The long and severe struggle, which was the second phase, began on July 18 and culminated on September 15 with the fall of Ginchy, after Pozières, Delville Wood, Guillemont, Falfemont Farm, and Leuze Wood had been taken in succession. But although the main ridge from Delville Wood to the road above Mouquet Farm was secured, Morval on the right and Thiepval on the left remained in German hands. In the third phase Flers, High Wood, Martinpuich, Courcelette, and the Quadrilateral came into our hands one after another, and on September 25 Morval, Lesbœufs, and Gueudecourt were secured by the British Army, while the French took Combles. During October Thiepval was taken, and also Eaucourt l’Abbaye and Le Sars, while in November, as the outcome of an advance on both sides of the Ancre, we captured St. Pierre Divion, Beaucourt, and Beaumont-Hamel. Thus all our principal objects were achieved, in spite of the fact that the Germans were able to mass more than half their army upon this part of their front. The British Army took 38,000 prisoners, including over 800 officers; also 29 heavy guns, 96 field-guns and field-howitzers, 136 trench mortars, and 514 machine-guns. The battle was marked by the sudden appearance of the Tanks. So well had their secret been kept that until they came upon the battlefield the Germans had no idea of their existence. “The Machine-gun Corps, Heavy Section” was the official title of these heavy armoured cars which could move anywhere, over trenches and through wire entanglements, pushing down walls and even houses; they contained a garrison of six men with machine-guns and 6-pdr. guns. So many legends had grown up of their supernatural powers that their actual début caused a certain disappointment. But although in some parts of the battlefield they failed us, some of them did wonders, and many of the strongholds in the German line could never have been taken without their help. The net result of the battle was a brilliant victory for the British Army, for not only was a large tract of ground captured from the enemy, but the three objects which we had set out to gain were fully attained. Verdun was relieved of pressure, the main portion of the German Army was detained on the Western front, and a crippling blow was struck at the enemy forces. It was clearly shown that, on anything like equal terms, the British could drive back the German Army, sheltered even by the strongest entrenchments. As the area and duration of modern battles are immense, a long time naturally elapses before their effects are felt by the losing side. Formerly battles lasted only a few days, and their results were seen immediately in the retirement of the beaten army. After the battle of the Somme, however, nothing happened at first, and it was not until six months later that the Germans found that their positions had become untenable, and a general retirement was advisable.
