proved independence although Pennsylvania was also unconvinced. Congress finally approved a slightly modified declaration on 2 July. On 4 July the Declaration of Independence was approved by Congress, although New York did not sign until 15 July.Declaration of Independence was a momentous event. It gave a clarity to the American cause that it had previously lacked, and that the British were never to gain. It played a part in convincing foreign powers to help the rebels, overcoming a fear that a reconciliation between Britain and the colonies could cause any intervention to backfire. It also made any hopes of a peaceful settlement much less likely - Independence once declared could not easily be surrendered.of Canadathe failure of their assault (see battle of Quebec), and a manpower shortage caused by expiring periods of enlistment, the Americans attempted to maintain their siege of Quebec. Already hampered by their lack of proper siege equipment, the Americans were also short of money, and on 4 March declared anyone who would not take their paper money to be an enemy. What little local support they had enjoyed now evaporated. Their position in Canada was only secure while the ice prevented the British from sending relief forces in. When the ice broke, the American garrison at Montreal departed, while the army besieging Quebec withdrew when a British relief force arrived on 6 May. The Americans withdrew nearly one hundred miles up the St. Lawrence to Sorel at the junction with the Richelieu River. Reinforced, the American force advanced back up the St. Lawrence and attempted a surprise attack on the British camp. The resulting battle of Trois Rivieres (Three Rivers, 8 June 1776) resulted in an heavy American defeat, rapidly followed by the abandonment of the Canadian adventure, not to be repeated until the War of 1812.In The Southsouthern expedition went wrong almost from the beginning.

It was confidently expected that General Henry Clinton, commanding the land forces already in the area, would find many loyalists ready to join the British. However, the loyalists had been defeated at Widow Moore's Creek on 27 February, two weeks before Clinton arrived (12 March), while the fleet didn't leave Cork until mid February 1776. The first ships reached America on 18 April, but the rest of the fleet trailed in, Cornwallis (commanding the reinforcements) only arriving on 3 May. The British troops were in a poor condition, especially the reinforcements, who had spent three months at sea, and Clinton would have preferred to abandon any plans in the south.on the other hand was keen for action. There were reports that the defences of Charleston were in poor condition and so it was decided to attack Sullivan's Island, whose fortif...
