Mahabharata 7.13.18

ततो व्यूढान्यनीकानि तव तेषां च भारत | शनैरुपेयुरन्योन्यं योध्यमानानि संयुगे

tato vyūḍhāny anīkāni tava teṣāṃ ca bhārata | śanair upeyur anyonyaṃ yodhyamānāni saṃyuge | āptair āśu parijñātaṃ bhāradvāja-cikīrṣitam ||

Sañjaya said: Then, O Bhārata, the battle-formations of your side and of theirs—arrayed in order—slowly moved toward one another for combat in the clash of war. And what the son of Bharadvāja (Droṇa) intended was swiftly understood through trusted informants.
