आशानिर्वेदिपरिसृप्तयोराशानिर्वेदि लब्धाभिप्रायं युध्येत न परिसृप्तमपसृतमुख्यम् ॥ कZ_०८.५.०८ ॥

Between one whose intention is known and one that has dispersed, he should fight the one whose aim has been ascertained; he should not fight the dispersed force whose main body has withdrawn.
Prefer engagements with clear enemy intent and identifiable center of gravity; avoid fighting a dispersed adversary when the main body has already slipped away (costly, inconclusive operations).
