The Ecclesiastical History of Sozomen

About this period the dissensions by which the Church was agitated were followed, as is frequently the case, by disturbances and commotions in the state. The Huns crossed the Ister and devastated Thrace. The robbers in Isauria gathered in great numbers and ravaged cities and villages as far as Caria and Phœnicia. Stilicho, the general of Honorius, a man who had attained great power, if any one ever did, and had under his sway the flower of the Roman and of the barbarian soldiery, conceived feelings of enmity against the rulers who held office under Arcadius, and determined to set the two empires at enmity with each other. He caused Alaric, the leader of the Goths, to be appointed by Honorius to the office of general of the Roman troops, and sent him into Illyria; whither also he dispatched Jovius, the prætorian prefect, and promised to join them there with the Roman soldiers in order to add that province to the dominions of Honorius. Alaric marched at the head of his troops from the barbarous regions bordering on Dalmatia and Pannonia, and came to Epirus; and after waiting for some time there, he returned to Italy. Stilicho was prevented from fulfilling his agreement to join Alaric, by some letters which were transmitted to him from Honorius. These events happened in the manner narrated.
