Explain a defeat by shrinking whatever beat you, and you will schedule the same defeat somewhere else.
One loss generalized into a law about where power lives becomes a feeling of certainty the moment it explains something painful, and an explanation that demands no change from the men holding it is the kind that never gets tested. That certainty set the strategy, the strategy chose the ground, and an entire army moved on a theory no one had checked.
Nothing about their own conduct came under review; the fault went to hills. Fitting Yahweh inside a range limit was the actual error, and the flat ground removed the last excuse when the second defeat came. A diagnosis that blames terrain protects a man's pride and costs him the next campaign, which he enters certain he has solved something.
