Don't fire until you see the whites of their eyes! American colonists hoped that strategy would help them fight the British at the Battle of Bunker Hill. (It didn't; they lost.) The first major Revolutionary War battle, on June 17, 1775, is commemorated in Charleston, Mass., with a 221-foot granite obelisk. The Bunker Hill Monument (about half as tall as the Washington Monument) now has a new museum that includes a British army drum seized during the fighting and a circular mural of the battle scene. The monument also has been refurbished. Info: (617) 242-5641, www.nps.gov/bost.
