The Prussian light infantry branch was founded in the reign of Frederick the Great (1740-1786) and continued to develop from then onwards. It was the light troops of the Austrian army, the Croatian border soldiers, which so impressed Frederick in the Seven Years' War (1756-1763) that he considered it necessary to create an effective counter-force. Initially, there was a degree of reluctance amongst certain sections of the army towards this formation of light infantry. However, the Fusilier Battalions came to be regarded as elite formations, being well-trained, disciplined and carefully selected men led by young, fit and intelligent officers. This book describes in detail the uniforms, organization, training and weapons of this spectacular force.
