Château des Baux in the context of "Siege engine"

A siege engine is a device that is designed to break or circumvent heavy castle doors, thick city walls and other fortifications in siege warfare. Some are immobile, constructed in place to attack enemy fortifications from a distance, while others have wheels to enable advancing up to the enemy fortification. There are many distinct types, such as siege towers that allow foot soldiers to scale walls and attack the defenders, battering rams that damage walls or gates, and large ranged weapons (such as ballistas, catapults/trebuchets and other similar constructions) that attack from a distance by launching heavy projectiles. Some complex siege engines were combinations of these types.

Siege engines are fairly large constructions – from the size of a small house to a large building. From antiquity up to the development of gunpowder, they were made largely of wood, using rope or leather to help bind them, possibly with a few pieces of metal at key stress points. They could launch simple projectiles using natural materials to build up force by tension, torsion, or, in the case of trebuchets, human power or counterweights coupled with mechanical advantage. With the development of gunpowder and improved metallurgy, bombards and later heavy artillery became the primary siege engines.

A battering ram is a siege engine that originated in ancient times and was designed to break open the masonry walls of fortifications or splinter their wooden gates. In its simplest form, a battering ram is just a large, heavy log carried by several people and propelled with force against an obstacle; the ram would be sufficient to damage the target if the log were massive enough and/or it were moved quickly enough (that is, if it had enough momentum). Later rams encased the log in an arrow-proof, fire-resistant canopy mounted on wheels. Inside the canopy, the log was swung from suspensory chains or ropes.

Rams proved effective weapons of war because at the time wall-building materials such as stone and brick were weak in tension, and therefore prone to cracking when impacted with force. With repeated blows, the cracks would grow steadily until a hole was created. Eventually, a breach would appear in the fabric of the wall, enabling armed attackers to force their way through the gap and engage the inhabitants or garrison of the fortified place.

The House of Baux is a noble family from the south of France. It was one of the richest and most powerful families of medieval Provence, known as the 'Race d’Aiglon'. They were independent lords as castellans of Les Baux and Arles and wielded very considerable authority at the local level. They held important fiefs and vast lands, including the principality of Orange.

In Old French: baux (and in Provençal-Occitan, li baou) is the word for 'cliffs, escarpment'. In its use as the family name, it refers to the natural fortress on which the family built their castle, the Château des Baux and the village that surrounded it. The escarpment provided a raised and protected mountain valley that protected their food supply; the natural ridge of the Alpilles allowed control of all the approaches to the citadel of Les Baux-de-Provence and the surrounding countryside, including the passage up and down the Rhone, and the approaches from the Mediterranean. Together, these natural advantages made the fortress impervious to the military technology of the time.
