The Ouvrage de Cindey is located just west of Saint Maurice. It offers very good views at the narrow passage west of the town, but also to hills to north. The Swiss anticipated armoured attacks in these areas. Since Cindey had such a good field of fire it was decided during the modernisation just after WW II to equip it with two 10,5 cm anti-tank guns, one of the most powerful anti-tank guns at those days.

The connaisseur of the Swiss forts will see that the 10,5 cm anti-tank gun actually marries the barrel of the 10,5 cm turret gun model 39 with the standard 10,5 cm casemate mounting. So it also has very heavy recoil cilinders and has a device that loads the shells using compressed air. However there are also some important differences. One of them is the use of compressed air to make the pointing easier and faster. But the most important change was the firing and pointing mechanism. There are two gunners, one for the elevation and one for the direction. When one of the gunner has reached the right elevation or direction he presses a button. The second gunner does the same, once the two buttons are pressed the gun is fired electrically. This way the gun could fire at moving targets.
