By the start of the 1700's the cannon was a common weapon used by European armies, and artillery companies were integral units of the armies almost on the par with the calvary. The third type on engine in the 1700's is the Trebuchets, the largest of the three types of catapults. The Trebuchet consisted basically of a long arm counterweighted to provide sufficient spring, with a leather sling on the opposite end, in which a large stone or another subject of substantial size and weight would be placed.
