Satrughna had two sons, named Subahu and Srutasena. When Lord Bharata went to conquer all directions, He had to kill many millions of Gandharvas, who are generally pretenders. Taking all their wealth, He offered it to Lord Ramacandra. Satrughna also killed a Raksasa named Lavana, who was the son of Madhu Raksasa. Thus He established in the great forest known as Madhuvana the town known as Mathura.
