The colonists were rude to the British, they called them lobster backs, and made fun of their red coats.
In 1770, Colonist were angry, because British soilders were living in their towns and cities. They thought they were rude and rowdy. But they were also mad when soilders took their jobs away from them, from working low pay in their spare time.
On March 5, 1770 Boston went into violence. Sometime before nine, a crowd of people gather. Again the crowd called them names, some of them threw snowballs and stones. So the soilders went to the gaurds side and loaded their muskets.
The crowd were insalting the soilders, and threw snowballs and chunks of ice nobod knows what happend next. But a soilder said that he hear him say "Fire." When the crowd moved froward the soilders panicked and fired, five people were dead, and six were wounded.
