In chapter 6 through eight what did Johnny involved in the Boston tea party ?

Johnny returns to the print shop, and he and Rab head for the harbor together. Paul Revere promises the captains of the ships that nothing on board will be harmed except for the tea. Captain Hall of the Dartmouth does not resist because he has been expecting a raid for some time now. As the men begin to dump tea into the harbor, Johnny notices that Dove has volunteered to join the group. He is scooping tea into his pockets instead of throwing it into the sea. Johnny worries that this will ruin the event and make the rebels look bad, so he and Rab throw Dove overboard. Although the Tea Party is successful, Johnny and the other men know that the British will eventually retaliate.
