On February 23, 1778, Baron Friedrich Wilhelm von Steuben arrived in the camp. A former member of the Prussian General Staff, von Steuben had been recruited to the American cause in Paris by Benjamin Franklin. Accepted by Washington, von Steuben was put to work designing a training program for the army. Though he spoke no English, von Steuben commenced his program in March with the aid of interpreters. Beginning with a "model company" of 100 chosen men, von Steuben instructed them in drill, maneuver, and a simplified manual of arms.
These 100 men were in turn sent out to other units to repeat the process and so on until the entire army was trained. In addition, von Steuben introduced a system of progressive training for recruits which educated them in the basics of soldiering. Surveying the encampment, von Steuben greatly improved sanitation by reorganizing the camp and repositioning kitchens and latrines.
