|Background story:||In 755, the long peace between Bulgaria and the Byzantine Empire came to an end. This was mainly because, after his victories over the Arabs, the Byzantine Emperor Constantine V began to fortify his border with Bulgaria. To this aim he resettled heretics from Armenia and Syria in Thrace. Khan Kormisosh took those actions, and the construction of a new fortress along the border, as a breach of the Treaty of 716, signed by Khan Tervel. The Bulgarian ruler sent envoys to ask for tribute for the new fortresses. After the refusal of the Byzantine Emperor, the Bulgarian army invaded Thrace. Looting everything on their way, the Bulgarians reached the outskirts of Constantinople, where they were engaged and defeated by Byzantine troops.
In the next year, Constantine V organized a large campaign against Bulgaria which was now ruled by a new Khan, Vinekh. An army was sent with 500 ships which plundered the area around the Danube delta. The Emperor himself, leading the main force, advanced into Thrace, and was engaged by the Bulgarians at the border castle of Marcellae.
Constantine won a bloody battle, though both sides suffered costly losses and agreed on a truce. Forces and casualties are not known. It must have been a large-scale battle, since it is known that in the campaign the Byzantines used 500 ships. The Bulgars later renewed the war and were defeated in June 763 at Anchialus.
