The Battle of Pliska or Battle of Vărbitsa Pass was a series of battles between the forces of the Byzantine Empire under Emperor Nicephorus I, and the First Bulgarian Empire under Khan Krum in July 811. The Byzantines plundered and burned the Bulgar capital Pliska which gave time for the Bulgarians to block passes in the Balkan Mountains that served as exits out of Bulgaria. The final battle took place on 26 July 811, in some of the passes in the eastern part of the Balkans, most probably the Vărbitsa Pass. There, the Bulgarians used the tactics of ambush and surprise night attacks to effectively trap and immobilize the Byzantine army, thus annihilating almost the whole army, including the Emperor. After the battle, Krum encased the skull of Nicephorus in silver, and used it as a cup for drinking. This is one of the most documented instances of the custom of the skull cup. The Battle of Pliska was one of the worst defeats in Byzantine history.
