With the aim of reducing the St Mihiel Salient formed as early as September 1914, the French carried out an assault at Les Eparges on 17th February 1915.
This assault was immediately followed by German counter-attacks that allowed the latter to regzin the terrain. Bitter fighting was to follow at les Eparges, some on ground level but mainly underground in the mines.
On 9th and 10th April 1915, a battalion from the 8th Infantry regiment seized the eastern outcrop of Les Eparges (Point X). Even so, the fighting at les Eparges was not yet finished.
On 24th April 1915, von Stranz launched a successful attack on Les Eparges at the Calonne Trench. The battles continued over the following months with the same intensity. It was only in September 1918 that les Eparges was truly freed, thanks to 1st American Army offensive that freed the salient.
On 14th September 1918, the Americans reached Fresnes-en-Woëvre: Les Eparges would no longer be in the hands of the Germans.
