Sima Yi
A thousand li in eight days
Their schedule is built on your procedure
Book of Jin, Annals of Emperor Xuan
Your opponent has your arrival time worked out precisely. What he got wrong is not the distance but whether you keep to the rules.
What actually happened?
In 227 Meng Da was plotting at Xincheng to leave Wei and go back to Shu. He had done the arithmetic in a letter to Zhuge Liang. Wancheng is eight hundred li from Luoyang and twelve hundred from me; when Sima Yi hears, he must first memorialise the throne and wait for a reply, and that is a month, and by then my walls will be finished. Sima Yi did not memorialise. He marched at once and was under the walls in eight days. Meng Da's next letter is stunned: I raised my standard eight days ago and the army is already here. Sixteen days later the city fell.
Their timetable is a list of your openings
Every item in Meng Da's arithmetic was right. The single error was assuming the other man would complete the procedure. Any plan resting on he must finish this before he can do that is writing your opponent's choreography for him, and he is free to decline to dance.
They have always shipped at quarter end, so every defence is scheduled for quarter end. The real threat arrives when they do not need that process.
Acting before reporting has a price
Marching without a memorial exceeded his authority and he would answer for it afterwards. His justification was arithmetic: spending a month of supply against a year of preparation only makes sense if it is fast. The value of speed has to cover the cost of breaking the rule, or it is recklessness.
Skipping the review to catch a window requires a sum afterwards showing the window was worth nothing otherwise. Without the sum it is only rule-breaking.
Timing matters more than strength
His reading before marching was that Meng Da had no credit with anyone, that this was the moment of mutual suspicion, and that he should be forced to a decision before things settled. The target was not a weakness but a window of confusion that would not stay open.
The two months after a rival's leadership change, while they are still aligning inside, is the cheapest window to take accounts. Later the same move costs triple.
How do I use it today?
Where you are: you are moving at the ordinary tempo and it feels like there is still time.
Ask first: does any part of their plan rest on my going through every step in order?
Where it goes wrong: calling rule-breaking decisiveness without being able to price the speed; and watching their strength while ignoring the weeks when they are internally at their most confused.
Lines to keep
He did not report. He was under the walls in eight days.
A month of supply against a year of it. Only speed justifies it.
