German plans ruined.
And, indeed, this great attack of April 9, was the last general effort made by the German troops to carry out the programme of February—to capture Verdun and wipe out the French army which defended it. They had to give in. The French were on their guard now; they had artillery, munitions, and men. The defenders began to act as vigorously as the attackers; they took the offensive, recaptured the woods of La Caillette, and occupied the trenches before Le Mort Homme. The German plans were ruined. Some other scheme had to be thought out.
Verdun to be kept a battlefield.
A battle of attrition.
Instead of employing only eight divisions of excellent troops, as originally planned, the Germans had little by little cast into the fiery furnace thirty divisions. This enormous sacrifice could not be allowed to count for nothing. The German High Command therefore decided to assign a less pretentious object to the abortive enterprise. The Crown Prince's offensive had fallen flat; but, at all events, it might succeed in preventing a French offensive. For this reason it was necessary that Verdun should remain a sore spot, a continually menaced sector, where the French would be obliged to send a steady stream of men, material, and munitions. It was hinted then in all the German papers that the struggle at Verdun was a battle of attrition, which would wear down the strength of the French by slow degrees. There was no talk now of thunderstrokes; it was all "the siege of Verdun." This time they expressed the true purpose of the German General Staff; the struggle which followed the fight of April 9, now took the character of a battle of fixation, in which the Germans tried to hold their adversaries' strongest units at Verdun and prevent their being transferred elsewhere. This state of affairs lasted from mid-April to well into July, when the progress of the Somme offensive showed the Germans that their efforts had been unavailing.
Germans still formidable.
It is true that during this new phase of the battle the offensive vigor of the Germans and their procedure in attacking were still formidable.
Their artillery continued to perform prodigies. The medium-calibre pieces had now come into action, particularly the 150 mm. guns, with their amazing mobility of fire, which shelled the French first line, as well as their communications and batteries, with lightning speed. This storm of artillery continued night and day; it was the relentless, crushing continuity of the fire which exhausted the adversary and made the Battle of Verdun a hell on earth. There was one important difference, however: the infantry attacks now took place over restricted areas, which were rarely more than two kilometres in extent. The struggle was continual, but disconnected. Besides, it was rarely in progress on both sides of the river at once. Until the end of May the Germans did their worst on the left; then the French activities brought them back to the right side, and there they attacked with fury until mid-July.
A period of recuperation.
The end of April was a period of recuperation for the Germans. They were still suffering from the confusion caused by their set-backs of March, and especially of April 9. Only two attempts at an offensive were made—one on the Côte du Poivre (April 18) and one on the front south of Douaumont. Both were repulsed with great losses. The French, in turn, attacked on the 15th of April near Douaumont, on the 28th north of Le Mort Homme. It was not until May that the new German tactics were revealed: vigorous, but partial, attacks, directed now against one point, now against another.
