were rejected by Bonus, and the siege began on July 29. Bonus was the overall commander of the defenders. During the first five days of the siege, he sent repeated embassies to try and persuade the khagan to withdraw, offering money in return. The presence of a Persian embassy in the khagans tent on the fifth day underscored the danger the city would be in if the Avars' Slavic allies managed to ferry the Persian army over the

strait. Thus, on the tenth day of the siege, August 7, as the Avar assault peaked, Bonus lured the Slavs into a trap: the Byzantines had learned that the signal for the Slavic fleet to cross the strait and rendezvous with the Persian forces would be the lighting of a great fire. Therefore, the Byzantines themselves lit a beacon in

, sallied forth and decisively defeated them.
Following this success and the repulsion of the Avars from the walls, Bonus had to restrain the over-eager people of the city, including women and children, who wanted to rush out and capture the enemy siege engines. Instead, on August 8, the Avars began withdrawing; Bonus, Patriarch Sergius, and many people came to the Golden Gate to watch their retreat and the burning of the siege towers, set on fire by the Avars themselves. The Byzantine emperor's brother, Theodore, arrived soon after at the head of an army, and took up the running of affairs in the capital. Shortly after this, in early May 627, Bonus died and was buried (on May 11) in the Monastery of St John of Stoudios.
