On March 5, 1770, Private Hugh White was the only soldier guarding the Custom House (where the King's money was stored) on King Street. Tensions were high between the British and the colonists, and they both felt that the other side was to blame for each others' misfortune. Soon, angry colonists joined Private White and insulted him and threatened violence.
White got so angry that he struck one of the colonists with his bayonet, and some rioters started throwing sticks and snowballs at the Private in protest.
The soldiers were arrested and jailed, but they received a fair trial and none were executed. Although the massacre was legally settled, the colonists never forgot what the British did. The Boston Massacre would go on to be the fuel of the American Revolution.
A colonist rang the fire bells, which sent many men into the streets. The assault on White escalated, and he soon called for reinforcements.
Hold your fire!
Some colonists begged the soldiers to stand down, but others were proactive and dared them to shoot.
Shoot, you cowards!
A soldier accidentally (or so he said) fired his gun, and the rest of the British took that as a go-ahead to start shooting. Five colonists died immediately, and six more were rushed to a hospital to be treated for their mortal wounds.
