Here are some estimates of the maximum ranges of cannons in the 14th century:
Bombards: Bombards were large, heavy cannons primarily used for siege warfare. They fired stone balls and had a maximum range of approximately 1,000 to 1,500 yards (914 to 1,372 meters).
Ribebaults: Ribebaults were smaller, lighter cannons often used in field battles. They fired arrows or small metal balls had a maximum range of approximately 500 to 1,000 yards (457 to 914 meters).
Hand Cannons: Hand cannons were small, portable cannons held and fired by a single person. They had a very short range, typically less than 100 yards (91 meters).
It's important to note that these ranges are approximate and could vary significantly depending on the specific cannon and circumstances. Cannons in the 14th century were not very accurate, and their effectiveness was often limited by the technology of the time.
