Battle of the Somme 6 - August 1st to September 25th

September 1916

The battle ground on remorselessly. Heroic British and Empire assaults met heroic German defences. It is interesting that Churchill is far more critical, in terms of losses and failed strategy, than Buchan, who was at the time employed to write propaganda articles for the press (I’ve read them [and his reports on Jutland] – toe-curlingly partial). Out of government and without his usual influence, Churchill was far more disparaging than in his writings on Gallipoli, where he had been responsible.

“The battlefields of the Somme were the graveyards of Kitchener’s army. The flower of that generous manhood which quitted peaceful civilian life in every kind of workaday occupation, which came at the call of Britain…. and the most remote parts of her Empire, was shorn away for ever in 1916.”   (WS Churchill. The Great War p922) 

He was particularly active in a campaign to quash the official line that German losses in the first month were considerably greater than British losses (he was right, the opposite was true). As we have seen, the slow progress and the considerable cost of the battle were causing major concerns back home.

In early August great heat returned, but after a quiet three days, the assault on Pozieres was resumed, and by the 6^th the Windmill, highest point of the ridge, was taken along with some further ground to the north and east. At last the British held control of significant high ground, and could survey the rolling countryside eastwards to Bapaume. The fierce battle to take Mouquet Farm continued, between Pozieres and Thiepval. To the south, pincer pressure on Guillemont was brought to bear by the addition of French attacks from further south.

There seems little doubt that the German defences had begun to wilt by this stage. Heavily outnumbered in men from the start, and hardly free at any time from remorseless British artillery, German contemporaneous accounts reveal serious strain. They had carried out numerous counter-attacks to reclaim their lost trenches and positions, with a corresponding rise in their casualties. Increasingly their reserves were drawn from a hotch-potch of Divisions, and the disciplined cohesion of defensive units was weakened.

On August 18^th another combined attack across the whole front was launched. The British had learned some lessons about the German defence, and this time they had their first taste of success at Thiepval – taking, and retaining control of the Leipzig redoubt. Small gains were made along the line, so that the  British now held most of the German second positions. The 24^th saw another push that brought Thiepval village itself within 500 yards. Over the next week, the Germans threw some of their best reserves into fierce counter-attacks, especially at Thiepval, Mouquet farm and High Wood. Their improved ability to withstand these counters gave the now hardened British infantry an important morale boost, and German losses were high.

On 3^rd September, after another short breather, the British line surged again. By the end of the day they had consolidated their positions along the whole German second line from Mouquet farm to the junction with the French. They were still unable to make progress from Thiepval northwards. On the other flank the French were going from strength to strength. A new 10^th Army under General Micheler rushed forward south of the river, but moved north to help in the capture of Guillemont, and on towards Combles (see map). All German counters were held, and by 10^th September this new front line was secure. This incremental progress north of the river, made at great cost, was on a relatively narrow front, and was likely to become an unsustainable salient. Accordingly Haig now issued orders to prioritise more lateral progress – aimed at the final capture of Mouquet farm on the left, and more tellingly, to join the French lines beyond Guillaumont and Ginchy.

Although the Germans had now lost all their second lines of defence south of Thiepval, they had been busy strengthening their third line positions and creating a fourth system, roughly on a line Courcelette, Martinpuich, Flers, Lesboueufs and Morval (see map). They had reorganised their chain of command, reconstituting their I army (von Below) north of the river, with the II army (Gallwitz) south of it. Reserve armies behind created an army group, put under the direction of Crown Prince Rupprecht.

Overall, the Allies were in a more optimistic mood at this point than on July 2^nd. In the east the Brusilov offensive was continuing (although waning). This, plus the entry of Rumania into the war on 28^th August (see future post) and an Allied breakout from Salonika led by Sarrail, strtetched German resources, particularly as the Austrian contributions fell away month on month. The slow but steady progress of the past month encouraged further attacks, and on 12^th September a major bombardment was launched along the line from Thiepval to Ginchy. This in preparation for an assault by the whole of Rawlinson’s 4^th army, now consisting of predominantly fresh troops shifted from other parts of the front. On 15^th at daybreak, the troops went over the top again in light mist. On the left Canadian and Scottish troops had success, carrying the villages of Courcelette and Martinpuich. New Zealanders in the next section moved on past High Wood towards Flers. Their action is famous for featuring the first appearance in combat of the tank. In small numbers, mechanically clumsy and unreliable, the Mark 1s nevertheless caused initial panic among the German infantry, who vacated their trenches in large numbers. To

the south partial success enabled progress from Ginchy towards Lesboeufs, but not link up with the French. The British Prime Minister’s son Raymond Asquith was a high profile casualty of the day – killed while leading a battalion of the Grenadier Guards from Ginchy village. Later in the day, German counter-attacks caused heavy British casualties, and the loss yet again of High Wood.

The entry of the tank into the war was dramatic, but strategically ineffective and not without controversy. Many wanted the Mark 1s to be held back until in larger numbers and with the improved Mark 2s, whereas Haig wanted every available weapon for his prized breakthrough. The Germans were now warned, and within a few days every German junior officer on the Western Front was issued with sketches and notes on how to counter them.

The attacks continued for the next week with small additional gains. The French continued to make steady progress to the SW of Peronne. By the 25^th, the British had taken the high ground beyond Morval, and with the capture of Combles on the right, now controlled most of the important high ground of the battlefield.

They paused to regroup, but appeared well placed to prepare their next move on the attritional road to Bapaume. Then the weather broke.
