Suddenly Mooska's horse took the bit in his teeth and bolted back out of the ranks, and bit and spur were of no avail to make him turn and advance again. The panic-terror had come; he was fighting for his life, for now the swamp was giving way and he was sinking at every footstep. Behind them there was being enacted a scene that baffles description as the treacherous quagmire began to claim its toll. The cries and shrieks of men and beasts as they were engulfed added horror to the dreadful situation.

Presently, realizing what was amiss, Mooska dismounted to take the weight off his floundering horse. A discarded plank that he came across enabled him to struggle on by pushing it in front of them, and yard by yard man and beast fought their way to firmer ground, not daring to stop to rest for a moment lest the delay should be fatal. By this time the Cossack was almost exhausted, yet he floundered on with the desperation of despair, for within view was higher ground which he believed to be the edge of the marsh. Could he hold out till then? His panting steed, dripping with sweat and covered with mud, was—like himself—nearly spent, but side by side they stumbled on, with eyes fixed in that goal which was their only hope of preservation. At last the earth felt firmer; they were no longer sinking ankle-deep at every step. Then the Cossack, taxed beyond his strength, fell forward on his face, and everything became a blank to him.

III—THE YOUNG COSSACK IN THE MARSHES

That bit of dry land, as it happened, was the commencement of a low ridge of hard ground on the border of the morass. The exhausted horse stood beside his master, with legs extended and heaving flanks, turning his nose to the wind as he panted for breath. The treacherous marshes stretched away for miles on every side, and the panic-terror ran through the animal like an electric shock. Behind him in the bogs the tragedy wore on to its climax. Maddened horses broke away, men were knocked down and rendered helpless, and animals and humans were sucked down to a dreadful death. The columns in the rear had hardly left the firm road before the darkness of night hid the inferno in front, and only a few stragglers escaped to tell the tale of what befell that day. When the sun was once more high in the heavens, the survivors marched back from that dreadful place with leaden feet, shoulders huddled forward, and red-rimmed eyes; they were thinking of the fearful fate of their comrades.

As they trudged along the dusty road, the weary men stepping slowly under the weight of their packs, they saw a little Cossack horse a short distance from the highway, with drooping head and tired eyes, standing under the shade of an overhanging tree beside a motionless bundle covered with caked mud. The horse whinnied as they drew near, and lifted his odd-shaped burden with his teeth. For a few yards he struggled on with it; then he laid it down from sheer exhaustion.

"It looks like a man; see if he lives," ordered an officer. A sergeant came forward and found that the helpless Cossack was still breathing. How long he had lain there he never knew, for his faithful horse had carried him by his belt little by little, yard by yard, from the place where he had fallen—five weary versts away, they told him—till he reached the shelter of those trees by the roadside. He had never left his master save for a short time to crop the herbage or drink from a pool during that long night and the day that followed. And now, when he could do no more, help had come.

When Mooska Zarden's senses returned to him he seemed to remember lying in the moonlight during that long night, with nothing but the stars above him, and feeling the soft nose of the faithful animal touch his hand; and he would feebly move it to show that he was alive. Then his belt would tighten and he would be dragged on gently for a few yards and laid down again, still only semi-conscious. Now the soldiers were giving him restoratives, but he felt little except the throbbing of his head. He opened his eyes feebly at last, but could not speak or think. When he was placed on a stretcher the horse broke away from the man who was leading him and took his place beside the bearers, every now and then putting his nose against the shoulder of the prostrate figure.

"Let him be till we fall in with a Cossack regiment or some stragglers of his own corps," said the colonel. "He saved the trooper's life."
