Śrīmad-Bhāgavatam · Text 6.10.29
Who is speaking and story frame
ते स्वप्रयासं वितथं निरीक्ष्य
हरावभक्ता हतयुद्धदर्पा: ।
पलायनायाजिमुखे विसृज्य
पतिं मनस्ते दधुरात्तसारा: ॥ २९ ॥
te sva-prayāsaṁ vitathaṁ nirīkṣya
harāv abhaktā hata-yuddha-darpāḥ
palāyanāyāji-mukhe visṛjya
patiṁ manas te dadhur ātta-sārāḥ

Leaving aside their leader even in the very beginning of the fight, they decided to flee because all their prowess had been taken away by the enemy.
