The loss of the plateaus north of Craonne continued to rankle in the mind of the German command, and repeated efforts were made to recover these precious positions. In the night of July 25, 1917, a ferocious attack was made on the French lines on a front of about two miles from La Bovelle Farm to a point east of Hurtebise. In the face of a murderous fire from the French artillery that wrought havoc in the advancing masses the Germans pressed on and succeeded in occupying portions of French first-line trenches south of Ailles. Repeated attacks made on Hurtebise Farm broke down under French artillery fire. Attacks on Mont Haut, following an intense bombardment that lasted all night long, failed to make any progress. North of Auberive the French carried out a successful operation during which they penetrated German trenches and continued their advance. In Flanders in the night of the 25th the town of Nieuport, which had been in ruins since the first year of the war, was bombarded by the Germans with guns of every caliber. The British guns replied with equal violence, so that for miles around the air vibrated day and night and the ground shook with tremors. East of Monchy the Germans resumed action, 400 attacking with flame throwers the line of British trenches that had already been smashed by artillery fire, and succeeded in occupying some posts of no great importance. In the Champagne the sorely tried French troops were allowed no respite by the Germans, who would not renounce their hope of regaining the important positions on the heights. In the night of July 26, 1917, no less than five attacks were made by the Germans in the vicinity of the height south and west of Moronvilliers, but all broke down under fire of the French artillery. East of Auberive, several groups of Germans led by an officer tried a surprise attack which led to close fighting and from which hardly one German soldier escaped unwounded. The ground around the French position was strewn with dead, including that of the officer who led the attack.
