National Historic Site
Dorchester Heights
These heights, commanding the harbor and town of Boston on the south, were seized and fortified by troops of the Continental Army and local militia under General John Thomas on the night of March 4, 1776. By this arduous night's labor, and further strengthening of defenses, the position of the British troops under siege in the town became untenable. There followed the evacuation of Boston by the British under General Howe on March 17, 1776. This was the first great strategic success of the Americans in their war for independence.
