The religious conference was held by king Harshavardhana at Kannauj and Prayag. A courier brought the distressing intelligence that Grahavarman, king of Kannauj, and husband of Rajyasri, sister of the princes, had been slain by the King of Malwa, who cruelly misused the princess, "confining her like a brigand's wife, with a pair of iron fetters kissing her feet." The young king, resolute to avenge his sister's wrongs, started at once with a mobile force of ten thousand cavalry, leaving the elephants and heavy troops behind in his brother's charge.
