After securing Ghazza and achieving a victory Battle of Adjnadayn, the Islamic forces marched against Kaysariyya and established a siege for the second time in a row. Although historical accounts vary on who was in command when the forts of Kaysariyya were captured, the generally accepted version claims that Amr b. Al-Asi departed to Egypt shortly after taking up the siege again, leaving his successor Yazid b. Abi-Sufyan in charge, who in turn died and was succeeded by his brother Muawiya b. Abi-Sufyan. Kaysariyya was captured, the story continues, in the year 19 under the command of Muawiya.
