"In short, you treated securing Ostenso as a military operation and conducted it, from what you say, in very good order," she says coolly, smoothly, "But a military camp generates no tax revenue, and so a city is not a military operation, and cannot be run as such." She shrugs slightly and continues, "Ostenso was a modest failure, sir, not a success, and you did not observe this because you had neither the time nor the tools to see it."
"Firstly, the tools. What you did may work to establish certainty in Taldor, but it does not work in Cheliax. The lower classes, especially of the city, do not believe in any such thing. For the next generation, or longer if we are unlucky or unskilled, every city in Cheliax will be expecting arbitrary cruelty, and crackdowns which are pointlessly brutal and revel in their excessive brutality, from its guard, in response to anything and nothing." She pauses to make vaguely placating wave. "I do not mean to impugn your men's discipline, but that would be true even if it were spotless, and we know perfectly well that it is not, not unless you lead paladins. Determining the actual state of impulse to unrest requires a network of observers or informants to keep tabs on how discontent the rioting classes are when they are out of sight of their governors. What you do then has a great deal of variation based on circumstances and the aptitudes of your staff, of which preemptive crackdowns are the most common option but one of the least effective."
"Secondly, the time. From my experience, in my own city and others, such a policy does not work in the long term, with problems generally seen within six months and always within a year. It suppresses riots, but the factors that drive them remain to emerge at the next opportunity, leading to more deaths and property damage in the city over time. It also requires substantially higher guard mobilization, across substantially larger fractions of the year, than a more politically-oriented mix of methods; an expense we can ill-afford, especially at present. Again, those other methods have many variations, most of them ungentlemanly; I needed to simultaneously support a nascent rebellion against the Thrunes and so had to work by earning loyalty, but well-run secret police can also be effective, and targeted bribery works more cheaply than you'd expect."
"I mean no insult whatsoever to your character or intelligence, Captain; many sensible military men have made these same mistakes before you, and many more will make them after you. Your skill and expertise would be an asset any lord mayor would be pleased to rely on, did you offer them to him, and I am surprised you have not yet been offered another holding - a coastal county, likely, if I understood your nautical background right. With experience you would learn some of the other skills and then be a good candidate for the mayorship in a few years. But the situation is too delicate at present, and we cannot wait; the Lord Mayor cannot be you. Has anyone else a candidate to recommend? Duke de Fraga? Ser Cansellarion?"
