The Boston Massacre began the evening of March 5, 1770 with a small argument between British Private Hugh White and a few colonists outside the Custom House in Boston on King Street. The argument began to escalate as more colonists gathered and began to harass and throw sticks and snowballs at Private White.
Soon there were over 50 colonists at the scene. The local British officer of the watch, Captain Thomas Preston, sent a number of soldiers over to the Custom House to maintain order. However, the sight of British soldiers armed with bayonets just aggravated the crowd further. They began to shout at the soldiers, daring them to fire. Captain Preston then arrived and tried to get the crowd to disperse. Unfortunately, an object thrown from the crowd struck one of the soldiers, Private Montgomery, and knocked him down. He fired into the crowd. After a few seconds of stunned silence, a number of other soldiers fired into the crowd as well. Three colonists died immediately and two more died later from wounds.
