In 535, the Roman general Mundus invaded Dalmatia, and Belisarius, with an army of 7,500 men, captured Sicily with ease. From there, in June next year, he crossed over to Italy at Rhegium. After a twenty-day siege, the Romans sacked Naples in early November. After the fall of Naples, the Goths, who were enraged with the inactivity of their king, Theodahad, gathered in council and elected Vitiges as their new king. Theodahad, who fled from Rome to Ravenna, was murdered by an agent of Vitiges on the way. In the meantime, Vitiges held a council at Rome, where it was decided not to seek immediate confrontation with Belisarius, but to wait until the main army, stationed in the north, was assembled. Vitiges then departed Rome for Ravenna, leaving a 4,000 strong garrison to secure the city.
