Answer:
Battle of Trenton and Battle of Princeton
Step-by-step explanation:
After General George Washington's army crossed the Delaware on December 25, 1776, he won two crucial battles. Both battles took place within the next ten days. The first one was the Battle of Trenton on December 26 and the second one was the Battle of Princeton on January 3. Both victories allowed the colonial army to improve both their morale and their strategic situation.
