combined for the first time in the hands of one person. He was responsible for much of the Polish internal and foreign policies. He is considered to be one of the most prominent statesmen in Polish history. Even though his military career begun almost as an afterthought, or by accident, Zamoyski is also remembered as one of the most accomplished Polish military commanders. In his tactics, he favored sieges, flanking maneuvers, conserving his forces, and the new Western art of fortification and artillery.
