Final answer:
Henry Knox was responsible for transporting 59 cannons using 42 sleds from Fort Ticonderoga to the Siege of Boston, which helped George Washington force the British evacuation in March 1776.
Step-by-step explanation:
The movement of the 59 cannons and 2,300 pounds of lead from Fort Ticonderoga to the Siege of Boston was an incredible feat accomplished by a team led by Henry Knox. In the winter of 1775-76, Knox used 42 sleds and oxen to transport heavy artillery over 300 miles across challenging terrain to aid General George Washington and the Continental Army. These cannon were then strategically positioned on the heights surrounding Boston, providing Washington with the firepower necessary to break the British control of the city and force their evacuation on March 17, 1776, which is celebrated as Evacuation Day in Boston. This tactical movement highlighted the ingenuity and tenacity of the Colonial forces during the American Revolutionary War.
