Alerted to the advance, Petronius again marched south and managed to reach Qasr Ibrim and bolster its defences before the invading Kushites arrived. Although the ancient sources give no description of the ensuing battle, we know that at some point the Kushites sent ambassadors to negotiate a peace settlement with Petronius and possibly accept a status like "Client State" of Rome. By the end of the second campaign after other years of fighting, however, Petronius was in no mood to deal further with the Kushites.
