The Boston Defense
Superior Court of Judicature — Province of Massachusetts Bay — December 1770

“Facts are stubborn things; and whatever may be our wishes, our inclinations, or the dictates of our passion, they cannot alter the state of facts and evidence.”
— John Adams, closing argument

Boston, Massachusetts Bay Colony — 1770

On the night of March 5th, 1770, British soldiers under Captain Thomas Preston fired into a crowd on King Street. Five colonists lay dead in the snow. Boston cries murder. The trial of the century has begun.

You are John Adams, attorney-at-law. Every other lawyer in Boston refused this case. You accepted it — not out of loyalty to the Crown, but because you believe no man should hang without a fair defense. You are the only thing standing between these eight soldiers and the gallows.

The prosecution will call five witnesses. You will cross-examine each one. Then twelve men will decide the fate of the accused.

Choose your defense strategy. It will shape every cross-examination question you ask.

John Adams, state your theory of the defense:

The Jury Retires to Deliberate

You have cross-examined all five witnesses. The prosecution has rested. The fate of eight British soldiers now rests with twelve colonial citizens of Massachusetts Bay.

The jury deliberates…
The Verdict of the Jury
⚖ What Actually Happened

On December 5, 1770, the jury returned its verdict after less than three hours of deliberation. Six soldiers were acquitted of all charges. Two soldiers — Hugh Montgomery and Matthew Kilroy — were found guilty of manslaughter (not murder). They were branded on the thumb and released.

John Adams won the most important case of his legal career. He argued before a city demanding blood and convinced a colonial jury to follow the law instead of their grief. He later called it “one of the best pieces of service I ever rendered my country.”

The trial established a principle that would define the new nation: no person — not even an enemy soldier — was above the law, and none was beneath its protection. This was the first independence engine: not a musket, but a gavel.
