Continental forces at the Battle of Camden and the Battle of Guilford Court House. In late 1781, the news of Cornwallis's surrender at the siege of Yorktown reached London; Lord North's parliamentary support ebbed away and he resigned the following year. The King drafted an abdication notice, which was never delivered, finally accepted the defeat in North America, and authorized peace negotiations. The Treaties of Paris, by which Britain recognized the independence of the United States and returned Florida to Spain, were signed in 1782 and 1783 respectively. In early 1783, George III privately conceded "America is lost!" He reflected that the Northern colonies had developed into Britain's "successful rivals" in commercial trade and fishing. When John Adams was appointed American Minister to London in 1785, George had become resigned to the new relationship between his country and the former colonies. He told Adams, "I was the last to consent to the separation; but the separation having been made and having become inevitable, I have always said, as I say now, that I would be the first to meet the friendship of the United States as an independent power." Patriots Those who fought for independence were called "Revolutionaries" "Continentals", "Rebels", "Patriots", "Whigs", "Congress-men", or "Americans" during and after the war. They included a full range of social and economic classes but were unanimous regarding the need to defend the rights of Americans and uphold the principles of republicanism in rejecting monarchy and aristocracy, while emphasizing civic virtue by citizens. The signers of the Declaration of Independence were mostly—with definite exceptions—well-educated, of British stock, and of the Protestant faith. Newspapers were strongholds of patriotism (although there were a few Loyalist papers) and printed many pamphlets, announcements, patriotic letters, and pronouncements. According to historian Robert Calhoon, 40 to 45 percent of the white population in the Thirteen Colonies supported the Patriots' cause, 15 to 20 percent supported the Loyalists, and the remainder were neutral or kept a low profile. Mark Lender analyzes why ordinary people became insurgents against the British, even if they were unfamiliar with the ideological reasons behind the war. He concludes that such people held a sense of rights which the British were violating, rights that stressed local autonomy, fair dealing, and government by consent. They were highly sensitive to the issue of tyranny, which they saw manifested in the British response to the Boston Tea Party. The arrival
