All were equally alert, untiring, vigilant, indomitable. But Alexander was sometimes carried beyond the bounds of reason by his defiance of danger. Cæsar’s intellectual powers were more pronounced in action than his physical. Hannibal was always, in brain and heart, the true captain; remembering his own necessity to his cause, but remembering also the necessity to his cause of victory.

All maintained discipline at an equal standard. All fired their soldiers to the utmost pitch in battle, all encouraged them to bear privation in the field, and bore it with them. All equally won their soldiers’ hearts. All obtained this control over men by scrupulous care of their army’s welfare, courage equal to any test, readiness to participate in the heat and labor of the day, personal magnetism, justice in rewards and punishments, friendliness in personal intercourse, and power of convincing men. In what they said, Alexander and Hannibal spoke plain truths plainly. Cæsar was a finished orator. But Cæsar and Alexander were so placed as readily to win the hearts of their soldiers. That Hannibal did so, and kept the fealty of his motley crowd of many nationalities throughout thirteen long years of disaster, is one of the phenomenal facts of history.

Personal indifference or cruelty can not be charged to the score of any one of them. Each gave frequent proof that he possessed abundant human kindness. But Alexander was at times guilty of acts of brutality and injustice. To Hannibal’s score can be put nothing of the kind. Cæsar by no means lacked the gentler virtues. Some claim for him sweetness equal to his genius. But he exhibited in the Gallic War a singularly blunted conscience. Peoples were mere stepping-stones to his progress. Judging Cæsar solely by his Commentaries, there goes hand in hand with a chivalrous sense a callousness which is unapproached. He could be liberal in his personal dealings, and unfeeling in his public acts; magnanimous and ruthless.

Alexander and Hannibal were ambitious, but nobly so, and generous withal. Cæsar’s ambition more nearly approached egotism. It was not honor, but power, he sought. Not that he loved Rome less, but Cæsar more. He was satisfied with nothing falling short of absolute control. But Cæsar was not miserly. Gold was only counted as it could contribute to his success. He was as lavish in the use of money as he was careless of his methods of getting it. So far as native generosity was concerned, Cæsar had, perhaps, as much as either of the others.

All three were keen in state-craft. But Alexander was frankly above-board in his dealings. Hannibal kept his own counsel, making no promises, nor giving his confidence to any. Cæsar was able, but underhanded whenever it suited his purpose. He could be more cunning in negotiation than even Hannibal, because less scrupulous. He could exert his powers to bring the wavering or inimical to his side in a most faultless manner.

In accomplishing vast results with meagre means, Alexander apparently did more than either Hannibal or Cæsar in contending with savage or semi-civilized tribes. The difference in numbers between Alexander and the Oriental armies he met was greater, as a rule, than anything Cæsar had to encounter. Yet on one or two occasions, as at the River Axona and at Alesia, Cæsar was faced by overwhelming odds. Hannibal was the only one of the three who contended against forces better armed, better equipped, more intelligent, and ably led. There is no denying him the palm in this. Of all the generals the world has ever seen, Hannibal fought against the greatest odds. Alexander never encountered armies which were such in the sense the Macedonian army was. Cæsar fought both against barbarians and against Romans. Not equal, perhaps, in his contests with the former, to Alexander, he was never taxed with such opponents as was Hannibal. It is difficult to say that either of the three accomplished more with slender means than the other. To reduce them to the level of statistics savors of the absurd.

Each devoted scrupulous care to the welfare of his troops; to feeding, clothing, and arming them; to properly resting them in winter quarters, or after great exertions, and to watching their health.

Fortune, that fickle jade, was splendid Alexander’s constant companion from birth till death. She forsook patient Hannibal after Cannæ, and thenceforward persistently frowned upon him. She occasionally left brilliant Cæsar,—but it was for a bare moment,—she always returned to save him from his follies, and was, on the whole, marvellously constant to him. Cæsar had to work for his results harder than Alexander, but in no sense like overtaxed, indomitable Hannibal. Alexander will always remain essentially the captain of fortune; Hannibal essentially the captain of misfortune; Cæsar holds a middle place. But had not Fortune on many occasions rushed to the rescue Cæsar would never have lived to be Cæsar.

In common, these three great men obtained their results by their organized system of war, that is, war founded on a sound theory, properly worked out. To-day war has been reduced to a science which all may study. Alexander knew no such science, nor Hannibal, nor indeed Cæsar. What was, even so late as Cæsar’s day, known as the art of war, covered merely the discipline of the troops, camp and permanent fortifications, sieges according to the then existing means, and the tactics of drill and battle. What has come down to this generation, as a science, is a collection of the deeper lessons of these very men and a few others, reduced during the past century by able pens to a form which is comprehensible. Even Napoleon was annoyed at Jomini’s early publications, lest the world and his opponents should learn his methods of making war. We must remember that these captains of ancient times were great primarily, because they created what Napoleon calls methodical war. It was many centuries before any one understood the secret of their success. But Gustavus, Frederick, and Napoleon guessed the secret and wrought according to it; and they made war in a day when busy brain-tissue could analyze their great deeds for the benefit of posterity.

Whatever their terms for designating their operations, the great captains of antiquity always had a safe and suitable base; always secured their rear, flanks, and communications; always sought the most important points as objective, generally the enemy himself; and divided their forces only for good reasons, at the proper moment again to bring them together. We find in their history few infractions of the present maxims of war, and only such as a genius is justified in making, because he feels his ability to dictate to circumstances.
