Srimad-Bhagavatam: Canto 10 - Chapter 1 - Verse 5

Sanskrit:

भगवान् पुनराव्रज्य पुरीं यवनवेष्टिताम् ।हत्वा म्‍लेच्छबलं निन्ये तदीयं द्वारकां धनम् ॥ ५ ॥

ITRANS:

bhagavān punar āvrajyapurīṁ yavana-veṣṭitāmhatvā mleccha-balaṁ ninyetadīyaṁ dvārakāṁ dhanam

Translation:

The Lord returned to Mathurā, which was still surrounded by Yavanas. Then He destroyed the army of barbarians and began taking their valuables to Dvārakā.

Purport:

It is clear from this verse that Kālayavana alone pursued Lord Kṛṣṇa into the mountain cave. When Kṛṣṇa returned to the besieged city of Mathurā, He eliminated the vast barbarian army.
