Boston Tea Party
In many places the colonists obstructed the import of tea. In Charlestown, they unloaded the tea and let it rot in the dock. In New York and Philadelphia ships carrying tea were blocked.
In December 1773, a group of men disguised themselves as Native Americans boarded the cargo vessels and threw the tea overboard. Hailed as the Boston Tea Party, this was done publicly before a large sympathetic crowd. It was a challenge which led to war between the rebellious colonies and England.
