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.

Nothing has ever been done by battalions of the Guards finer than the part they took in the battle of the Somme. It was not until the beginning of September that the Guards Division arrived in the Somme area, so it was not present at the first two phases of the battle. But in the attacks of September 15 and 25 the men covered themselves with glory; their discipline and coolness under fire were magnificent, and they captured lines which had up to then been considered impregnable. The final assault of Lesbœufs was one of the most successful operations of the war.

Not only were the staff arrangements admirable, but the co-operation between infantry and artillery proved in every way perfect. Against the unflinching attack of the Division nothing could stand; the mass of shells poured over by the German artillery, the hail of bullets from their machine-guns, and the rifle-fire of their infantry in the trenches, were all powerless to check it. The men were splendid: it made not a scrap of difference whether they had officers or not, whether they were with their own units or mixed up with other regiments. Nothing could stop them. When the 3rd Brigade went up, the battle had already been raging for over two months; and the Germans were then busily but vainly carrying out counter-attacks, in the hope of re-taking some of the ground that had been wrested from them. Consequently the two battalions sent forward came in for some very stiff fighting, especially the Welsh Guards, who went through some anxious moments owing to the advanced position they were occupying. They were fiercely attacked by large bodies of the enemy, but, with the help of one company of the 1st Battalion Grenadiers, managed to hold their own. Meanwhile the 4th Battalion Grenadiers――the other battalion sent up from the 3rd Brigade――held an uncomfortable position near the Quadrilateral, to the right and in rear of the Welsh Guards.
