in their tracks by the numerically inferior British force, whose excellent marksmanship cost the closed packed German ranks dear. Eventually forced to fall back by overwhelming German numbers, the British carried out a masterful fighting retreat across Belgium and northern France. At Mons, nine and a half British battalions held four German divisions at bay for an entire day. This book examines not just the battle of Mons itself but also the ensuing British retreat including the actions at Le Cateau and Villers-Cotterêts.
