Then Rai Chach marched against Agham Lohanah. Agham had gone from Brahmanabad on a tour in his territory. When he heard of Chach’s coming, he returned to Brahmanabad, and began to collect soldiers and arms. When Rai Chach arrived at Brahmanabad, Agham, ready for battle, came forth to meet him. After several renowned warriors were killed on both sides, Agham’s army was put to spiritual guide. When Agham betook himself to the fort, the Samani co-operated with him, but did not join in the fight. He was busy reading his books in his temple. When Prince Agham died, and his son was established in the government of the country, the Samani became anxious and afraid lest the principalities, property and estates should pass away from his (the Samani’s) hands. In that perplexity, he consulted his books in order to ascertain the decree of fate, and he learnt that the kingdom was destined to fall into the hands of Chach, whether he himself was favourably inclined towards Chach or not. Agham’s son (eventually) was sore pressed, and his army withdrew from the fight, and the fort fell into the hands of Chach, who kept a strong hold on it.
