Ten minutes more, and they swung inside the great iron gates of the Sisters of Mercy. Never had Hilda felt the war so keenly as now. She had been dealing with it bit by bit. But here it was spread out beyond all dealing with. She had to face it without solutions.

There, in the Convent, known now as Military Hospital Number One, was row after row of Khaki men in bed. They had overflowed to the stone floor down the long corridors, hundreds of yards of length, and every foot close packed, like fish in a tin, with helpless outstretched men. The grey stones and the drab suits on the bundles of straw,—what a backwash from the tides of slaughter. If a man stood on his feet, he had to reach for a cane. There were no whole men there, except the busy stretcher-bearers bringing in new tenants for the crowded smelly place.

As quickly as they could unload their men, and stuff them into the corridor, Hilda and the doctor and Woffington sped back down the line, and up to the thronged dressing-stations. Wounded men were not their only charge, nor their gravest. They took in a soldier sobbing from the shock of the ceaseless shell fire. The moaning and wasp-like buzz of the flying metal, then the earth-shaking thud of its impact, and the roar of its high explosive, had played upon nerves not elastic enough to absorb the strain, till the man became a whimpering child. And they carried in a man shaking from ague, a big, fine fellow, trembling in every part, who could not lift a limb to walk. That which had been rugged enough for a lifetime of work became palsied after a few weeks of this king's sport. This undramatic slaughter was slower than the work of the guns, but it was as thorough. A man with colic was put into the car.

"I'm bad," he said. The pain kept griping him, so that he rode leaning down with his face pointed at the footboard.

Working as Hilda worked, with her two efficient friends and a well-equipped dressing-station, their own hospital only seven miles to the rear of them, she had been able to measure up to any situation that had been thrust at her. It was buckle to it, and work furiously, and clean up the mess, and then on to the next. But here was a wide-spread misery that overwhelmed her. Dr. McDonnell was as silent as the girl. He had a sensitiveness to suffering which twenty years of London practice had not dulled.

The day wore along, with spurt after spurt to the front, and then the slower drive back, when Woffington guided the car patiently and skilfully, so that the wounded men inside should not be shaken by the motion. They had a snack of luncheon with them, and ate it while they rode. Their little barrel of water, swinging between the wheels, had long ago gone to fevered men.

"First ambulance I've seen in twenty-four hours," said Captain Davies, as he came on them out of the dusk of Hoogar wood. The stern and unbending organization of the military had found it necessary to hold a hundred or more ambulances of the Royal Army Medical Corps in readiness all day in the market place of Ypres against a sudden evacuation. So there were simply no cars, but their one car, to speed out to the front and gather the wounded.

It was strange, in the evening light, to work out along the road between lines of poplar trees. Dim forms kept passing them—two by two, each couple with a stretcher and its burden. An old farm cart came jogging by, wrenching its body from side to side as it struck invisible hummocks and dipped into shell holes. It was loaded with outstretched forms of men, whose wounds were torn at by the jerking of the cart. In companies, fresh men, talking in whispers, were softly padding along the road on their way to the trenches, to relieve the staled fighters. The wide silence was only broken by the occasional sharp clatter and ping of some lonely sniper's rifle.

It was ten o'clock of the evening, and the ambulance had gone out one mile beyond the hamlet of Hoogar. The Doctor and Hilda alighted at the thick wood, which had been hotly contended for, through the seven days. It had been covered with shell fire as thoroughly as a fishing-net rakes a stream. They waited for Woffington to turn the car around. It is wise to leave a car headed in the direction of safety, when one is treading on disputed ground.
