Were cannons used in the Revolutionary War?

World War 1,2 and on pirate ships! During the American Civil War, cannons were used in many applications. Forts were built to protect the coast and were armed with very large cannons. Ships also carried cannon of large caliber including river boats that could travel the Mississippi and Tennesse Rivers to attack river forts. In the field, smaller cannons were used on carriages. There was also a "mountain howitzer" that could be easily transported by horse. Where were they used? Every battle had cannons. At the Battle of Shiloh in April 1862, the Confederates lined up 66 field guns to fire into the Hornet's Nest---this was the most numerous cannons used in a battle on North America at that time.
