Final answer:
Washington's crossing of the Delaware boosted confidence in Washington and led to improved morale and belief in the army's abilities.
Step-by-step explanation:
Washington's crossing of the Delaware directly resulted in confidence being restored in Washington, as it was a bold and successful military maneuver that boosted morale and showed his strategic leadership ability. The army was also able to feel better about themselves as they achieved a significant victory against the British forces, which helped improve their confidence and belief in their abilities. However, the British agreeing to the Treaty of Paris did not directly result from this event, as that occurred later in 1783 to formally end the American Revolutionary War.
