What is the real history of these war machines?
Actually, we don't have a lot to go on. At the end of the 19th century, the nobleman and amateur historian Ralph Payne Gallwey wrote a book about the crossbow, and in it he describes the "catapult", what modern historians call a mangonel or onager. Unfortuantely, we now know that most of his sources are fiction. He even invented fake reference numbers for them at the Bibliothec National in Paris, France. The books of Violet Le Duc (1814-70) were also a large influence on Gallwey, however Violet's machines are pure invention. Below is the most detailed description of the Mangonel to survive the ages.

For the equine species, see Onager. Sketch of an Onager, from Antique technology by Diels. The onager's framework is made out of two beams from oak, which curve into humps. In the middle they have quite large holes in them, in which strong sinew ropes are stretched and twisted. A long arm is then inserted between the bundle of rope, at its end it has a pin and a pouch. The onagers of the Roman Empire were mainly used for besieging forts or settlements. In the Middle Ages (recorded from around 1200) a less powerful version of the onager was used that held the projectile(s) in a fixed bowl instead of a sling. It derived its name from the kicking action of the machine, similar to that of an onager (wild ass). Caerphilly castle. LEGO Mindstorm Activities.
