7 July XV Corps headquarters decided that the attack on Mametz Wood and Contalmaison should begin with the capture of Quadrangle Support Trench beyond Quadrangle Trench and Pearl Alley. The ground was open and the artillery had difficulty in ranging so an attack at by the 17th (Northern) Division was ordered by Horne, against objections from Pilcher and the brigadiers that the trenches would become untenable under machine-gun fire from Contalmaison and Mametz Wood. A bombardment was fired on the German front line and Contalmaison, increased in intensity for the last ten minutes, during which two 52nd Brigade battalions and one from the 51st Brigade began their advance. The Germans were alert and opened fire under the light of flares behind a defensive barrage. The leading waves were also hit by British shells falling short, found that the German wire was uncut and fell back to the start-line. The 183rd Division took over the front line on the night of Infantry Regiment 183 from Grenadier Regiment 9, Ovillers to Contalmaison and RIR 122 from IR 163, Contalmasion eastwards to the south-west of Mametz Wood; Infantry Regiment
Lehr along the south edge of the wood and Flat Iron Copse, was left behind. Part of the left-hand battalion got into Pearl Alley and some found themselves in Contalmaison, before being driven back from the village and Pearl Alley by IR Lehr and the bombers of GR 9. The Germans tried to extend their counter-attacks from the east of Contalmaison, towards the advanced positions of the 17th (Northern) Division, which were eventually repulsed at about If the night attack failed, the preliminary bombardment from was to continue for another thirty minutes. The III Corps was informed in time for the attack and that the 17th (Northern) Division would try again at the same time. The barrage began promptly and a German counter-bombardment started on the line of the night attack. Communication forward from the 17th (Northern) Division headquarters was so slow that the troops of the 52nd Brigade were late and the barrage had lifted. When the attack began the troops were caught by machine-gun fire from Mametz Wood; the survivors were ordered back apart from a few advanced posts. On the right, a battalion of the 50th Brigade had tried to bomb up Quadrangle Alley but was driven back and a company which tried to move up the west side of Mametz Wood were caught by machine-gun fire from Strip Trench and lost half their number. In the III Corps area on the left flank, the 68th Brigade, 23rd Division was to advance as the 24th Brigade drew level on the right but was delayed by the barrage on Bailiff Wood until when a battalion reached the southern fringe before machine-gun fire from Contalmaison forced them back . The attack on Contalmaison by the 24th Brigade, was to have begun when the 52nd Brigade attacked Pearl Alley again on the right at Mud and communication delays led to the attack not starting until after when two battalions attacked from the south end of Pearl Alley and Shelter Wood on the left. The troops advanced in the open against machine-gun fire and got into Contalmaison up to the church, in which prisoners were taken and counter-attacks by a company of RIR 122 and then a company of GR 9 were repulsed. British artillery-fire on two companies of reinforcements caused them to panic and run away. The attack from Shelter Wood failed because the troops were on lower ground and were slowed by mud and a rainstorm, as machine-gun fire from Contalmaison and Bailiff Wood stopped the attack. The battalion in the village withdrew later in the afternoon after running out of ammunition and hand grenades. An attempt to attack again at was cancelled due to the mud, a heavy German barrage and lack of fresh troops; the 68th Brigade dug in on the west in touch with the 24th Brigade, which faced Contalmaison from the south. XV Corps had ordered the renewal of the attack by the 17th (Northern) and 23rd divisions at but mud delayed the 50th Brigade and its attack was put back to then when two battalions attacked with one from the 52nd Brigade on the left. A 3 Squadron aircraft flew a reconnaissance and dropped a message at that Quadrangle Trench was still full of German troops. All three battalions were caught in the mud and shot down by an artillery barrage and machine-gun fire from ahead and both flanks, losing about by the time the attack was abandoned. The 23rd Division attacked again to close a gap between the 24th and 68th brigades but the troops got into deep mud and were trapped. Later in the day, the 24th Brigade tried to attack Contalmaison but was stopped by machine-gun and artillery fire. On the left, the 19th (Western) Division bombers skirmished all day and at a warning from an observer in a reconnaissance aircraft, led to an advance by German troops towards Bailiff Wood, being ambushed and stopped by small-arms fire.
8 July The 23rd Division was ordered to bomb forward towards Contalmaison and close a gap between the 24th and 68th brigades but trenches were so full of mud that many men were stranded and had to be pulled out. Patrols towards Contalmaison and Bailiff Wood found them still occupied, despite reports that they had been abandoned and the 24th Brigade attacked the village in the evening with the companies which had suffered the fewest casualties the day before. The attack was repulsed by machine-gun fire and artillery-fire; a battalion trying to advance from Peake Woods, midway between Shelter Wood and the village, to join with the 68th Brigade, was also defeated. Another 3 Squadron aircraft was aloft to watch the attacks and reported that when the British barrage began rockets were fired from the German trenches, which brought forth from German artillery batteries a wall of fire from Bottom Wood to Bailiff Wood, west of Contalmaison. The crew flew behind the German barrage and saw no German troops in Quadrangle Trench until when men in field grey suddenly appeared to a traverse and repulsed the attack. IR 183 was ordered to attack III at midnight but the rain delayed preparations and the attack eventually began at after dawn had broken. Observers of the 34th Division saw the Germans and directed artillery and machine-gun fire on the attackers, preventing them from advancing.
9 July On 9 July, the 24th and 68th Brigades of the 23rd Division spent the morning trying to improve their positions south and west of Contalmaison, ready for a bigger attack by the 69th Brigade on 10 July. Indications of a German counter-attack from the village were followed by bombardment of the 68th Brigade front, which caused many casualties since the trenches were shallow and crowded with men. A German attack was rapidly dispersed by small arms and artillery fire. A battalion of the 24th Brigade established a machine-gun nest in a commanding position south of the village and patrols of a 68th Brigade battalion entered Bailiff Wood, before being shelled out by British artillery. An attempt to return at was forestalled by a German counter-attack by parts of II Battalion and III Battalion, IR 183 of the 183rd Division at to reinforce the line between Contalmaison and Pozières but was repulsed with many casualties. The preliminary bombardment had been fired but when the delayed attack began at no artillery preparation was possible, because telephone contact with the artillery had been cut off. Two companies fought their way into the wood and the trenches either side. On the right a trench block was built and a German counter-attack repulsed. The 17th (Northern) Division attacked Quadrangle Support Trench early in the morning and again at midday by bombing up trenches but took very little ground. A surprise attack from Quadrangle Trench, by a battalion of the
50th Brigade and one of the
51st Brigade, plus attached bombers, was attempted at On the right flank, German small-arms fire halted the attack by only 40 men, which was then reinforced by two companies from the 50th Brigade but the survivors were forced back to the start line. On the left, the 51st Brigade captured the west end of Quadrangle Support Trench and pressed on towards Contalmaison, destroying the 11th Company, RIR 122. Germans at the west end built a barricade covered by a machine-gun but troops of the 8th South Staffords and the 7th Lincolns advanced either side of Pearl Alley towards Acid Drop Copse and stopped when they realised that there were no British troops on the flanks. The 10th and 12th companies of III Battalion, IR 183 continued to resist attempts by the 50th Brigade to advance and the parties on the left were ordered to retire before dawn, except for a machine-gun team near the copse which were overlooked, the battalion losing By late on 9 July, II and III battalions, IR 183 held the (Cable Trench) and (Forester Trench) and I Battalion was in reserve at Pozières; the I Battalion, RIR 122 garrisoned Contalmasion and the to the west, the III Battalion held Quadrangle Support and Wood Support and the II Battalion was in reserve in the second position behind Contalmaison Villa. The 5th Company, II Battalion was sent to reinforce the 9th Company in Wood Support, which had lost of its men in a bombardment. Another company was sent into Mametz Wood, leaving only the 6th and 7th companies left in reserve. II Battalion, IR Lehr remained along the south side of the wood and Flat Iron Copse, with the III Battalion in reserve around Bazentin le Petit.(The defence of this part of the German front had been conducted by 15 battalions on 1 July (BRIR 6, IR 62, RIR 109,110 and 111) and from 2 July, troops from the 12th Reserve Division, elements of the 185th, 12th, 10th Bavarian and 3rd Guard divisions and IR 163 of the
17th Reserve Division had joined the defence; the 183rd Division was en route to the Somme front.)
Night reinforcement At dawn, the 6th Company of RIR 122 arrived in Quadrangle Support, after a fraught night march. Köstlin had received the order in the afternoon of 9 July and took the company back to Martinpuich for supplies and ammunition but the field kitchen draught horse bolted from a shell with the field kitchen. Ammunition took until after midnight to issue and then the company moved forward, with two machine-guns. Two guides had been sent back from the III Battalion but it was so dark that Köstlin went cross-country on a compass bearing. The column lost cohesion in the dark between Martinpuich and Bazentin because of the number of shell-holes and trenches to traverse and the halts to form up took too much time. Köstlin formed the company into columns of sections after passing over the second position and the advance quickened. The ground was under shellfire and casualties began to increase. Köstlin decided to avoid Mametz Wood and move in the open between the wood and Comtalmaison on the line of the (Grand Duke Trench, Pearl Alley to the British) to Quadrangle Trench and then to the wood from Quadrangle Support. As they crossed the Contalmaison–Bazentin road at as dawn was breaking, Köstlin sent the guides forward who took twenty minutes to get back and report that the trench was straight ahead. As the company advanced, a machine-gun opened fire from the right and caused much confusion. Köstlin shouted "Double march, into the trench in front" but it was another further on and only thirty men followed him, the rest retreating in confusion to the second position or taking cover.
10 July Lambert and the battalion commanders of the 69th Brigade reconnoitred the ground and arranged support from the artillery of the 23rd and 34th divisions. Two battalions assembled along Horseshoe Trench, in a line long, facing Contalmaison away to the east. Two companies were sent forward to Bailiff Wood, to make a flank attack on the north-west end of the village. After a thirty-minute bombardment from the artillery firing from the south increased the rate of fire as the infantry closed on the village; a creeping barrage moved in five short lifts, from the trench around the west side of the village to the eastern fringe. A smoke screen failed as insufficient ammunition could be carried forward in time but the attack was supported by every machine-gun in the division, firing on the edges of the village and its approaches. The infantry moved forward in four waves, with mopping-up parties following, through return fire from the garrison, uncut wire on the right causing a delay and then reached a trench at the edge of the village, forcing the survivors to retreat into Contalmaison. The waves broke up into groups and advanced faster than the barrage but the divisional artillery commander was able to speed up the creeping barrage. The village was overrun despite determined opposition from parts of the garrison, one British battalion losing and taking from RIR 122. The Germans in the village were from I Battalion, RIR 122 but casualties had reduced the battalion to fewer than Small detachments got into the village to reinforce but casualties from British artillery were constant and the village was reduced to rubble. The final bombardment beginning at broke the resilience of the garrison and about ran back to Bazentin and Pozières. Other troops took refuge in the remaining dugouts in the (Emperor Trench west of the village, Quadrangle Trench to the British) and in village cellars. The alarm was raised at but only emerged from cover in the 3rd and 4th Company area at the west side of the village. Little could be seen through the smoke and dust but German artillery was able to engage the British advancing from the west. The battalion that was delayed at the garden hedge was engaged by the German party still willing to resist, which inflicted about but failed to stop the advance. The commander of I Battalion, RIR 122 was captured at the château, and prisoners being taken, 69th Brigade casualties being The troops of the 2nd Company in the south-eastern part of the village were trapped and a counter-attack towards the road junction south of the church was defeated. The company retreated along Pearl Alley, a rearguard holding the Cutting until dark fell. The survivors of the 6th, 10th, 11th and 12th companies in Quadrangle Support Trench were enveloped on three sides and reduced to drinking muddy water from the trench bottom but no attack came. After dark a diversion was staged and the garrison retreated to the second position, making it back despite being fired on as they approached the position. IR 183 counter-attacked III (Fourth Street) again at but collided with the 111th and 112th Brigades of the 34th Division, co-operating with the 69th Brigade attack on Contalmaison. The 111th Brigade was forced back to III with having taken and the 112th Brigade gave ground until a battalion made a bayonet counter-attack. The IR 183 report blamed fire on the left flank and rear, from the British who had got into Contalmaison, as the Germans reached the and at the regiment was ordered to retire to and trenches and hold Pozières at all costs. The flank attack on the north end also reached its objective, met the main attacking force at and sniped at the Germans as they retreated towards the second position; only of the I Battalion, GR 9 making it back. The village was consolidated with the help of an engineer field company inside a
box barrage, maintained all night and a large counter-attack was repulsed by bombers at Two more field companies were delayed by German artillery-fire and then by congestion and took until morning to arrive. The troops of the 23rd Division began to be relieved by the
1st Division (Major-General
Peter Strickland).
11 July By dawn, IR 183 had completed a retirement to and trenches, having lost about and in the centre, RIR 122 was back in the second position from Pozières to Bazentin le Petit behind a screen of machine-gun posts north of Mametz Wood and extending towards Contalmaison, having lost in two days but IR Lehr was still holding Flat Iron Copse. By noon on 11 July, the 23rd Division was relieved by the 1st Division, having lost up to 10 July. The German positions between Mametz Wood and Contalmaison, were captured by the 17th (Northern) Division, after they were outflanked by the capture of the village and the southern part of the wood, although bombing attacks up trenches on 9 July had failed. At a surprise bayonet charge was attempted by a battalion each from the 50th and 51st brigades, which reached part of Quadrangle Support Trench on the left but eventually failed with many casualties. After the capture of Contalmaison next day, an afternoon attack by part of the 51st Brigade advanced from the sunken road east of the village, to Quadrangle Support Trench. Parties of the 50th Brigade attacked westwards up Strip Trench and Wood Support Trench, against German defenders who fought hand-to-hand, at great cost to both sides, before the objective was captured. Touch was gained with the
38th (Welsh) Division in the wood and the 23rd Division in the village, before the 21st Division took over early on 11 July; the 17th (Northern) Division had lost since 1 July. ==Aftermath==
