Srimad-Bhagavatam: Canto 6 - Chapter 1 - Verse 29
Sanskrit:
ते स्वप्रयासं वितथं निरीक्ष्यहरावभक्ता हतयुद्धदर्पा: ।पलायनायाजिमुखे विसृज्यपतिं मनस्ते दधुरात्तसारा: ॥ २९ ॥
ITRANS:
te sva-prayāsaṁ vitathaṁ nirīkṣyaharāv abhaktā hata-yuddha-darpāḥpalāyanāyāji-mukhe visṛjyapatiṁ manas te dadhur ātta-sārāḥ
Translation:
The asuras, who are never devotees of Lord Kṛṣṇa, the Supreme Personality of Godhead, lost their pride in fighting when they found all their endeavors futile. 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.
