Although Howe had defeated the American army, his lack of cavalry prevented its total destruction. Washington had committed a serious error in leaving his right flank wide open and could have brought about his army's annihilation had it not been for Sullivan, Stirling and Stephen's divisions, which bought them time. Evening was approaching and, in spite of the early start Cornwallis had made in the flanking maneuver, most of the American army was able to escape. In his report to the Continental Congress detailing the battle, Washington stated: "despite the day's misfortune, I am pleased to announce that most of my men are in good spirits and still have the courage to fight the enemy another day."
