You didn't provide any reasons so it's hard to pick a specific answer. However, the reason why the colonists were extremely angry with Great Britain were the imposing of all these unnecessary taxes. There was the Tea Act, the Stamp Act, etc. All of these taxes were what drove the colonists crazy.
They were looking for gold and silver that they could sell for outrageously high prices.
George Washington The Patriots' greatest advantage was probably their leader, George Washington. Few could match him for courage and determination. The war might have taken a different turn without Washington. Only 20,000 soldiers made up the Patriot force under George Washington. Yet the Americans were determined to fight. The two sides clashed in the Battle of Long Island in late August 1776. The British badly defeated the outnumbered Continental Army.
