The campaign itself is finished by this line, and what remains is judgment about its aftermath rather than any further action within it. A yin stroke stands in an even position, correctly placed by the standard rule, at the very top of the hexagram, the station classical commentary treats as spent or passing, a situation that has run its course rather than one still actively unfolding. When this line changes, the top stroke of Kun becomes firm, turning the upper trigram into Gen, the mountain that keeps still, while the lower trigram Kan remains fixed below.
The resulting hexagram is Number 4, Youthful Folly, mountain over water, an image of inexperience and untested capacity in need of patient instruction rather than premature responsibility. That the line's own warning against giving lasting charge to small, undisciplined men should transform into the hexagram most concerned with immature judgment needing guidance is a pointed final echo, closing The Army not on the memory of the campaign itself but on the ongoing question of who is, and who is not yet, ready to be trusted with what it won. Read across the whole hexagram's six lines, this final change completes a movement from the discipline needed to begin a campaign to the discipline needed to end one honestly, both resting on the same insistence that position alone never substitutes for genuine capability.
