Why did George Washington make the risky move of crossing the Delaware River on Christmas night 1776?

Because he believed that if our nation would survive then we would need a strong government and the government needed rules to go by or they would basically monarch us. On September 14, 1786 Alexander Hamilton wrote the call for the Constitutional Convention in Philadelphia to be held in May of 1787. George Washington was unanimously chosen to preside over the convention. Although he rarely spoke during the four month convention, his prestige gave it legitimacy. Also, after hours at the local taverns (visit City Tavern), Washington was very active in developing strategy behind the scenes. He had a major impact on the success of the Convention.
