The order of the battle of the French Army in August 1914 was planned according to the mobilisation and concentration
Plan XVII and applied on 2 August 1914, the day before the
German Empire declared war.
The order of battle is similar to the
German Army with several armies each having army corps of two infantry divisions, with a number of reserve units at the disposal of the Commander in Chief and Minister of War. The organisation changed during August with the assignment of new reserve units and the creation of new armies.
Organisation
Peacetime Organisation
The peacetime army had, in the spring of 1914, a strength of 882,907 men, with 686,993 in metropolitan France, 62,598 in Algeria and Tunisia, 81,750 in Morocco, and 51,566 auxiliaries. [1]
The territory of the French Republic was divided into 21 military regions, 20 in metropolitan France, and one in Algeria (the 19th). Each region provided two infantry divisions, except the 6th which had three divisions.
The army had 686 infantry battalions. Metropolitan France had 173 infantry regiments, each with three battalions (nine regiments had four), as well as 31 light infantry (
French: chasseur à pied) battalions, and 12 colonial infantry regiments (each with three battalions). In the colonies, there was four regiments of
Zouaves with six battalions, 9 regiments of Algerian riflemen (
French: tirailleurs algériens) with 40 battalions, 2 regiments of the Foreign Legion with six battalions, 5 battalions of African light infantry, 6 Moroccan colonial
marching regiments, and 5 battalions of Moroccan auxiliaries.
The cavalry had 378 squadrons, organised into 89 regiments (each with four squadrons): 12
cuirassier, 32
dragoon, 21 light horse (
French: chasseur à cheval), 14
hussar, 6 African light horse, and 4
Spahis.
The artillery had 855 batteries (each of four guns), organised into 62 field artillery regiments, 2 mountain artillery regiments, 11 foot artillery regiments, 5 heavy artillery regiments, 10 African artillery groups, and 3 colonial artillery regiments. It provided 42 divisional artillery (with three groups or nine batteries), 20 corps artillery (with four groups or twelve batteries), and 10 horse groups (with three batteries).
Mobilisation
The French army began mobilising on August 2, 1914 according to
Plan XVII. The 680,000 peacetime troops were joined by 2,900,000 reservists and territorials. The three youngest classes of reservists were used to bring active units up to wartime strength, while new units were created from older reservists and territorials.
Each of 21 military regions provided an army corps of two infantry divisions. Each corps was numbered after the military region it was created from. The 19th region in Algeria did not form a corps, but did send its two divisions. A total of 46 infantry divisions were mobilised with 1,054,000 men, and 10 cavalry divisions with 52,500 men.
Each infantry division is composed of two infantry brigades with two regiments, plus a cavalry squadron, an artillery regiment (with three groups) and an engineer company. Each cavalry division is made up of three brigades with two regiments, plus a cyclist group, an artillery group and a detachment of cyclist engineers. Each army corps is made up of two infantry divisions (except the 6th corps with three divisions) with corps troops of a cavalry regiment (with four squadrons), an artillery regiment (with four groups), and an engineering battalion (with four companies).
Then, reserve infantry regiments are formed from the active regiments. They are given the same number as the active regiment plus 200. Reserve infantry regiments had two battalions, compared with three for the active regiments. These are grouped into 25 reserve infantry divisions numbered from 51 to 75 (numbered after their military region plus 50). These reserve divisions had a total of 450,000 men.
The active and reserve regiments are each created from roughly 50/50 active and reserve personnel. To show this continuity, the active battalions were numbered 1, 2, and 3, while the reserve battalions were numbered 5 and 6.
The oldest were placed into territorial infantry regiments with three or four battalions, some of which were used to create 12 territorial infantry divisions with 184,600 men.
1,525 infantry battalions (642 active, 406 reserve and 410 territorial), of approximately 1,100 men (with four companies of 254 men);
545 cavalry squadrons (316 active, 176 reserve and 37 territorial) of approximately 120 men (in four platoons of 30 cavalrymen);
1,468 artillery batteries (1,042 active, 265 reserve and 161 territorial), each of four guns (a group usually has three batteries);
508 engineering companies and detachments.
Added to the 95 active, reserve and territorial divisions with 1,681,100 men are the army troops of 187,500 men, garrisons of 821,400 men, depots of 680,000 men, and railway guards of 210,000 men. [3]
Order of Battle
First Army
The
First Army (
French: 1re Armée) was commanded by General
Auguste Dubail. In August 1914 it constituted the right wing of the French Army, concentrated between Remiremont and Charmes, with the mission of attacking towards Mulhouse and Sarrebourg. Its strength on mobilisation was 7,588 officers, 258,864 NCOs and men, and 92,106 horses organised into five corps of ten infantry divisions, and two cavalry divisions. [4][5]
The
Second Army (
French: 2re Armée) was commanded by General
Édouard de Castelnau. In August 1914 its major role in the campaign plan was to liberate Lorraine and attack into Germany. It was concentrated between Pont-Saint-Vincent and Neufchâteau, with the mission of attacking towards Morhange. Its strength on mobilisation was 9,391 officers, 314,804 NCOs and men, and 110,062 horses organised into five corps of ten infantry divisions, three reserve infantry divisions, and two cavalry divisions. [23][24]
The
Third Army (
French: 3re Armée) was commanded by General
Pierre Ruffey. In August 1914 it was concentrated between Saint-Mihiel and Verdun, with the mission of holding the Germans in their defensive positions before Metz. Its strength on mobilisation was 6,786 officers, 230,471 NCOs and men, and 80,381 horses organised into three corps of seven infantry divisions, three reserve infantry divisions, and one cavalry division. [46][47]
Companies 6/11, 6/17, and 6/22, 3rd Engineer Regiment
Transmission Detachment, 8th Engineer Regiment

Fernand de Langle de Cary. In August 1914 it was concentrated between Saint-Dizier and Bar-le-Duc, with the mission of being held in reserve in the Argonne Region. Its strength on mobilisation was 4,689 officers, 154,899 NCOs and men, and 58,491 horses organised into three corps of four infantry divisions, two colonial infantry divisions, and one cavalry division. [63][64]
The

Charles Lanrezac. In August 1914 it was concentrated between Hirson and Dun-sur-Meus, with the mission of guarding the border with Belgium. Its strength on mobilisation was 8,886 officers, 290,464 NCOs and men, and 108,360 horses organised into five corps of ten infantry divisions, two reserve infantry divisions, and one cavalry division. [75][76]
Formations at the disposal of the Chief of the General Staff
In addition to the five field armies, the Chief of the General Staff, General
Joseph Joffre had several large formations at his disposal on other fronts, or as a reserve.
The Army of the Alps was formed from units mobilised in the 14th (Lyon) and 15th (Marseille) military regions to defend the border with Italy, who was a member of the Triple Alliance with Germany and Austria-Hungary.
Plan XVII provided for several large units to be at the disposal of the Minister of War,
Adolphe Messimy. These units were gradually transferred to the Chief of the General Staff, General
Joseph Joffre.
Six territorial infantry divisions were initially used to provide defence of the north-east coast from possible German naval landing, and to guard the Spanish border. As these threats receded, these divisions were gradually moved towards the frontline.
