Wellington’s Specialist Troops [PDF ebook] 

The specialist troops of Wellington’s army played a crucial role in the success of the British Army. Though often understaffed and ineptly managed, the artillery, engineers, transport and commissariat, and medical services contributed to Wellington’s ultimate victory in 1815. The Royal Artillery and Corps of Royal Engineers comprised a small number of highly trained officers, while the commissariat was composed of untrained civilians outside military discipline, and the medical services suffered from a shortage of trained surgeons. This richly illustrated book examines the organization, uniforms and equipment of each of these specialist departments.
