In the spring of 70 CE, Roman forces breached the "third wall", then the "second wall" and by summer had taken control of the Antonia. The Zealots still maintained control of the temple compound and the upper city, but on Tisha B'Av (August 10) 70 CE, Roman forces overwhelmed the defenders and set fire to the temple. Jewish resistance continued but a month later the upper city was taken as well and the entire city burnt to the ground, save for the three towers of the Herodian citadel which Titus spared as testimony to the city's former might.[1] According to Josephus, over a million people had died in the siege and subsequent fighting.
