[edit] Prelude

In 914 the Bulgarians had captured Adrianople, while the Byzantine army was occupied in the east. In 917, the empire had stabilized its eastern borders, and the generals John Bogas and Leo Phocas were able to gather additional troops from Asia Minor, perhaps as many as 110,000. Romanus Lecapenus commanded the fleet at the mouth of the Danube. The Bulgarians, under Simeon I of Bulgaria, had an army of only 70,000 men. The Bulgarians were afraid that the old allies of the Byzantines, the Pechenegs and the Hungarians, would attack them from the north, so two small Bulgarian armies were sent to protect the northern borders of the vast Bulgarian empire that spread from Bosnia in the west to Moldova in the east. John indeed tried to pay the Pechenegs to attack, but Romanus would not agree to transport them across the Danube, and instead they attacked Bulgarian territory on their own.

[edit] The battle

On [20 August] 917, the battle between the Romans and Bulgarians was fought by the river Acheloos (near the modern village Acheloi, 8 kilometers north from Anchialos (modern Pomorie) on [Bulgaria]'s [Black Sea] coast). The Romans were completely routed. Their headlong flight was punctuated by fearful cries as some men were trampled by comrades and others were killed by the enemy; there was such a letting of blood as had not been seen for very many years. [Leo Phokas] was saved by fleeing to Mesembria (modern [Nesebar] in [Bulgaria], but in the thick of the battle Constantine Lips, John Grapson and many other commanders (archontes) were cut down.

The battle was fought furiously. The decisive moment came when a heavy cavalry corps of Bulgarians, led by Simeon himself, attacked the Byzantine left wing from behind the hills. It is estimated that approximately 70,000 Byzantine soldiers died in this battle. The Byzantine historian Paulus Deakon says that 75 years after this military catastrophe the field at Anchialus was still covered with tens of thousands of Roman skeletons.

[edit] Aftermath

The remainder of the Byzantine army fled all the way back to Constantinople, followed by the Bulgarians, who defeated John again outside the city. The Byzantines proposed a new peace treaty, and Simeon entered the imperial city and was crowned for a second time as "Tsar" (the Slavonic title for Caesar) "of all Bulgarians and Greeks". Simeon also demanded that his daughter marry Constantine VII, the son of empress Zoe Karvounopsina, but Zoe refused and allied with Serbia and Hungary against him. However in August of 918, the general Romanus engineered a coup to depose Zoe and confine her to the monastery of St Euphemia-in-Petrium, allowing him to assume the purple.
