When O'Reilly and Branch enlisted in the Army of the Orient they were assigned to the command of Colonel Miguel Lopez, and it was under his leadership that they made their first acquaintance with the peculiar methods of Cuban warfare.

Active service for the two Americans began at once; scarcely a week had passed before Leslie Branch gained his opportunity of tasting the "salt of life" in its full flavor, for the young Matanzas colonel was one of the few Cuban commanders who really enjoyed a fight.

There had been, at first, some doubt of Branch's fitness to take the field at all—he had suffered a severe hemorrhage shortly after his arrival at Cubitas—and it was only after a hysterical demonstration on his part that he had been accepted as a soldier. He simply would not be left behind. At first the Cubans regarded him with mingled contempt and pity, for certainly no less promising volunteer had ever taken service with them. Nevertheless, he would doubtless have made many friends among them had he not begun his service by refusing to abide by discipline of any sort and by scorning all instruction in the use of arms, declaring this to be, in his case, a silly waste of effort. Such an attitude very naturally aroused resentment among the other men; it was not long before they began to grumble at the liberty allowed this headstrong weakling. But upon the occasion of the very first fight this ill-will disappeared as if by magic, for, although Branch deliberately disobeyed orders, he nevertheless displayed such amazing audacity in the face of the enemy, such a theatrical contempt for bullets, as to stupefy every one. Moreover, he lived up to his reputation; he continued to be insanely daring, varying his exploits to correspond with his moods, with the result that he attained a popularity which was unique, nay, sensational.

His conduct in the face of this general admiration was no less unexpected than his behavior under fire: Branch gruffly refused to accept any tribute whatever; he snarled, he fairly barked at those of his comrades who tried to express their appreciation of his conduct—a demeanor which of course awakened even greater admiration among the Cubans. He was uniformly surly and sour; he sneered, he scoffed, he found fault. He had the tongue of a common scold, and he used it with malevolent abandon.

It was fortunate indeed that he knew no Spanish and that most of his companions were equally ignorant of English, for mere admiration, even of the fervent Latin quality, would scarcely have been proof against his spleen. As it was, his camp-mates endured his vituperations blandly, putting him down as a pleasing eccentric in whom there blazed a curious but inspiring spirit of patriotism.

O'Reilly alone understood the reason for the fellow's morbid irritability, his suicidal recklessness; but when he privately remonstrated he was gruffly told to mind his own business. Branch flatly refused to modify his conduct; he seemed really bent upon cheating the disease that made his life a misery.

But, as usual, Fate was perverse; she refused to humor the sick man's hope. When, after blindly inviting death, Leslie had emerged from several engagements unscathed, his surprise—and perhaps a natural relief at finding himself whole—became tinged with a certain apprehension lest he survive those deliberately courted dangers, only to succumb to the ills and privations of camp life. Cuban equipment was of the scantiest. Cuban dews are heavy; Cuban nights are cool—these were perils indeed for a weak-lunged invalid. Branch began to fret. Rain filled him with more terror than fixed bayonets, a chill caused him keener consternation than did a thousand Spaniards; he began to have agonizing visions of himself lying in some leaky hovel of a hospital. It was typical of his peculiar irritability that he held O'Reilly in some way responsible, and vented upon him his bitterness of spirit.

The fellow's tongue grew ever sharper; his society became intolerable, his gloom oppressive and irresistibly contagious. When, after several weeks of campaigning, the column went into camp for a short rest, O'Reilly decided that he would try to throw off the burden of Leslie's overwhelming dejection, and, if possible, shift a portion of it upon the shoulders of Captain Judson.

On the day after their arrival O'Reilly and the big artilleryman took advantage of a pleasant stream to bathe and wash their clothes; then, while they lay in their hammocks, enjoying the luxury of a tattered oil-cloth shelter and waiting for the sun to dry their garments, O'Reilly spoke what was in his mind.

"I'm getting about fed up on Leslie," he declared. "He's the world's champion crepe-hanger, and he's painted the whole world such a deep, despondent blue that I'm completely dismal. You've got to take him off my hands."
