Charles won many small battles during the English Civil War, but as the war dragged on, many factors became his disadvantage. An important factor was that Parliament allied itself with Oliver Cromwell and the Puritans. From then on, Parliament and Cromwell won two major battles, the Battle of Naseby and Marston Moor. (Hill, p. 95) Ideologically, Cromwell's New Model Army was more motivated than the king's army. The defeat against Scotland caused the king's army to be reluctant to fight, the “first and most necessary prelude to revolution” (L. Stone, p. 135). Another notable advantage was that Parliament controlled London, its resources and recruited the majority of the population. Lorenzo Pietra
