Which was a reason the capture of fort ticonderoga was important for the colonist?

In 1775 when the American Revolution began, the British and Americans had one of the most important battles at Fort Ticonderoga. Here the British Military base was attacked, and the capture of the fort became the first American victory. It boosted the morale of the Continental Army and would be a significant factor in the outcome of the revolution.
The colonists hoped that Fort Ticonderoga could stop the British Army from proceeding to the South.
The Fort had critical importance ranging from Ammanents that Americans had short of supply and had a collection of massive artillery (howitzers, cannons, and mortars). 
The Forts location at the shores of Lake Champlain was also a strategic route to the British controlled provinces in the North and route along the thirteen colonies.
