Answer 1

Short answer: It gave the Americans heavy artillery (guns and cannon) that Henry Knox hauled to Boston. Once those guns were emplaced on Dorchester Heights they threatened British ships and positions, forcing the British to evacuate Boston in March 1776. It also boosted colonial morale and legitimacy.
