[Sidenote: Fifth Army. March 22.] The reader is now in a position to form some conception of the situation of the Fifth Army upon the evening of March 21, and to understand the problems which confronted its commander. He was of opinion, and the opinion was shared by some at least of his corps commanders, that had he had four or five divisions of reserves within easy call, he could unquestionably have held the line. He had, however, to deal with the situation as it stood, and no man could have had a more difficult and responsible task. His own reserves were already practically engaged. On the other hand, both his air service and the reports of prisoners assured him that those of the enemy were numerous and near. His line had been deeply dented in four places: in the sector of the Sixteenth Division at Ronssoy, in that of the {114} Twenty-fourth Division at Maissemy, in that of the Fourteenth Division at Essigny, and in that of the Fifty-eighth Division opposite La Fère. These various points are, it will be observed, almost equidistant along the line, which tends to show that the German attack was conducted upon a plan which threw such forces upon limited areas that the result was almost a certainty, whatever troops might be holding them. It was the misfortune and not the fault of these gallant divisions that their thin ranks were in the very places which huge hordes of the enemy had marked in advance as their objectives.
