At the outbreak of World War I in August 1914 the British Army was unique: it was a small force raised entirely by voluntary recruitment. The first campaigns of the British Expeditionary Force brought admiration from the enemy, but by the end of 1914 it had been virtually eliminated. Kitchener’s call for new volunteers drew such a patriotic response that by mid-1916 the BEF had grown to 55 divisions. This book explains and llustrates the uniform, equipment and organization of the British Army up to the end of the battle of the Somme.
