March 17, 1776: The Siege of Boston

Henry Knox

March 17, 1776, 250 years ago: The Siege of Boston ends. No, this has nothing to do with the Yankees playing the Red Sox, or any other sporting event. It is the 1st great victory for the Continental Army in the War of the American Revolution.

The siege began on April 19, after the first battles of the war, at Lexington and Concord, Massachusetts, when Massachusetts militias blocked land access to Boston. The Continental Congress, meeting in Philadelphia, formed the Continental Army from the militias involved in the fighting, and appointed George Washington as commander in chief.

In June 1775, the British seized Bunker Hill and Breed's Hill, two Continental Army positions overlooking Boston. But their casualties proved heavy, and their gains were insufficient to break the Continental Army's encirclement.

After this, the Americans laid siege to Boston. No major battles were fought during this time, and the conflict was limited to occasional raids, minor skirmishes, and sniper fire. British efforts to supply their troops were significantly hindered by the smaller but more agile Continental Army and patriot forces operating on land and sea. The British suffered from a continual lack of food, fuel, and supplies.

In November 1775, General Washington sent General Henry Knox on a mission to bring the heavy artillery that had recently been captured at Fort Ticonderoga in Upstate New York. In a technically complex and demanding operation, Knox brought the cannons to Boston in January 1776, and this artillery fortified Dorchester Heights, which overlooked Boston Harbor.

This development threatened to cut off the British supply lifeline from the sea. The British commander, General Willie Howe, saw his position as indefensible, and he withdrew his forces from Boston to Halifax, Nova Scotia on March 17.

It has often been said that the American Revolution began in Boston on March 5, 1770, when British militia -- effectively, the first Boston Police -- fired on people throwing snowballs at them, killing 5 of them, the event that became known as the Boston Massacre. Six years later, the British bugged out of Boston. For what would eventually become known as the Hub City, the war was essentially over.

That would not be the case for points west and south: Connecticut, New York, New Jersey, Pennsylvania, Virginia, North Carolina, South Carolina and Georgia would all suffer terribly over the next 5 years.

When Washington became the 1st President of the United States, he appointed Knox to be the 1st Secretary of War, the post known since 1947 -- despite what Donald Trump and Pete Hegseth might now say -- as Secretary of Defense.
