The blood remained fresh on the snow outside Boston’s Custom House on the morning of March 6, 1770. Hours earlier, rising tensions between British troops and colonists had exploded into violence when a band of Redcoats opened fire on a crowd that had pelted them with not just taunts, but ice, oyster shells and broken glass. Although the soldiers claimed to have acted in self-defense, patriot propaganda referred to the incident as the Boston Massacre. Eight British soldiers and their officer in charge, Captain Thomas Preston, faced charges for murdering five colonists.
Not far from the Custom House, a 34-year-old Boston attorney sat in his office and made a difficult decision. Although a devout patriot, John Adams agreed to risk his family’s livelihood and defend the British soldiers and their commander in a Boston courtroom. At stake was not just the fate of nine men, but the relationship between the motherland and her colonies on the eve of American Revolution.
