He had cooled his parched throat with a long draught of somewhat muddy water, but he had eaten only half of the armful of hay when again the bugles sounded and "Mars" Clayton appeared. Tightening the girths, until they almost cut into Pasha's tender skin, he jumped into the saddle and rode off to where a lot of big black horses were being reined into line. In front of this line Pasha was wheeled. He heard the bugles sound once more, heard his rider shout something to the men behind, felt the wicked little knives in his sides, and then, in spite of aching legs, was forced into a sharp gallop. Although he knew it not, Pasha had joined the Black Horse Cavalry.
The months that followed were to Pasha one long, ugly dream. Not that he minded the hard riding by day and night. In time he became used to all that. He could even endure the irregular feeding, the sleeping in the open during all kinds of weather, and the lack of proper grooming. But the vicious jerks on the torture-provoking cavalry bit, the flat sabre blows on the flank which he not infrequently got from his ill-tempered master, and, above all, the cruel digs of the spur-wheels—these things he could not understand. Such treatment he was sure he did not merit. "Mars" Clayton he came to hate more and more. Some day, Pasha told himself, he would take vengeance with teeth and heels, even if he died for it.
In the meantime he had learned the cavalry drill. He came to know the meaning of each varying bugle-call, from reveille, when one began to paw and stamp for breakfast, to mournful taps, when lights went out, and the tents became dark and silent. Also, one learned to slow from a gallop into a walk; when to wheel to the right or to the left, and when to start on the jump as the first notes of a charge were sounded. It was better to learn the bugle-calls, he found, than to wait for a jerk on the bits or a prod from the spurs.
No more was he terror-stricken, as he had been on his first day in the cavalry, at hearing behind him the thunder of many hoofs. Having once become used to the noise, he was even thrilled by the swinging metre of it. A kind of wild harmony was in it, something which made one forget everything else. At such times Pasha longed to break into his long, wind-splitting lope, but he learned that he must leave the others no more than a pace or two behind, although he could have easily outdistanced them all.
Also, Pasha learned to stand under fire. No more did he dance at the crack of carbines or the zipp-zipp of bullets. He could even hold his ground when shells went screaming over him, although this was hardest of all to bear. One could not see them, but their sound, like that of great birds in flight, was something to try one's nerves. Pasha strained his ears to catch the note of each shell that came whizzing overhead, and, as it passed, looked inquiringly over his shoulder as if to ask, "Now what on earth was that?"
But all this experience could not prepare him for the happenings of that never-to-be-forgotten day in June. There had been a period full of hard riding and ending with a long halt. For several days hay and oats were brought with some regularity. Pasha was even provided with an apology for a stall. It was made by leaning two rails against a fence. Some hay was thrown between the rails. This was a sorry substitute for the roomy box-stall, filled with clean straw, which Pasha always had at Gray Oaks, but it was as good as any provided for the Black Horse Cavalry.
And how many, many horses there were! As far as Pasha could see in either direction the line extended. Never before had he seen so many horses at one time. And men! The fields and woods were full of them; some in brown butternut, some in homespun gray, and many in clothes having no uniformity of color at all. "Mars" Clayton was dressed better than most, for on his butternut coat were shiny shoulder-straps, and it was closed with shiny buttons. Pasha took little pride in this. He knew his master for a cruel and heartless rider, and for nothing more.
One day there was a great parade, when Pasha was carefully groomed for the first time in months. There were bands playing and flags flying. Pasha, forgetful of his ill-treatment and prancing proudly at the head of a squadron of coal-black horses, passed in review before a big, bearded man wearing a slouch hat fantastically decorated with long plumes and sitting a great black horse in the midst of a little knot of officers.
Early the next morning Pasha was awakened by the distant growl of heavy guns. By daylight he was on the move, thousands of other horses with him. Nearer and nearer they rode to the place where the guns were growling. Sometimes they were on roads, sometimes they crossed fields, and again they plunged into the woods where the low branches struck one's eyes and scratched one's flanks. At last they broke clear of the trees to come suddenly upon such a scene as Pasha had never before witnessed.
Far across the open field he could see troop on troop of horses coming toward him. They seemed to be pouring over the crest of a low hill, as if driven onward by some unseen force behind. Instantly Pasha heard, rising from the throats of thousands of riders, on either side and behind him, that fierce, wild yell which he had come to know meant the approach of trouble. High and shrill and menacing it rang as it was taken up and repeated by those in the rear. Next the bugles began to sound, and in quick obedience the horses formed in line just on the edge of the woods, a line which stretched and stretched on either flank until one could hardly see where it ended.
