due to a mutiny of his troops at Adrianople. The following year, the Bulgarians, in response to an equestrian raid in the valley of the Struma River, defeated the Byzantines and captured their baggage.

The siege

In the spring of 809, Krum took the offensive and surprised the Byzantines by besieging Serdica. The garrison held out for several weeks even as food supplies shrunk and the number of men declined due to desertions and the release of mercenaries. At Easter, the Byzantines were ready to surrender the fortress. Krum promised to give safe conduct to the Byzantines on condition they yield the fortress. The Byzantines agreed and Krum entered Serdica before Easter. Despite Krum's promise of safe conduct, he killed the entire garrison of 6,000 along with some of the citizens. Nikephoros was unhappy with those Byzantines who abandoned the garrison and those who defected to the Bulgarians. One of those defecting was the highly skilled mechanic Evmat who would help Krum later on with the construction of siege machines.
