The Battle of Arras (also known as the First Battle of Arras, was an attempt by the French Army to outflank the German Army, which was attempting to do the same thing during the "Race to the Sea", their reciprocal attempts to exploit conditions created during the First Battle of the Aisne. At the First Battle of Picardy each side had attacked expecting to advance round an open northern flank and found instead that troops had arrived from further south and extended the flank northwards.

The Tenth Army (General Louis Maud'huy) attacked advancing German forces on 1 October and reached Douai, where the 6th Army (Crown Prince Rupprecht) counter-attacked, as three corps of the German 1st, 2nd and 7th armies attacked further south. The French were forced to withdraw towards Arras and Lens was occupied by the Germans on 4 October. Attempts to encircle Arras from the north were defeated and both sides used reinforcements to try another flanking move further north at the Battle of La Bassée The reciprocal flanking moves ended when both sides reached the North Sea coast and then tried breakthrough attacks during the First Battle of Flanders.

Background

Strategic developments On 28 September, Falkenhayn ordered that all available troops were to be transferred to the 6th Army for an offensive on the existing northern flank by the IV Corps, Guard Corps and I Bavarian Corps near Arras, an offensive by (HKK2, also II Cavalry Corps) on the right flank of the 6th Army, across Flanders to the coast and an acceleration of the operations at the Siege of Antwerp, before it could be reinforced. Rupprecht intended to halt the advance of the French on the west side of Arras and conduct an enveloping attack around the north of the city.

Prelude

Battle of Albert, 25–29 September

On 21 September Falkenhayn had decided to concentrate the 6th Army near Amiens, to attack westwards to the coast and then envelop the French northern flank south of the Somme. The offensive by the French Second Army forced Falkenhayn to divert the XXI Corps and I Bavarian Corps as soon as they arrived to extend the front northwards from Chaulnes to Péronne on 24 September and drive the French back over the Somme. On 26 September, the Second Army dug in on a line from Lassigny to Roye and Bray-sur-Somme and German cavalry moved north, to enable the II Bavarian Corps to occupy the ground north of the Somme. On 27 September, HKK 2, drove back the 61st and 62nd Reserve divisions (General Joseph Brugère), who had replaced General Albert d'Amade, to clear the front for the XIV Reserve Corps to link with the right flank of the II Bavarian Corps. The French began to assemble at Arras and Maud'huy found that instead of making another attempt to get round the German flank, the was menaced by a German offensive.

The II Bavarian Corps and XIV Reserve Corps, pushed back a French Territorial division from Bapaume and advanced towards Bray-sur-Somme and Albert. From the French XXI and X corps north of the Somme, with support on the right flank by the 81st, 82nd, 84th and 88th Territorial divisions (Brugère) and the 1st, 3rd, 5th and 10th Cavalry divisions of the Cavalry Corps (General Conneau) to the south-east of Arras, defended the approaches to Albert. On 28 September, the French were able to stop the German advance, on a line from Maricourt to Fricourt and Thiepval. The German cavalry was stopped near Arras by the French cavalry. On 29 September, Joffre added X Corps which was at Acheux, north of Amiens, the Cavalry Corps which was south-east of Arras and a provisional corps under General Victor d'Urbal, of the 70th and 77th Reserve divisions, one in Arras and the other in Lens, to the new Tenth Army.

Battle

30 September – 1 October

A French division arrived at Arras on 30 September and repulsed a German attack at the Cojeul river and high ground near Monchy-le-Preux on 1 October. The French were then slowly pushed back from Guémappe, Wancourt and Monchy-le-Preux, until the arrival of X Corps. The French XI Corps was withdrawn from the Ninth Army and sent to Amiens; by 1 October two more corps, three infantry and two cavalry divisions had been sent northwards to Amiens, Arras, Lens and Lille, which increased the Second Army to eight corps, along a front of . Joffre ordered General Édouard de Castelnau to cease attempts to outflank the Germans opposite and operate defensively. From the northern corps of the Second Army and the Territorial and cavalry divisions nearby, Joffre created a under the command of General Louis Maud'huy. The advanced on Arras, with the gap south to the Second Army, held by the Territorial divisions. Maud'huy was ready to begin an attack to the south-east past Arras and Lens, under the impression that the was opposed only by a cavalry screen, rather than three German corps which were preparing to attack.

The westward advance of the XIV Reserve Corps, from Bapaume to Albert and Amiens, was stopped by French troops east of Albert. Five German cavalry divisions, further north, were also confronted by French cavalry and infantry, while attempting to guard the northern flank of the XIV Reserve Corps. French reinforcements increased the possibility of a reciprocal French outflanking manoeuvre. Agents reported the massing of French and British troops between Arras and Lille and that the railways between Lille, Douai and Arras had been protected by an outpost line, from Orchies to Douai and Arras. The 1st Guard Division and IV Corps were moved to the northern flank of the XIV Reserve Corps, to allow some of the cavalry divisions to redeploy. The I Bavarian Reserve Corps (General Karl von Fasbender), was withdrawn from Lorraine and moved to Cambrai and Valenciennes, intended to advance from Douai, in another attempt to outflank the French. The corps began to reach Artois on 30 September and before noon was ordered to advance with all of the units which had arrived, to reach Douai before dark. Five battalions of the 1st Bavarian Reserve Division advanced north-west from Cambrai and parts of the 5th Bavarian Reserve Division left Denain heading westwards, also for Douai.

The 5th Bavarian Reserve Division advance was stopped by French troops at Lewarde, short of Douai, until the village was captured in the evening, after which the division stopped for the night. The 1st Bavarian Reserve Division battalions also came within of Douai, after overcoming French troops at Cantin and Raucourt. Behind the advanced battalions, the rest of the corps arrived during the day. Both divisions were ordered to capture the town next day and occupy high ground to the west. The inner units were to pin down French troops in Douai, as the flanking units encircled the town and met at Esquerchin to the north-west. The envelopment failed, due to the distance to be travelled and the resistance of French skirmishers, which delayed the German advance. Douai was captured by nightfall and prisoners were collected by 2 October, mainly from Territorial regiments. Allegations that civilians had fired at German troops, led to the town being fined The Guard, IV and I Bavarian corps assembled on a line from Arras to Douai, opposite the Territorial divisions of General Brugère and attacked on 1 October, forestalling the attack being prepared by the .

2 October

The advance resumed on 2 October, with the 1st Bavarian Reserve Division in the south, attacking through Brebières to St Laurent and the 5th Bavarian Reserve Division to advance via Izel and Oppy to Bailleul-Sir-Berthoult. It was known that the French 70th Reserve Division was moving south-east, also towards Bailleul and Lens. The French advanced with a left flank guard facing Douai, to link with the 77th Division at Gavrelle and Fresnes. The French divisions had been rushed from the Vosges and were also deployed at short notice. A brigade of the 70th Reserve Division moved towards Fresnes and one advanced south-west to Gavrelle, ready to pause on 2 October and then push outposts southwards. The French moved south in parallel brigade columns, as the Germans moved west in divisional columns.

Bavarian Reserve Infantry Brigade 9 of the 5th Bavarian Reserve Division, reached Esquerchin and set flank guards facing north, before advancing on Quiéry la Motte, when French artillery near Izel pinned down the German infantry and destroyed a German artillery battery. French infantry then attacked from Drocourt and forced the German columns to deploy and work forward closer to Izel, to try to overrun the artillery. Bavarian Reserve Infantry Brigade 11 advanced on Beaumont, Drocourt and Bois-Bernard, moving the rearguard round to the right flank, which arrived just in time to meet a French attack from Hénin Liétard. Both German brigades attacked again and captured Izel, the heights east of Bois-Bernard and Beaumont Station. Later in the evening Drocourt and Fresnoy were captured and Bois-Bernard was entered, being captured by dawn on 3 October.

3 October By the morning of 3 October, the German front line ran from Drocourt to Bois-Bernard and Fresnoy. To the south-east, Bavarian Reserve Infantry Brigade 9 attack on Neuvireul was repulsed by small-arms and heavy artillery-fire from Acheville. The brigade dug in between Izel and Neuvireul. In the 1st Bavarian Reserve Division area to the south, the advance was at first protected on both flanks and advanced to Fresnes unopposed. The advance on Arras continued, supported by artillery moved forward during the night and the Guard, 4th, 7th and 9th Cavalry divisions in the Scarpe valley. The cavalry was to cover a westwards move of the Bavarian divisions, the 5th towards Vimy and Thélus and the 1st to Thélus and St Laurent. The cavalry were slow to move and the Bavarian infantry were held up by attacks from the north, until the cavalry arrived during the afternoon. Bavarian Reserve Infantry Brigade 9 managed to capture Méricourt after the 9th Cavalry Division arrived, which enabled the rest of the 5th Bavarian Reserve Division to advance and capture Rouvroy and Acheville. Around French patrols slowed the advance and the 5th Bavarian Reserve Division put flank guards out on the right for the advance on Gavrelle. French troops in Oppy engaged the Germans with small-arms and artillery-fire, which delayed the Germans until the success of a costly attack against Oppy and Neuvireuil.

Costly German attacks were made on Beaurains, Mercatel and the Arras suburbs of St Laurent-Blangy and St Nicolas, which were repulsed and forced the Germans to move northwards. An evening attack by three battalions on Arleux failed, which left the French position from Arleux to Bailleul and Point de Jour intact. More orders arrived to press the advance and an improvised , took over flank protection to the north and responsibility for the advance from Méricourt to Avion; was ordered to capture Vimy. The flank attack by the French 70th Reserve Division had been repulsed but the advance reached only Drocourt and Gavrelle instead of St Laurent and Bailleul. The disorganisation in the 5th Bavarian Reserve Division, which had been caused by the urbanised landscape and the vigour of the French defence, was not remedied by the groups and worsened on 4 October. The right flank of X Corps of the and left flank of the Territorial divisions to the south became separated, prompting Castelnau and Maud'huy to recommend a retreat.
