Haxo Casemate

Adapted from Aide-Memoire to the Military Sciences, Pt. I, Vol. II, "Fortifications, Permanent," Plate VINamed after French engineer François Haxo who developed this particular type of casemate. A Haxo Casemate, sometimes called a Haxo Battery, was an embrasured and vaulted masonry casemate laid into the parapet of permanent fortifications. Masonry of the casemate was shielded from hostile artillery and small arms fire by a thick layer of earth  which would absorb the shock of shot and shell impacts and prevent the masonry vault from broken down. Haxo Casemates were developed specifically for bastion system fortifications in response to the need to preserve defensive artillery fire into the final stages of a siege by protecting guns positioned on bastion faces from vertical, direct, and ricochet fire.
