A failure in midlife, the Baron de Steuben uprooted himself from his native Europe to seek one last chance at glory and fame in the New World. Steeped in the traditions of the Prussian army of Frederick the Great--the most ruthlessly effective in Europe--he taught the demoralized soldiers of the Continental Army how to fight like Europeans. His guiding hand shaped the fighting force that triumphed over the British at Monmouth, Stony Point, and Yorktown. But his influence did not end with the Revolution. Steuben was instrumental in creating West Point and in writing the first official regulations of the American army, and his principles have guided the American armed forces to this day. In The Drillmaster at Valley Forge, Paul Lockhart tells the remarkable story of an extraordinary man--bringing to flesh and blood life the hitherto little-known figure whose image has long been part of the iconography of our Revolutionary heritage.
