After 11 May, the Tenth Army began methodical local attacks, in which tactically important ground was attacked piecemeal, until another general attack could be made on Vimy Ridge. First-class French divisions had lost many experienced soldiers, which reduced them to mediocrity; the methods of Note 5779 had not been adopted consistently and became a greater problem when replacement troops with no experience, tried to continue the offensive.
The attempt in June to capture Vimy Ridge with another set-piece attack was a costly failure, despite the intervening period of local attacks on the flanks of XXXIII Corps and the capture of the Lorette Spur. French tactics were unchanged and the constant local attacks left no time for training. Revisions to the stipulations of Note 5779 in mid-June were of minor significance and an amendment of 18 June only referred to the importance of cavalry in mobile warfare. German defensive changes were easy to implement quickly and by June had made the French methods of May obsolete. For as long as the Germans were able to retain Souchez and Neuville, French attacks between them could not capture Vimy Ridge and the defences of the villages were too formidable to be overcome quickly. The original plan for a series of attacks might have been able to remove Souchez and Neuville as obstacles but the material constraints on the French in the spring of 1915, meant that the plan devised by Foch could not be implemented.
In September Foch wrote of the speed with which the Germans had moved reinforcements into the area from 9 to 18 May, dug new defensive lines and brought more heavy artillery into action, which from 18 May maintained barrages along all of the Tenth Army front. By 20 May the French artillery was dominated by the German artillery reinforcements, which severely inhibited the consolidation of captured ground and preparations for more attacks. Despite the change from attempts at continuous battle to methodical attacks, with pauses to reorganise and consolidate, the French took less ground, fewer prisoners and suffered more casualties. Foch concluded that a breakthrough was unlikely until the German armies in France had been depleted to a far greater extent; he advocated small step-by-step attacks, using methodical and economical methods. Fayolle wrote that the advocates of continuous battle were subject to a "grand illusion" and criticised Foch and d'Urbal for making unrealistic demands. André Laffargue, an artillery officer, was prompted to write Étude sur l'attaque dans le période actuelle de la guerre, an example of the trend to artillery-based tactics and infiltration by infantry.
