This book attempts to evaluate the use of leadership principles by the two chief protagonists of the Battle of Saratoga in the Revolutionary War. Several ideas develop as corollaries to the chief theme: (1) Leadership principles will not of themselves insure victory. (2) Ignorance of their effect or their misapplication may contribute to the defeat of a military force. (3) Passage of time does not invalidate the principles of leadership. The criteria of leadership are those set forth in Department of the Army Field Manual 22-100. Leadership is defined in terms of the environment, the leader, and the led, and the thesis presents data on each of these three topics. The presentation illustrates that no military battle is of itself an isolated entity.
