Whilst there was artillery, it varied in size during the period of the Civil Wars from very small pieces that were little more than enlarged muskets to large pieces firing balls of over 40lbs in weight. In terms of their use there were two broad types: siege guns and field pieces.
The size of the first was such that they were slow moving, relied on civilian transport and were used almost exclusively when a place was besieged. Examples of this type include cannon royal, cannon, demi-cannon, and culverin.
The second were smaller, lighter guns which were therefore easier to move and could be used to support the armies in the field. Examples of this type are Saker, Drake, Minion, Falconet and Robinet. Prince Rupert arrived at Marston Moor with around 50 guns of these types. They could use either ball or case shot which was a way of firing a collection of musket balls in one go. Indeed, there was a type of cannon called a Drake Minion where the breech was bored out. This meant that it could not safely fire ball so was restricted to case shot, but was thereby lighter and could be moved around the battlefield more easily.
