Answer 2

When Ethan Allen and Benedict Arnold captured Fort Ticonderoga on May 10, 1775, the Americans gained nearly 60 heavy artillery pieces and other military stores. Those guns—transported to Boston by Henry Knox over the winter of 1775–76—were emplaced on Dorchester Heights in early March 1776. The new batteries commanded the British positions and ships in the harbor, making Boston untenable for the British and forcing their evacuation on March 17, 1776.

In short: Ticonderoga supplied the artillery that enabled the Americans to break the stalemate around Boston, and its capture also provided an important morale boost and denied the British a strategic base.
