Acala and Vṛshaka

Acala and Vṛshaka were brothers of Śakuni, the king of Gāndhāra. Through Gāndhārī, who was Śakuni’s sister, they were maternal uncles of Duryodhana. Both fought in the Kaurava army. Bhīshma names both of them as rathas (chariot warriors) of the Kaurava side in his count of the warriors.

In the Kaurava army

Acala and Vṛshaka were among the brothers of Śakuni who fought on the Kaurava side. They belonged to the royal house of Gāndhāra, and with Śakuni they were part of the wider family that stood behind Duryodhana. They served as warriors in the Kaurava army. In the Rathātiratha-Saṃkhyāna, Bhīshma’s count of the rathas and atirathas (the greater chariot warriors), he rates both as rathas in the Kaurava host.

Reunion at the Gaṅgā

In the Āśramavāsika Parva, Acala and Vṛshaka rose from the sacred waters of the Gaṅgā among the host of the fallen warriors. They were young again and free of enmity. They were there for one night of reunion before they went back to their loka.
