Chapter 13
The Danger of Borrowed Armies—And Why You Must Build Your Own
CONCERNING AUXILIARIES, MIXED SOLDIERY, AND ONE’S OWN Auxiliaries, which are the other useless arm, are employed when a prince is called in with his forces to aid and defend, as was done by Pope Julius in the most recent times; for he, having, in the enterprise against Ferrara, had poor proof of his mercenaries, turned to auxiliaries, and stipulated with Ferdinand, King of Spain,[1] for his assistance with men and arms. These arms may be useful and good in themselves, but for him who calls them in they are always disadvantageous; for losing, one is undone, and winning, one is…

Key Quotes & Analysis
"In conclusion, in mercenaries dastardy is most dangerous; in auxiliaries, valour. The wise prince, therefore, has always avoided these arms and turned to his own; and has been willing rather to lose with them than to conquer with the others, not deeming that a real victory which is gained with the arms of others."
Context: Mercenaries vs auxiliaries
Cowardly mercenaries lose wars; valiant auxiliaries win them for someone else. Own arms are the only victory that counts.
In Today's Words:
Auxiliaries are worse than mercenaries because they arrive as someone else's army. Florence called French troops; the Pope relied on Spain. Both learned that a stronger ally who wins for you can own the outcome afterward. Borrowed victory is often borrowed sovereignty, even when the battle goes your way.
"he was never esteemed more highly than when every one saw that he was complete master of his own forces."
Context: Cesare Borgia's progression to native arms
Reputation peaks when observers see you command soldiers loyal to you alone.
In Today's Words:
Machiavelli says losing with your own troops is less shameful than winning with borrowed ones. That is a hard lesson for leaders who want a quick fix. If you cannot defend the result with forces loyal to you, you have not really secured the state. You have rented a temporary advantage.
"I conclude, therefore, that no principality is secure without having its own forces; on the contrary, it is entirely dependent on good fortune, not having the valour which in adversity would defend it. And it has always been the opinion and judgment of wise men that nothing can be so uncertain or unstable as fame or power not founded on its own strength."
Context: Closing conclusion
Machiavelli's final military verdict: borrowed power is unstable because it is not yours in crisis.
In Today's Words:
Building your own army in modern terms means developing people, systems, and leverage you control directly. In a campaign, company, or movement, that looks like loyal field staff, owned data, and operators who answer to you rather than to the vendor, donor, or parent organization that could pull them away tomorrow.
"the arms of others either fall from your back, or they weigh you down, or they bind you fast."
Context: David rejecting Saul's armor
Borrowed tools do not fit your fight. They fail, burden you, or trap you.
In Today's Words:
Auxiliaries are worse than mercenaries because they arrive as someone else's army. Florence called French troops; the Pope relied on Spain. Both learned that a stronger ally who wins for you can own the outcome afterward. Borrowed victory is often borrowed sovereignty, even when the battle goes your way.

Discussion Questions
This is not a test. Five prompts guide you through the chapter, from how it opens to how it closes, so you notice context and rhythm rather than facts to memorize. Sit with each question in your own words. When you see "One way to read it," treat it as a starting point, not the only answer.
- 1
How do auxiliary arms differ from mercenaries, and why are they even more dangerous?
analysis • mediumOne way to read it
Auxiliaries are another ruler's troops called in to help you. They are united and obedient to their own master. If you lose, you are undone; if you win, you become their captive. Valorous auxiliaries are more dangerous than cowardly mercenaries because victory itself can cost you independence.
- 2
What happened to Florence when it called in French auxiliaries, and to Greece when the Emperor sent Turkish troops?
analysis • mediumOne way to read it
Florence sent ten thousand Frenchmen to take Pisa and ran greater danger than in any other crisis. The Emperor of Constantinople invited Turks into Greece; when the war ended, they would not leave, beginning Greek servitude to infidels. Invited allies often stay as masters.

Why does Machiavelli say losing with your own troops is less shameful than winning with borrowed ones?
analysis • deepOne way to read it
A real victory requires power you control afterward. Borgia's reputation rose highest when everyone saw he commanded his own soldiers. Fame or security not founded on your own strength remains uncertain and can be revoked by whoever lent you the force.
- 4
When have you seen an organization win a short-term fight by inviting in a stronger ally who then owned the outcome?
application • mediumOne way to read it
Think of startups accepting acquirers for rescue capital, campaigns rescued by a national party that then dictated staffing, or firms that won a market battle only to become dependent on a vendor or investor who supplied the decisive resource.
- 5
What would building your own army look like in a modern campaign or company, not on a battlefield?
application • deepOne way to read it
It means loyal staff, owned data, internal fundraising, and operational capacity that survives if every contractor and patron withdrew tomorrow. Machiavelli's lesson is structural: convert borrowed force into citizens and dependents who answer to you alone.
