The Palmyrenes entered Alexandria, and left a garrison of 5,000, although shortly after, Probus was alerted of the situation in Egypt and quickly returned there.[2] He recaptured Alexandria, but his success was short lived when the Palmyrene army regained control of the city.[2] Probus retreated to Babylon Fortress.[5] Although Timagenes, a native of Egypt with knowledge of the land, ambushed the Roman rear and captured the fortress. Tenagino Probus ended up committing suicide, and the Palmyrenes consolidated their dominion over Egypt.[5]
