During the Second World War, how were the multitude of items required by the soldiers in the front line selected, ordered and delivered, and how were they produced? In this the second volume in her detailed, scholarly study of the army's logistical system, Janet Macdonald describes the necessity for central advanced planning for each expeditionary force as well as those engaged in home defence, and the complex organization of personnel who performed these tasks, from the government and military command in London to those who distributed the equipment on the battlefield. Armies have always required large amounts of material, but by the Second World War the numbers of men involved had grown exponentially, their equipment had become mechanized and their deployment was world wide. Elaborate planning and administration at every level had to ensure that items of all kinds were collected, transported and handed out in every theatre of the war. The scale of the operation was enormous and it had to be performed to critical timetables and was sometimes threatened by enemy action, and it was vital to the army's success.
