Rome. The municipal infantry and knights move toward the Vatican, intending to do battle with the Pope and the newly crowned Frederick Barbarossa. Barbarossa has a mixed contingent of Teutonic and Lombard soldiers, while his cousin Henry the Lion supports him with a thousand Saxon and Bavarian knights. Henry, with his contingent, carries out a wide flanking maneuver, passing outside the Aurelian Walls, and attacks the citizens, who eventually disperse. Many are killed, others throw themselves into the Tiber, and approximately 300 surrender to Frederick. Of the latter, some are hanged as an example, and the others are freed after paying a large ransom. Frederick then stops in the Lazio countryside to consolidate his position, but the Roman heat arrives, and with it the Anopheles mosquitoes, carriers of malaria. Hundreds of Teutonic soldiers fall ill.
