British air squadrons numbering sixty-eight machines on August 12, 1916, bombed airship sheds at Brussels and Namur, and railway sidings and stations at Mons, Namur, Busigny, and Courtrai. Of the British machines engaged in these attacks, all but two returned safely. In the evening of the same day the British forces attacked the third German position which extended from the east of Hardecourt to the Somme east of Buscourt. On this front of about four miles the British infantry carried the trench and works of the Germans to a depth of from 660 to 1,100 yards. To the northwest of Pozieres the British gained 300 to 400 yards on a front of a mile, and also captured trenches on the plateau northwest of Bazentin-le-Petit. The French continued to make appreciable gains south of the Somme, carrying portions of trenches and taking some prisoners. The new British front to the west of Pozieres was repeatedly attacked and bombarded by the Germans, and on August 15, 1916, they succeeded in recapturing trenches they had lost two days before. But they were unable to hold their gains for more than a day, when the British drove them out and consolidated the position. During the afternoon and evening of August 16, 1916, German and French to the north and south of the Somme engaged in heavy bombardments. At Verdun the German lines were forced back close to Fleury, the French taking enemy trenches and smashing a counterattack with their artillery. On the afternoon of August 17, 1916, there was hard fighting along the whole Somme front from Pozieres to the river. The British gained ground toward Ginchy and Guillemont and took over 200 prisoners, including some officers. During the night the Germans delivered repeated attacks against the positions the British had captured, but only in one instance did they succeed in winning back a little ground. On August 18, 1916, the British continued to add to their gains, advancing on a front of more than two miles for a distance of between 200 and 600 yards. As a result of these operations carried out along the British front from Thiepval to their right, south of Guillemont, a distance of eleven miles, was the gain of the ridge southeast of Thiepval commanding the village and northern slopes of the high ground north of Pozieres. The British also held the edge of High Wood and half a mile of captured German trenches to the west of the wood. Advances were also made to the outskirts of the village of Guillemont, where the British occupied the railroad station and quarry, both of some considerable military importance. As a result of these operations the British captured sixteen officers and 780 of other ranks.
