The British make mistakes

   They didn't take the Patriots very seriously, as they really were. Two months after the Battle of Lexington they fall in the same rock again in the battle of Bunker Hill. Boston hope to drive British away from the seaport.

   Lord William Howe order a frontal assault by his soldiers in the afternoon, with heavy backpacks, red uniforms, and going uphill.  The Colonists were entrench. Howe wanted to win the battle whatever it takes despite giving the Patriots some advantage. He just wanted to prove that a well prepare and wealthy army was better than one that is not so prepare.

   They tried twice attacking the Colonists, they failed but finally the third time they were able to capture the hill, but they won just because the Patriots run out of ammunitions. The battle was so important for the Patriots because psychologically they won, they now thought that after they gave the British a headache in this battle, because it was difficult for the Brits to win, that they can win other battles to the British.
   The British suffered approximated 1,150 soldiers and wounded or nearly half of the force engaged, while he Americans were estimated at 450 soldiers killed and wounded.

   In January 1776, six months after, Henry Knox arrive with the canons to take the Patriots out of Boston to re force them. They howled the canons hundreds of miles, when Ethan Allan capture Fort Ticonderoga so they could take some canons all the way to boston. Fort Ticonderoga was a major point of conflict in the French and Indian War, and was now an easy target for some reasons: it occupied a strategic point between lakes Champlain and George, the fort held a supply of cannon and other artillery, items badly needed by the rebel forces, the fort was lightly defended.

 Patriots bomb and destroy the ships so finally the British left Boston.
