In 1519 Hernán Cortés landed in eastern Mexico with a small army and a plan to conquer the Aztec Empire.
Before any of that, he had a different problem. He had to conquer his own men.1
Specifically, a small but vocal group loyal to Diego de Velázquez, the governor of Cuba — who had sent Cortés on nothing more than a scouting mission and who wanted the conquest of Mexico for himself.1
Velázquez's supporters caused trouble at every step, conspiring constantly.
And they had a grievance with a defensible surface. The Spanish were supposed to collect gold for the king of Spain. Cortés had been letting his soldiers barter for it and then using that gold to buy food.
This practice, the Velázquez men argued, must end.1
That is a perfectly reasonable position. It is also a moderate one, and moderate positions are, as Greene puts it elsewhere in the chapter, hard to attack because there isn't much there to aim at.
Cortés appeared to concede — and then did something slightly more than concede.
Appearing to concede, Cortés suggested the Velázquez men appoint a treasurer.1
They quickly named one of their own. And with their help, this man began to collect everyone's gold.1
Read what has just happened. Cortés did not lose an argument about policy. He converted a criticism into an administration — and put the critics in charge of it, with their name on it.
The consequence was entirely predictable and Cortés did nothing to soften it.
This policy, naturally, proved extremely unpopular with the soldiers, who were braving enormous dangers for little benefit. They complained bitterly1
And here is the whole technique in one clause:
but Cortés just pointed to the men who had insisted on this policy in the name of the governor of Cuba. He personally, of course, had never been in favor of it.1
He did not defend the policy. He did not attack it. He pointed.
Soon the Velázquez men were universally hated, and Cortés at the urgent request of the other soldiers, gladly rescinded the policy. From then on, the conspirators could get nowhere with the men. They were exposed and despised.1
Note the exit as well as the entry. Rescinding the policy at the soldiers' urgent request is a second gain — he ends up looking like the man who fixed it, having been the man who instituted it.
Greene records that this was not a one-off:
Cortés used this strategy often to deal with dissenters and troublemakers. At first he would seem to go along with their ideas, would even encourage them to take things further.1
In essence, he would get his enemies to expose themselves on a weak salient, where their selfish or unpopular ideas could be revealed. Now he had a target to hit.1
The military image is exact. A salient is a bulge in a line — a position that projects forward, so that its front is narrow and its flanks are long. It looks like an advance. It is the easiest thing on a map to cut off.
The reason this is necessary at all rests on an observation about how people argue in public:
When people present their ideas and arguments, they often censor themselves, trying to appear more conciliatory and flexible than is actually the case.1
Which produces a specific failure:
If you attack them directly from the front, you end up not getting very far, because there isn't much there to aim at.1
So the instruction inverts the reflex:
Instead try to make them go further with their ideas, giving you a bigger target. Do this by standing back, seeming to go along, and baiting them into moving rashly ahead. (You can also make them emotional, pushing their buttons, getting them to say more than they had wanted to.) They will expose themselves on a weak salient, advancing an indefensible argument or position that will make them look ridiculous.1
And the discipline that most people lack:
The key is never to strike too early. Give your opponents time to hang themselves.1
Striking early is what converts a salient back into a defensible line — because it hands the target a warning, and warned people retract.
Three conditions, visible in the case and not stated by Greene.
Their position must have a constituency it will offend. Cortés knew the gold policy would be hated by soldiers risking their lives for nothing. Baiting someone into an extreme position is worthless if nobody minds it.
The authorship must be unambiguous. The Velázquez men appointed the treasurer, from their own ranks, in the governor's name. That is why pointing worked. A policy adopted jointly cannot be pointed at.
And you must be able to survive the interim. The gold was actually collected. Cortés let a policy he opposed operate against his own men for a period, because the damage it did to his rivals was worth more than the damage it did to him.
Someone is undermining you and their stated objections are reasonable enough that attacking them makes you look defensive.
Stop attacking, because their position is deliberately moderate and there is nothing there.
Instead, agree. Then go one step further than agreeing: give them ownership of the implementation. Not consultation — ownership. Their name, their nominee, their process, their memo. This is the move, and it costs you the argument you were losing anyway.
Then let it operate, and be genuinely quiet. Do not editorialise, do not sabotage, do not warn anyone. The mechanism runs on the position being seen to be theirs while its consequences land on people who did not choose it. Anything you add gives them a way to attribute the outcome to you.
Then point rather than argue. When the complaints arrive, you have one job and it is factual: identify who instituted this. Cortés did not say the policy was bad. He said whose it was.
And then take the credit for the reversal. Rescind it at the request of the people it harmed. You entered the sequence as the man whose policy it wasn't and you leave it as the man who fixed it.
Two things to check before running this at all.
Timing. Striking too early is the standard error and it is fatal — a warned opponent retracts and you have taught them the technique. The instruction is to wait until the position is fully occupied and the constituency has noticed on its own.
And the interim cost, honestly. Cortés let his own soldiers be stripped of gold for weeks to make a political point. If the harm in the waiting period falls on people who are not party to the fight, you are spending them, and you should know that you are doing it rather than discover it afterwards.
The Velázquez faction, the tension over gold, and Cortés's manipulation of his own expedition are documented in the conquest sources — though those sources are overwhelmingly Spanish, largely partisan, and include Cortés's own letters to the king, which were written specifically to justify an expedition he had exceeded his authority to launch. [POPULAR SOURCE]
The most important thing about this case is what it is embedded in. Greene presents Cortés as a manager handling internal dissent, which is accurate and is also a description of a man consolidating command of an expedition that destroyed the Aztec state and initiated the deaths of a very large proportion of the population of central Mexico. The chapter takes from that campaign a portable technique for handling a difficult colleague. Everything the technique was used to accomplish is offstage.
This is the same pattern the vault has now logged repeatedly through this ingest, and Cortés is its clearest instance — Greene has used him three times across this book, for burnt ships, for a centre of gravity, and for this, and has never once described what the campaign did.
And the technique has a specific failure mode Greene doesn't name. It requires letting a policy you oppose actually run. If your read of the constituency is wrong — if the soldiers had accepted the gold policy, or if the Velázquez men had implemented it competently and made it popular — you have handed your rivals a genuine administrative win and an institutional foothold. The manoeuvre is presented as low-risk because it worked; it is in fact a bet on your own reading of who will be angry.
Against Cortés and the Burnt Ships, built in Cluster A, the two pages are the same man in the same year on the same beach — and the ordering matters more than either chapter says. The ships were scuttled to eliminate the option of return; the Velázquez faction were the people most likely to take it. You cannot burn the boats while a coherent faction wants to sail home, which means the salient manoeuvre described here is a precondition for the Strategy 4 case, not a separate lesson. Greene tells them fifteen chapters apart and never connects them.
Against Erickson and the Utilization Technique, the structural resemblance is close: encourage the resistance, take direction of it, let the person's own behaviour produce the outcome. The difference is the target of the damage. Erickson's patient was encouraged into behaviour that helped them; Cortés's rivals were encouraged into behaviour that destroyed them. Same instrument, opposite direction of interest — which is the distinction Greene declines to draw anywhere in the book.
Against Strategy 9: The Counterattack Strategy this is patience as the operative skill — let them move first, let them commit, and hit what the commitment exposed.
Behavioral Mechanics → Ownership as the Load-Bearing Variable. The technique's power comes almost entirely from attribution. The same policy, imposed by Cortés, would have made him hated; imposed by his rivals, it destroyed them.
The insight the pairing produces: in any organisation, the political cost of a decision attaches to whoever is visibly its author, almost independently of who actually wanted it — which means authorship is a transferable liability and is transferred constantly, usually without either party noticing the transaction. This reframes a very common experience: the manager who "empowers" a team to own an unpopular call, the executive who asks for a recommendation on something already decided, the committee formed to sign off on a foregone conclusion. The generous reading is delegation. The structural reading is that a liability has been moved, and the tell is whether the owner could have chosen differently. If they could not have said no, they have been given the salient rather than the authority.
Business → The Competitor Encouraged Into Their Own Extreme. Firms routinely destroy themselves by advancing a position their rivals were happy to let them advance — the aggressive pricing model, the licensing change, the platform policy that alienates the developers. The competitor who says nothing while it ships is not asleep.
The insight neither domain gives alone: the constituency that punishes an overextension is almost never the one being argued with, which is why the party making the move so rarely sees it coming. The Velázquez men were arguing with Cortés and were destroyed by the soldiers. A company changing its terms is negotiating with partners and is punished by users. This means the reliable predictor of whether an extension will become a salient is not how the direct counterparty responds but whether a third group with no seat at the table will notice and mind — and that group's absence from the negotiation is exactly what makes them invisible to the person deciding.
Cortés never argued that the gold policy was wrong. He gave it to the people who wanted it, let it operate, and pointed — and the position that had been unattackable while it was a criticism became indefensible the moment it became an administration. Which means the fastest way to defeat a reasonable-sounding objection is not to answer it but to make its author responsible for what it produces.
