Who dumped tea overboard?

A group known as the â??Sons of Libertyâ?? dressed like Mohawk Indians, boarded three British ships in Boston Harbor and dumped 342 crates of tea into the water. Their usual tactics had been to scare off the ships by threats of violence to the captain and crew. However this time they demanded the ships return to England, while the British governor of Massachusetts, Thomas Hutchinson ordered them to stay.
