British plan The British plan was for an advance to the final objective set for the attacks of during the Battle of Flers–Courcelette. The ground to be taken was on the east side of Bazentin ridge, which ran north-west from the Somme to a hollow facing north-east with Combles at the west end. North of the hollow, lay Morval, Lesbœufs, Gueudecourt and the Albert–Bapaume road. Spurs ran down the eastern slope generally to the north-east, in the direction of the Péronne–Bapaume road, before the ground rose again from St Pierre Vaast Wood to Sailly-Saillisel, Le Transloy, Beaulencourt and Thilloy. An advance on the main front of the British attack of , was to be made in three stages. The first stage was an advance to the third of the objective lines set for 15 September and to the Gird Trenches () south of Gueudecourt, beginning at The second objective was along a line along the sunken road from Combles to Gueudecourt to the west of Morval and Lesbœufs, then over a spur south-east of Gueudecourt and through the centre of the village, beginning at The final objective was on the east side of Morval, Lesbœufs and Gueudecourt, the advance to begin at with the objectives to be reached by Tanks were to be kept in reserve, ready to assist the attack on the villages at the final objective. The open ground on the approach to Gueudecourt was also considered to be too dangerous for tanks. Two brigades of the
1st Indian Cavalry Division were to move forward to Mametz, with all the division to be ready to advance on Thilloy and Ligny Thilloy, once Lesbœufs and Gueudecourt were captured. If the villages were taken before small cavalry detachments attached to XIV and XV corps were to exploit local opportunities. The British conformed to the French preference for afternoon attacks, which meant that the final bombardment took place in daylight. The 21st Division (Major-General
David Campbell), was to capture Gueudecourt by advancing to the first objective at the Gird Trenches and then reaching the second objective at the village and passing through to the final objective beyond. Morale in the
21st Division had declined and on 24 September, of the 10th
King's Own Yorkshire Light Infantry (KOYLI) tried to report sick. The right flank of the division was to join with the
Guards Division at a fork on the Gueudecourt–Le Transloy road.
German preparations In early September,
Crown Prince Rupprecht of Bavaria, commander of the German northern army group, found that frequent relief of troops opposite the British was essential and stripped the other armies of the army group of fresh divisions and units, moving the 85th Reserve Brigade and the 45th Reserve Division from the 4th Army in Flanders, into the area between Thiepval and Martinpuich. After the sacking of
Erich von Falkenhayn, the Chief of the General Staff of
Oberste Heeresleitung (OHL) on 29 August, his successors General
Paul von Hindenburg and General
Erich Ludendorff visited the Western Front, ordered an end to offensive operations at the
Battle of Verdun and the reinforcement of the Somme front. Tactics were reviewed and a more "elastic" defence was advocated, to replace the defence of tactically unimportant ground and the routine counter-attacking of British and French advances. After the Battle of Flers–Courcelette, all of the divisions from Combles to Thiepval had to be relieved and the defences around Gueudecourt were taken over by the
6th Bavarian Division and the
52nd Reserve Division. Gird Trench and Gird Support Trench , apart, had been dug by the Germans against an attack from the south-west. The Gird trenches ran north-west to south-east, behind the Butte de Warlencourt. Seven Dials and Factory Corner protected the village against attacks from Eaucourt l'Abbaye to the west. On the road north-west to Ligny–Thilloy, Luisenhof Farm had been fortified. ==Battle==
