French units in World War I

French Army

War diaries all online. No permalinks to individual units, but at least gives a list of unit names.

British Official History includes French order of battle for 1914.

We don't yet have pages for army groups on the Western Front.

Corps Expeditionnaire d'Orient was the French expeditionary force at Gallipoli.

These are probably all of the armies on the Western Front.

These tactical corps have pages. There are probably others that we don't know about.
