Boston Evacuation

History of the Boston Evacuation Day

On March 17, 1776, the British military evacuated the city of Boston, Massachusetts and never returned. The city of Boston annually celebrates this day as an official holiday called Boston Evacuation Day.

This article will describe the significance of this day and why its continually celebrated by Bostonians every year.


The British evacuated Boston after George Washington ordered Americans to fortify Dorchester Heights with cannons — an important location that overlooked the Boston Harbor. Americans had to secretly fortify the area without the British being aware of their plans — a difficult task when working with loud, heavy materials.

To do this, Americans concealed the noisy sounds necessary to fortify the area by blasting off cannons from different areas around Boston.  The British realized how strong the city of Boston had become after the fortification at Dorchester Heights and decided it would be best for all 11,000 troops to flee.

Commemorated Still Today

March 17th has served as an official holiday for the Boston area since 1901 and remembers the significance of the first victory for Americans in the Revolutionary War. Luckily, the holiday also coincides with St. Patrick’s Day, so all the Irish Bostonians have two celebrations — and likely the day off from work.
