During the winter of 1775-1776, Henry Knox marched from Boston to Fort Ticonderoga, collected 50 tons of cannons and other armaments and transported the weapons back to Boston. Knox and his men sailed down Lake George and then the Hudson River to Albany. They transported the weapons from Albany to Boston by ox-drawn sleds where the artillery was used to fortify Dorchester Heights, helping to end the Siege of Boston. The 300 mile (482 km) trek took 56 days. - AsNotedIn
