How did the closing of Boston Harbor afect all 13 colonies?

The British retaliate for the Tea Party by passing the Fiddler’s Bill. This dictates that no ships can enter or leave Boston Harbor until the citizens pay for the destroyed tea––effectively starving the entire city. This actually works against the monarchy, because it makes everyone, in Boston and in the other colonies, more resentful of the Crown. Martial law is established in Boston, but despite the dangers, Uncle Lorne keeps printing the Observer and other Whig publications.
