Scattershot was used since the earliest days of the cannon. The Hussite Wars saw the peasant Hussites use scattershot since they had limited access to cannonballs. This ammunition was still effective against Medieval [[Knight]]s, who could not block the cannonfire with their armor or shields.
Colonel Henry Knox was ordered to reinforce the Continental Army with cannons during the Siege of Boston. This expedition
is became known as The Noble Train of Artillery and this road (from Fort Crown Point to Boston) became known as The Henry Knox Trail. The cannons were secretly positioned on Dorchester Heights on the night of March 4, 1776; allowing the Continentals to bombard Boston with little opposition. The British abandoned the city on March 17, 1776; unable to counterattack the well fortified Heights. Henry Knox went on to become the chief artillery officer of the Continental Army, and later served as the first United States Secretary of War.
Continental General Nathaneal Greene managed to use guerrilla tactics to outmaneuver the forces of British General Cornwallis in the Southern Theater. Greene's army had lighter equipment than the British forces, guaranteeing that the Continental Army would maintain a mobility advantage. This successful campaign would end with The Siege of Yorktown.
