In the battle at the river Larisus between the Achaeans with their allies and the Eleans with the Aetolians,220-217 B.C who were helping the Eleans on grounds of kinship, Philopoemen first killed with his own hand Demophantus, the leader of the opposing cavalry, and then turned to flight all the mounted troops of Aetolia and Elis.
