Historic and technical information
Denomination :     75 Mle 1897 de casemate Origin :       ( Arsenaux de l'Etat)          

Historic context :

In 1889 the pioneers Commandant Laurent designed the forts flanking casemate concept. This designe inherited the name of 'Casemate de Bourges' following the experiments that took place in 1899 in the French town with the same name. The role of this fortification element was to protect the sides of the forts as well as the intervals of the fortified rings. Their openings were not facing the enemy side, in order to protect the guns from a front enemy fire.

First equipped with two 95 mm Lahitolle guns on coastal carriage; they were quickly given two guns of a variant of the famous and brilliant 75 mm fieldgun. This 'Canon de 75 Mle 1897 de casemate' was built with the same barrel, the same breech, the same recoil recuperating system than the fieldgun. The casemate carriage was made with a truncated trail resting on small wheels at its both ends, beams linking it to a front pivot, and a steel shield. A rail was attached to the casemate roof to assist the barrel change manoeuvre.

DIn this configuration, the gun needed a 15 men crew. 92 such guns were placed into 46 casemates in August 1914
