792 battle of the Byzantine-Bulgarian Wars
The Battle of Marcellae (Bulgarian: Битката при Маркели; Greek: Μάχη των Μαρκελλών) was fought in 792 between the forces of the Byzantine Empire, led by Constantine VI, and those of the First Bulgarian Empire under Kardam. The Byzantines were routed and forced to retreat to Constantinople. Fighting took place at Marcellae (Markeli), near the modern town of Karnobat in southeastern Bulgaria, the same site as an earlier battle in 756.
Prelude
In the last quarter of the 8th century Bulgaria overcame the internal political crisis after the end of the rule of the Dulo. The khans Telerig and Kardam managed to consolidate the central authority and put an end of the quarrels among the nobility.[1] The Bulgarians finally had the opportunity to intensify their campaigns in Slavic-populated Macedonia. In 789 they penetrated deep into the valley of the Struma river and heavily defeated the Byzantines, killing the strategos of Thrace Filites. In order to distract the Bulgarian attention from Macedonia, the Byzantine emperor Constantine VI started a campaign in northern Thrace in April 791. The armies met near the fortress of Provat (20 km east of Odrin) and the Byzantines were forced to retreat, but their defeat was not decisive and in the following year the campaign was renewed.[2]
Battle
In the summer of the next year Constantine VI led his army north and on 20 July was confronted by the Bulgarians under Kardam near the border castle Marcellae. The Bulgarians had built ramparts blocking the roads to the Rish Pass and the capital Pliska. For several days the emperor did not dare to attack but by the end of July he was convinced by "false astrologists" (according to the Byzantine chronicler Theophanes the Confessor) that the stars boded victory and attacked.[3][4] Before the beginning of the battle, while awaiting the Byzantine assault, the Bulgarian ruler secretly placed part of his cavalry behind the hills surrounding the battlefield.[5]
Due to the rugged terrain the advancing Byzantine army broke its order. Taking advantage of that mistake, Kardam ordered a counterattack which brought the Bulgarians a great success.[6] The Bulgarian cavalry went round the Byzantines and cut their way back to their fortified camp and the fortress of Marcellae.[5] The Bulgarians took the supplies, the treasury and the tent of the emperor. They chased Constantine VI to Constantinople, killing a great number of soldiers. Many Byzantine commanders and officers perished in the battle.[6][7]
A weapon called arkani was used by the Bulgarians in this battle: the arkani consisted of a long pole with an attachment similar to a lasso at one end. It was an excellent weapon against cavalry as the rider could easily be pulled out of the saddle by a skilled warrior, armed with the arkani.[citation needed]
Aftermath
After the defeat, Constantine VI had to conclude peace with Kardam and had to pay tribute. Four years later the emperor stopped the payment, leading to a new war in Thrace which ended without a decisive battle.[8] The hostilities between Bulgaria and Byzantium continued under Kardam's successor Krum.[citation needed]
The victory had great political significance.[citation needed] The decades of crisis in Bulgaria were finally overcome. Bulgaria entered the 9th century consolidated, stronger and united which was an important factor for the string of victories scored by Krum against the Byzantines.[citation needed]
