, and also along the valley of the Strymōn ( Struma) River. Many towns were seized and their population was sent far to the north to “ Bulgaria across the Danube”. The attack created such panic among the Byzantine population that several towns were emptied even without being attacked by the Bulgarians. The attempts of Michael I to resist were fruitless – he organized an army but soon after he set off from Constantinople as he had to go back due to a conspiracy. In the meantime the Bulgarians continued to strike Thrace, but in the autumn of 812 they were offered peace.

refused to conclude the peace deal due to "his foul advisors' suggestions". The real reason was ,most likely, item 3 in the Byzantine–Bulgarian Treaty of 716 which stated that "The refugees migrants, desertersfrom both sides shall be mutually surrendered, if they are plotting against the authorities." That item was important for the Byzantines during the 8th century because the authority of their former Emperors was weakened and, after the crisis in Bulgaria in the mid 8th century, it had become inconvenient for them. In response to the refusal, the Bulgarians besieged Mesembria (

He immediately took hasty precautions for the defense of Constantinople because he expected a Bulgarian assault.Theophanes Confessor, ''Chronographia'', p. 503 The way to Constantinople was clear and the Bulgarian army headed to the city without resistance. There were still several fortresses in Thrace which remained in Byzantine hands, particularly Adrianople which was besieged by Krum's brother.
