Scipio Africanus

  Let us therefore compare Scipio with these three ancient great captains, by a threefold study and test—as general, as man, and as statesman. Any such comparison must be based on the conditions these men had to deal with, and on the skill with which they turned these conditions to their advantage.

  Alexander, and to a hardly less degree Caesar, enjoyed the immense asset of having autocratic power, complete control over the forces and resources available. Even Hannibal, if poorly supported, was immune from the petty interference with his operations against which Scipio, like Marlborough later, had to contend.

  Alexander’s victories were won over Asiatic hordes, whose lack of tactical order and method offset their numerical superiority, and as Napoleon demonstrated in his well-known comment on the Mamelukes, the defects of Asiatic troops increased in ratio with their numbers. No critic places Clive in the first rank of great captains, and but for the clear brilliance of his manoeuvres and the scale of his conquests Alexander would suffer a like discount. Cæsar, also, was hardly more than an able “ sepoy general ” until Ilerda and Pharsalus, and, as he himself is said to have remarked, he went “ to Spain to fight an army without a general, and thence to the East to fight a general without an army.” And even so, Cæsar found himself, owing to an unwise dispersion of force, twice forced to fight under the handicap of inferior strength. In the first, at Dyrrhacium, he suffered defeat, and though he atoned for it at Pharsalus, this single first-class victory is a slender base on which to build a claim to supreme generalship.

  But if we are to accept Napoleon’s dictum that “ in war it is not men but the man who counts,” the most significant fact is that both Alexander and Caesar had their path smoothed for them by the feebleness and ignorance of the commanders who opposed them. Only Hannibal, like Scipio, fought consistently against trained generals, and even as between these the advantage of conditions is on Hannibal’s side. For his three decisive victories—the Trebia, Trasimene, and Cannæ—were won over generals not only headstrong and rash, but foolishly disdainful of any tactics which savoured of craft rather than of honest bludgeon work. Hannibal knew this well—witness his remark to the troops who were to lie concealed for the flank attack at the Trebia, “ You have an enemy blind to such arts of war.” Flaminius and Varro were mental Beefeaters, and their names are instinctively bracketed in history with those of Tallard, Daun, Beaulieu, and MacMahon. Hannibal taught the Romans the art, as distinct from the mechanism, of war, and once they had profited by his instruction his successes were limited. Marcellus and Nero were capable of winning tricks off him, and if they could not take a rubber neither could Hannibal. But in surveying Scipio’s record, not only do we find his tactical success unchequered, but that his opponents from the outset were generals trained in the Barcine school, and all the evidence goes to show that Hannibal’s brothers, Hasdrubal and Mago, were no mean commanders. And the apex of Scipio’s career, Zama, is unique in history as the only battle where one acknowledged great captain has, on his own, defeated another decisively.

  Thus if conditions, and the extent to which they are not only met but turned to advantage, be the test, Scipio’s pre-eminence is clear.

  If the quality of a general’s art be the test, universal opinion concedes that Hannibal excelled Alexander and Cæsar. Alexander’s victories were rather triumphs of method, calculations working out with straightforward precision, but unmarked by any subtle variations and traps for the enemy. In Alexander, for all his greatness, still lingered traces of the Homeric hero, the glorification of the physical elements at the expense of the mental. It was this knighterrantry which led him to stake his life so often in the forefront of the battle, needlessly risking thereby the collapse of his plans and the lives of his army. To him might well be applied the rebuke made by Timotheus to Chares, when the former remarked: “ How greatly ashamed I was at the siege of Samos when a bolt fell near me ; I felt I was behaving more like an impetuous youth than like a general in command of so large a force.” This mistaken Bayardism, too, explains the absence of the subtler artistry in his battles—it is epitomised in his rejection of Parmenio’s proposal to attack Darius by night at Arbela, on the ground that he would not “ steal a victory.” Cæsar’s plans were assuredly more difficult to guess, but he did not “ mystify, mislead, and surprise ” to anything like the degree that Hannibal attained. So general is the recognition of Hannibal’s genius in this battle art that he is commonly termed the supreme tactician of history. Yet in ruse and strategem the record of Scipio’s battles is even richer. Recall the unfortified front, the timing of the direct assault, and the lagoon manoeuvre at Cartagena ; the double envelopment and reversal of adverse ground conditions at Bæcula. The change of hour and of dispositions, the refused centre, the double oblique, and the double convergent flank blows at Ilipa. As Colonel Denison notes in his ‘ History of Cavalry,’ Ilipa is “ generally considered to be the highest development of tactical skill in the history of Roman arms.” I would suggest that the student of war, if he considers it as a whole—from the mental opening moves to the physical end of the pursuit,—cannot but regard it as without a peer in all history. Continuing, observe the use of ground first to counter his enemy’s numbers and then to force him to fight separated battles, as well as the wide turning movement, against Andobales. Watch Scipio luring on his enemy into the ambush at Salæca; study his masterpiece in firing the Bagradas camps—the feint at Utica, the sounding of the evening call, the timing of and distinction between the two attacks, and the subtlety with which he gains possession of the main obstacle, the gates of the Carthaginian camp, without a struggle. Note, later, his novel use of his second and third lines as a mobile reserve for envelopment at the Great Plains, and the chameleon-like quickness with which he translates his art into the naval realm when he frustrates the attack on his fleet. Finally, at Zama, where he is confronted with an opponent proof against the more obvious if more brilliant stratagems, we see his transcendent psychological and tactical judgment in his more careful but subtly effective moves—the “lanes” in his formation, and the synchronised trumpet blast to counter the elephants; the deliberate “ calling off ” of the hastati ; the calculated change of dispositions by which he overlaps Hannibal’s third, and main, line ; the pause by which he gains time for the return of his cavalry, and their decisive blow in Hannibal’s rear.

  Is there such another collection of gems of military art in all history ? Can even Hannibal show such originality and variety of surprise ? Moreover, if Hannibal’s “ collection ” in open battle is somewhat less full than Scipio’s, in two other essentials it is bare. Even his devoted biographers admit that siegecraft, as with Frederick, was his weakness, and he has nothing to set off against Scipio’s storm of Cartagena, which, weighed by its difficulties, its calculated daring and skill, and its celerity, has no parallel ancient or modern.

  The other and more serious void in Hannibal’s record is his failure to complete and exploit his victories by pursuit. Nowhere does he show a strategic pursuit, and the lack of even a tactical pursuit after the Trebia and Cannæ is almost unaccountable. In contrast we have Scipio’s swift and relentless pursuit after Ilipa, and hardly less after the battle on the Great Plains—which alike for range and decisiveness are unapproached until Napoleon, if then. In ancient times Scipio has but one possible rival, Alexander, and in his case there was repeatedly an interregnum between the tactical and the strategic pursuit, which caused a distinct debit against his economy of force. For his turning aside after Issus a strategic argument can be made out, but for his delay after Granicus and Arbela there appears no cogent reason save possibly that of distance—the fact at least remains that his campaigns offer no pursuit so sustained and complete as that down the Bætis, or Guadalquiver. It may be suggested that Scipio did not always pursue as after the two battles cited. But an examination of his other battles show that pursuit was usually either rash or unnecessary—rash after Bæcula, where he had two fresh armies converging on him, and u
nnecessary after Zama, where there was no enemy left to be a danger.

  From tactics we pass to strategy, and here a preliminary demarcation and definition may simplify the task of forming a judgment. Strategy is too often considered to comprise merely military factors, to the overshadowing of the political and economic, with which it is interwoven. The fallacy has been responsible for incalculable damage to the fabric of warring nations. When such critics speak of strategy, they are thinking almost solely of logistical strategy—the combination in time, space, and force of the military pieces on the chessboard of war. Between logistical strategy and chess there is a distinct analogy. But on a higher plane, and with a far wider scope, is grand strategy, which has been defined as “ the transmission of power in all its forms in order to maintain policy.” “ While strategy is more particularly concerned with the movement of armed masses, grand strategy, including these movements, embraces the motive forces which lie behind them, material and psychological. ... The grand strategist we see is, consequently, also a politician and a diplomatist.” 10

  As a logistical strategist Napoleon is unrivalled in history—save possibly by the Mongol, Subutai, from what we can piece together of the scanty records of his campaigns. The ancients suffer, in common with the modern precursors of Napoleon, the handicap that the organisation of armies in their day did not permit of the manifold combinations that he effected, a handicap which persisted until the divisional system was born in the late eighteenth century, beginning with De Broglie. Previously we find detachments, or occasionally, as in Nero’s classic move to the Metaurus against Hasdrubal, a two-army combination, but the scope and variation of such combination were inevitably narrow until armies came to be organised in self-contained and independent strategic parts—the modern division or army corps—just in time for the genius of Napoleon to exploit these new possibilities. But within the inherent limitations of pre-Napoleonic times, Scipio develops a range of strategical moves which, it may be fairly claimed, is unequalled in the ancient world. The hawk-like swoop on Cartagena, so calculated that none of the three Carthaginian armies could succour their base in time. The hardly less bold and calculated blow at Hasdrubal Barca before either Hasdrubal Gisco or Mago could effect a junction—how closely the margin of time worked out we know from Polybius. Nor is there any doubt whether these strategic moves were deliberate, as in many ascribed to ancient commanders on supposition by military critics who view old theatres of war through modern spectacles. Polybius and Livy both tell us that these calculations were in Scipio’s mind. Again, the way in which Scipio stood guard over Hasdrubal Gisco while his detachment under Silanus moved and fell on Hanno and Mago before they had word of his approach. Swift as the march, as thorough was the defeat.

  Next, the master move leading to Ilipa, whereby his direction of advance cut Hasdrubal and Mago off from their line of communication with Gades, which in the event of their defeat meant that retreat to their fortified base was barred by the river Bætis (Guadalquiver). The upshot showed both the truth of his calculation and the proof of the fact—the result was the annihilation of the Carthaginian armies. This seems the first clear example in history of a blow against the strategic flank. Here is born the truth which Napoleon was to crystallise in his cardinal maxim that “ the important secret of war is to make oneself master of the communications.” Its initiation is sometimes claimed for Issus, but at best Alexander’s manoeuvre was on the battlefield, not in strategic approach, while the simple explanation is that the sea prevented a move on the other flank and that the bend in the river Pinarus dictated the direction of it.

  Admittedly Scipio’s strategic intention at Ilipa is a hypothesis, and not definitely stated in Livy or Polybius; but the established facts of the advance, and still more of its sequel, form a chain of indirect evidence that could not be firmer. Even Dodge, one of Scipio’s consistent detractors, emphasises this threat to the strategic flank.

  Before passing on to his African campaigns, we may note Scipio’s anticipation of, and trap for Hannibal at Locri. Then note how, on landing in Africa, his first care is to gain a secure base of operations, fulfilling the principle of security before he passes to the offensive. See him baulk the enemy’s superior concentration of strength by the “ Torres Vedras ” lines near Utica. Note the rapidity with which he strikes at Hasdrubal and Syphax at the Great Plain, before their new levies can be organised and consolidated, and how in the sequel he once more stands guard, this time over Carthage, while his detachment under Lælius and Masinissa knocks Syphax out of the war. Finally, there is his move up the Bagradas Valley by which he simultaneously compels Hannibal to follow, and facilitates his own junction with Masinissa’s reinforcement from Numidia. So complete is his mastery on the strategical chessboard that he even selects the battlefield most favourable to the qualities of his own tactical instrument Then, Zama decided, he pounces on Carthage before the citizens can rally from the moral shock.

  What, if any, mistakes can be set down on the debit side of his strategy ? A study of military commentaries shows that his critics advance but three—that Hasdrubal Barca and Mago in turn escaped from Spain, and that Scipio did not lay siege to Carthage immediately on landing in Africa. The obvious reply is to ask how many times did Darius, a far more vital personal factor, escape Alexander, why Cæsar let slip Pompey after Pharsalus, or Hannibal fail to move on Rome after Trasimene or Cannæ—there were far less adequate reasons. But apart from the extreme difficulty of catching an individual without an army, it is hoped that the earlier chapters may have disposed of these empty criticisms. Even after Bæcula, Scipio was still markedly inferior in strength to the Carthaginian forces in Spain, and further, Hasdrubal was only able to elude Scipio’s watch and cross the Pyrenees with so weak a contingent that he was forced to recruit in Gaul for two years before he could advance on Italy. Mago’s escape was still more an individualistic effort. As for the question of an immediate advance on Carthage, Scipio would have been an impetuous fool, not a general, if he had laid siege to so vast a fortified city as Carthage with the small original force that he carried into Africa. The clearest proof of his wisdom in first seeking a secure base of operations lies in the overwhelming enemy concentration from which he only escaped by his foresight in forming his “ Torres Vedras ” lines.

  In Alexander’s record even his modern biographers do not suggest any notable examples of logistical strategy, apart from certain swift marches such as that from Pelium on Thebes. There are no combinations or checks to enemy combination. His strength lies in his grand strategy, of which we shall speak later.

  With Hannibal, too, his logistical strategy is mainly a matter of direct marches and of admirable care to secure his communications, apart from the very disputable purpose of his move on the line of the Po which, in effect, separated the elder Scipio from Sempronius, his fellowconsul ; and secondly, his feint at Rome in the attempt to relieve the pressure on his allies at Capua, which, though clearly intended, was abortive. Against these must be set, first, the fact that the advantage of his hazardous march over the Alps was foiled of its purpose by the elder Scipio’s quicker return from the Rhone by the Riviera route; second, the fact that he failed to prevent the junction of Sempronius with Scipio on the Trebia. Later, there are, among other indisputable failures, the neglect to exploit Cannæ even by the seizure of Canusium, let alone a thrust at Rome ; the times his moves were parried by Fabius and Marcellus ; Nero’s brilliant deception by which Hannibal remained stationary and in the dark, while his brother was being crushed on the Metaurus. Finally, we see him outmanoeuvred by Scipio in the preliminary moves before Zama. Outstandingly great as a tactician, Hannibal is not impressive as a strategist ; less so, indeed, than several of Scipio’s forerunners among the Roman generals.

  Cæsar, in contrast, stands out more in logistical strategy than in tactics. But classic as are many of his moves in Gaul one has to remember that they were made against barbarians, not trained generals such as those with whom Scipi
o, Hannibal, Nero, and Marcellus had to contend. Against Pompey’s lieutenants in Spain he extricated himself with surpassing skill from a critical position, into which perhaps he should not have got. Then in Greece he threw away his superiority of force by dispersion, and suffered a severe defeat at Dyrrhacium, nearly disastrous as he confessed when he said: “ To-day the victory had been the enemy’s, had there been any one among them to gain it.” His retreat was a masterly feat, if we overlook the quality of his opponents, but later he failed in his attempt to prevent the junction of Pompey and Scipio Nasica, and had to fight at Pharsalus without his detachments against a concentrated force. That his tactics turned the balance does not affect the reflection on his strategy.

  If Scipio, then, may be given the palm for logistical strategy among the ancients, how does he compare with Napoleon ? We could adopt the historical argument that a man must be judged by the conditions and tools of his time, pointing out not only the indivisible organisation with which Scipio had to work, but that he was a pioneer where Napoleon had the experience of ages to build on. But we prefer rather to abandon this sound and normal test, which inevitably negatives true comparison, and admit frankly Napoleon’s supremacy in this sphere. The scales are amply balanced by Scipio’s superiority as a tactician. By wellnigh universal opinion Napoleon’s tactics were below his strategical level, and it is this compensating factor which has led military criticism to bracket Hannibal with Napoleon among the great captains—a factor which we suggest applies still more in Scipio’s favour compared with Napoleon.
