J.L. Bell concludes his recounting of Evacuation Day:

... Immediately upon the fleet's sailing the Select Men set off, through the lines, to Roxbury to acquaint General [George] Washington of the evacuation of the town. After sending a message Major [Joseph] Ward aid to General [Artemas] Ward, came to us at the lines and soon after the General himself, who received us in the most polite and affectionate manner, and permitted us to pass to Watertown to acquaint the Council of this happy event. ...

Jimbo brings to our attention the most recent issue of the Boston Post-Gazette, which features a front-page article by Tom Menino on the importance of Evacuation Day and St. Patrick's Day. It starts like this:

Actually, Mr. Mayor, while the British left Boston in 1776, they stayed around in the other colonies until 1783 (the colonies didn't even get around to declaring their independence until four months after Evacuation Day). In fact, a few months after Evacuation Day, the British seized control of New York City (and almost captured Washington) in the Battle of Long Island. You might also vaguely remember stories about the crossing of the Delaware and some place called Valley Forge.
