87th Territorial Infantry Division (France)

The 87th Territorial Infantry Division was a WWI-era infantry division of the French Army. It was composed of older reservists from the 10th Military District, headquartered in Rennes. Personnel were generally recruited from Normandy and Brittany.

The alleged first gas attack of the Western Front was launched north of Ypres on 22 April 1915, against its positions (among other divisions) that were occupied by the 73rd and 74th regiments. Chemical weapons had already been used on the Eastern Front and there are some claims that use on the Western Front occurred prior to 22 April 1915.
