अनृत्वभूमिप्राप्तयोरनृतुप्राप्तं यथर्तुयुग्यशस्त्रावरणं युध्येत नाभूमिप्राप्तमवरुद्धप्रसारव्यायामम् ॥ कZ_०८.५.०७ ॥
anṛtvabhūmiprāptayor anṛtuprāptaṃ yathartuyugyaśastrāvaraṇaṃ yudhyeta nābhūmiprāptam avaruddhaprasāravyāyāmam
Between one that has arrived in an unseasonable time and one that has not yet reached suitable ground, he should fight the one that has arrived out of season—though equipped with season-appropriate arms and protection; he should not fight one that has not reached its ground and whose movement and exercise are constrained.
Kautilya treats season and ground as determinants of mobility and supply; engage when the opponent’s timing is suboptimal but they are still concentrated enough for decisive action.
