 Pompey, for whatever reason, decided to comply and both men drew up their armies for battle.They fought a pitched battle at the River Sucro; and although Sertorius defeated the left wing of Pompey's army (even forcing Pompey himself to flee the battlefield) his other wing was defeated by Pompey's legate Afranius, so the end result was a draw.When word came of Metellus's immanent arrival, Sertorius marched inland with Pompey and Metellus in pursuit.
