A second Senatorial embassy, this time including Pope Innocent I, was sent with Gothic guards to Honorius to plead with him to accept the Visigoths' demands. The imperial government also received word that Ataulf, Alaric's brother-in-law, had crossed the Julian Alps with his Goths into Italy with the intent of joining Alaric. Honorius summoned together all available Roman forces in northern Italy. He placed 300 Huns of the imperial guard under the command of Olympius, and possibly the other forces as well, and ordered him to intercept Ataulf. They clashed near Pisa, and despite his force supposedly killing 1,100 Goths and losing only 17 of his own men, Olympius was forced to retreat back to Ravenna. Zosimus seems to imply that only the Huns under Olympius took part in this fight. Ataulf then joined Alaric. This failure caused Olympius to fall from power and to flee for his life to Dalmatia. Jovius, the praetorian prefect of Italy, replaced Olympius as the power behind the throne and received the title of patrician. Jovius engineered a mutiny of soldiers in Ravenna who demanded the killing of magister utriusque militiae Turpilio and magister equitum Vigilantius; he had both men killed. Jovius was a friend of Alaric's and had been a supporter of Stilicho, and thus the new government was open to negotiations. Alaric went to Ariminum to meet Jovius and present his demands. Alaric wanted yearly tribute in gold and grain, and lands in the provinces of Dalmatia, Noricum, and Venetia for his people. Jovius also wrote privately to Honorius, suggesting that if Alaric was offered the position of magister utriusque militiae, they could lessen Alaric's other demands. Honorius rejected the demand for a Roman office, and he sent an insulting letter to Alaric, which was read out in the negotiations. Infuriated, Alaric broke off negotiations, and Jovius returned to Ravenna to strengthen his relationship with the Emperor. Honorius was now firmly committed to war, and Jovius swore on the Emperor's head never to make peace with Alaric. Alaric himself soon changed his mind when he heard Honorius was attempting to recruit 10,000 Huns to fight the Goths. He gathered a group of Roman bishops and sent them to Honorius with his new terms. He no longer sought Roman office or tribute in gold. He now only requested lands in Noricum and as much grain as the Emperor found necessary. Historian Olympiodorus the
