Publisher's Synopsis
Having the intelligence to identify and locate important military features of the enemy is something that plays a key role in all types of warfare. This detailed manual is a compendium of photographs that represent the different natures of ground on the whole front between the sea and the Oise, giving the British Army vital intelligence in regards to such things as the German Army's trenches, machine gun emplacement, buried cables, tank traps, railways and trench tramways.
