“The battle near Arras on April 9th formed a bad beginning to the capital fighting during this year.

“April 10th and the succeeding days were critical days. A breach twelve thousand to fifteen thousand yards wide and as much as six thousand yards and more in depth is not a thing to be mended without more ado. It takes a good deal to repair the inordinate wastage of men and guns as well as munitions that results from such a breach. It was the business of the Supreme Command to provide reserves on a large scale. But in view of the troops available, and of the war situation, it was simply not possible to hold a second division in readiness behind each division that might, perhaps, be about to drop out. A day like April 9th upset all calculations. It was a matter of days before a new front could be formed and consolidated. Even after the troops were ultimately in line the issue of the crisis depended, as always in such cases, very materially upon whether the enemy followed up his initial success with a fresh attack and by fresh successes made it difficult for us to create a firm front. In view of the weakening of the line that inevitably resulted, such successes were only too easy to achieve.
