Battle of Ravenna (1512)

Battle of Ravenna (1512) serves in the text as a compact demonstration of both the peril of foreign military dependence and the possibilities of tactical adaptation. It appears within the discussion of auxiliary and national arms, where the fate of an army is inseparable from the political security of the prince who employs it: a victory won by another power may leave the supposed victor exposed, while a force trained to exploit an enemy’s defects can overturn an apparently superior system.

Context and Strategic Stakes

The immediate example concerns Pope Julius II’s use of auxiliaries in his attempt to gain Ferrara. He arranged with Ferdinand II of Aragon to receive horse and foot soldiers, thereby placing his enterprise in the hands of a foreign potentate. The danger of such troops was structural rather than accidental. If auxiliaries were defeated, the ruler who had called them in was undone; if they prevailed, he risked becoming their prisoner. Battle of Ravenna (1512) illustrates the first side of that dilemma, since the auxiliaries associated with Pope Julius II were defeated there before events outside their control rescued him from the full consequences of the decision.

The battle is also connected to a broader argument about the prevention of political danger. The text insists that rulers must confront disorders while they remain remote and manageable rather than waiting until they become obvious and incurable. The same logic governs military preparation: a prince should understand the relative strengths and weaknesses of different forces before committing his state to war, just as a prudent ruler should weaken dangerous powers before they acquire an opportunity to intervene. Foreign alliances are therefore treated as choices that alter the balance of power, not as neutral instruments that can be used without creating dependence.

Course and Tactical Illustration

At Battle of Ravenna (1512), the Spanish infantry confronted German companies whose discipline resembled that of the Swiss. The comparison matters because the text presents both Swiss and Spanish infantry as formidable but imperfect. Spanish troops were said to be vulnerable to cavalry, while Swiss troops could be forced to yield by resolute infantry engaging them at close quarters. The battle supplied an indication of how those defects might be exploited in practice.

Using their agility and bucklers, the Spanish infantry forced their way beneath the German pikes. Once below the reach of the pikes, they stood ready to close with the German companies, which were no longer in a position to defend themselves effectively. The Spanish appeared capable of driving the Germans into complete rout. Their success was checked only because cavalry charged them before they could finish the attack. The result therefore did not erase the tactical lesson: disciplined infantry, equipped and trained for close engagement, could penetrate a formation that seemed powerful at a distance.

The episode is presented cautiously. The text calls it an indication rather than a complete demonstration that the Swiss system could be broken by Spanish-style foot soldiers. Yet the incomplete outcome strengthens the argument’s practical character. The battle did not provide a simple tale of total victory; instead, it revealed a moment in which one military system’s vulnerability became visible, while the intervention of cavalry showed how quickly battlefield advantage could be reversed.

Auxiliary Arms and Political Consequences

The defeat at Ravenna placed Pope Julius II in the position that makes auxiliaries so dangerous. His foreign troops had been brought in to advance his objective at Ferrara, but their failure threatened to destroy the enterprise and leave him at the mercy of his enemies. The text describes his decision to rely on them as rash because he had thrown himself without reserve into the arms of a stranger. The political ruler and the military force were thus bound together in a relationship of dependence: the pope could not fully control the troops on which his immediate success rested.

Pope Julius II escaped the worst result through an unexpected intervention. After the auxiliaries were defeated at Ravenna, the Swiss suddenly descended and swept the victors out of the country. This reversal meant that Pope Julius II became neither a prisoner of his enemies, because they had been put to flight, nor a prisoner of his auxiliaries, because the victory had been won by other forces. The rescue did not make his original policy sound; it merely prevented its danger from becoming fatal.

The episode is set beside other examples that give the military warning a wider historical range. The Florentines, lacking soldiers of their own, brought ten thousand French men-at-arms to the siege of Pisa and thereby placed themselves in greater danger than before. The Emperor of Constantinople summoned ten thousand Turkish soldiers into Greece for protection; when the war ended, those troops refused to leave, beginning Greece’s subjection to the Infidel. Auxiliary forces are therefore distinguished from mercenaries by the immediacy of their danger: they are united and remain under their own officers, whereas mercenary companies, even after victory, require more time and opportunity before they can threaten the prince who hired them.

Lessons for National Arms

The military lesson drawn from Battle of Ravenna (1512) is that wise princes should prefer their own forces and regard victory won through foreign aid as no true victory. With mercenaries, the principal danger is their inertness and cowardice; with auxiliaries, it is their valour, because a powerful allied army can become an independent political force. Cesare Borgia is offered as a contrasting example. He entered Romagna with French auxiliary men-at-arms and used them to take Imola and Forli, but then judged them unreliable. He replaced them first with mercenary forces drawn from the Orsini and Vitelli, found those troops fickle, false, and treacherous, and finally turned to troops of his own raising.

Cesare Borgia’s reputation rose as his dependence on foreign and hired troops diminished. The text observes that he was never so well regarded as when everyone saw him to be the sole master of his forces. Hiero II of Syracuse followed an even more drastic course: after recognizing that mercenary soldiers were useless, he caused them all to be cut to pieces and thereafter made war with native troops alone. These comparisons transform the battlefield incident into a principle of statecraft. Military effectiveness is not measured only by immediate battlefield strength; it also depends on who commands the army, whose interests bind it, and whether victory strengthens or weakens the prince’s independence.

The final implication is directed toward national military reform. Spanish infantry and Swiss infantry each possessed serious strengths, but neither was invulnerable. A force trained on a different system could be designed to withstand cavalry and remain unafraid of infantry. The example at Ravenna suggests that such reform need not require entirely new forces; it could be achieved by changing the discipline of existing troops. In this sense, the battle is less a celebration of one army than evidence that military institutions can be redesigned around the weaknesses exposed by experience.

Significance in the Argument

Battle of Ravenna (1512) joins a chain of examples through which the text links war, political foresight, and the foundations of rule. The battle’s visible action is a clash between Spanish infantry and German companies, but its decisive significance lies in the conflict between borrowed power and power possessed by the prince himself. The Spanish penetration beneath the pikes demonstrates the value of tactical knowledge; the defeat of Pope Julius II’s auxiliaries demonstrates the political price of surrendering control over force; and the sudden Swiss intervention demonstrates how fortune can rescue a ruler from a decision that prudence should have prevented.

Its place in the argument is therefore deliberately double. Battle of Ravenna (1512) shows that an apparently formidable military formation may contain a precise and exploitable weakness, but it also warns that battlefield success cannot secure a state when the army belongs, in allegiance and command, to someone else. The event becomes a case study in the broader rule that a prince must build security on forces under his own authority, anticipate danger before it matures, and treat military organization as the primary foundation of political independence.
