Ludendorff admits the severity of that defeat.

“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.

“From April 10th onward the English attacked in the breach in great strength, but after all not in the grand manner; they extended their attack on both wings, especially to the southward as far as Bullecourt. On April 11th they gained Monchy, while we during the night before the 12th evacuated the Vimy heights. April 23d and 28th, and also May 3d, were again days of heavy, pitched battle. In between there was some bitter local fighting. The struggle continued, we delivered minor successful counter-attacks, and on the other hand lost ground slightly at various points.”

I remember many pictures of that fighting round Arras in the days that followed the first day. I remember the sinister beauty of the city itself, when there was a surging traffic of men and guns through its ruined streets in spite of long-range shells which came crashing into the houses. Our soldiers, in their steel hats and goatskin coats, looked like medieval men-at-arms. The Highlanders who crowded Arras had their pipe-bands there and they played in the Petite Place, and the skirl of the pipes shattered against the gables of old houses. There were tunnels beneath Arras through which our men advanced to the German lines, and I went along them when one line of men was going into battle and another was coming back, wounded, some of them blind, bloody, vomiting with the fumes of gas in their lungs—their steel hats clinking as they groped past one another. In vaults each side of these passages men played cards on barrels, to the light of candles stuck in bottles, or slept until their turn to fight, with gas-masks for their pillows. Outside the Citadel of Arras, built by Vauban under Louis XIV, there were long queues of wounded men taking their turn to the surgeons who were working in a deep crypt with a high-vaulted roof. One day there were three thousand of them, silent, patient, muddy, blood-stained. Blind boys or men with smashed faces swathed in bloody rags groped forward to the dark passage leading to the vault, led by comrades. On the grass outside lay men with leg wounds and stomach wounds. The way past the station to the Arras-Cambrai road was a death-trap for our transport and I saw the bodies of horses and men horribly mangled there. Dead horses were thick on each side of an avenue of trees on the southern side of the city, lying in their blood and bowels. The traffic policeman on “point duty” on the Arras-Cambrai road had an impassive face under his steel helmet, as though in Piccadilly Circus; only turned his head a little at the scream of a shell which plunged through the gable of a corner house above him. There was a Pioneer battalion along the road out to Observatory Ridge, which was a German target. They were mending the road beyond the last trench, through which our men had smashed their way. They were busy with bricks and shovels, only stopping to stare at shells plowing holes in the fields on each side of them. When I came back one morning a number of them lay covered with blankets, as though asleep. They were dead, but their comrades worked on grimly, with no joy of labor in their sweat.

Monchy Hill was the key position, high above the valley of the Scarpe. I saw it first when there was a white village there, hardly touched by fire, and afterward when there was no village. I was in the village below Observatory Ridge on the morning of April 11th when cavalry was massed on that ground, waiting for orders to go into action. The headquarters of the cavalry division was in a ditch covered by planks, and the cavalry generals and their staffs sat huddled together with maps over their knees. “I am afraid the general is busy for the moment,” said a young staff-officer on top of the ditch. He looked about the fields and said, “It's very unhealthy here.” I agreed with him. The bodies of many young soldiers lay about. Five-point-nines (5.9's) were coming over in a haphazard way. It was no ground for cavalry. But some squadrons of the 10th Hussars, Essex Yeomanry, and the Blues were ordered to take Monchy, and rode up the hill in a flurry of snow and were seen by German gunners and slashed by shrapnel. Most of their horses were killed in the village or outside it, and the men suffered many casualties, including their general—Bulkely Johnson—whose body I saw carried back on a stretcher to the ruin of Thilloy, where crumps were bursting. It is an astonishing thing that two withered old French women stayed in the village all through the fighting. When our troops rode in these women came running forward, frightened and crying “Camarades!” as though in fear of the enemy. When our men surrounded them they were full of joy and held up their scraggy old faces to be kissed by these troopers. Afterward Monchy was filled with a fury of shell-fire and the troopers crawled out from the ruins, leaving the village on the hill to be attacked and captured again by our infantry of the 15th and 37th Divisions, who were also badly hammered.

Heroic folly! The cavalry in reserve below Observatory Hill stood to their horses, staring up at a German airplane which came overhead, careless of our “Archies.” The eye of the German pilot must have widened at the sight of that mass of men and horses. He carried back glad tidings to the guns.

One of the cavalry officers spoke to me.

“You look ill.”

“No, I'm all right. Only cold.”
