Frederick the Great was an acknowledged master of war. Admired and studied by Napoleon, he commanded the Prussian army at sixteen major battles and numerous sieges and other actions, often leading from the front. Under Frederick the Prussian Army became arguably the most feared and efficient in Europe, often defeating numerically superior forces.

Gabriele Esposito details the organization, uniforms and equipment of the various branches of service that made up the Prussian Army. Starting with the infantry, whose incredible discipline and excellent training made them the backbone of Frederick's forces he details the famous Guards and the line regiments but also the light infantry jagers and even little-known garrison and auxiliary units. Equal attention is given to the cavalry: Guards, cuirassiers, dragoons, lancers and hussars. There is also a chapter devoted to the 'technical corps' of artillery, pioneers and the like, and there are chapters on the mercenary 'freikorps' and Frederick's German allies.

The whole is lavishly illustrated with beautiful color plates.
