Preparations for battle

Both sides carefully prepared for a decisive end of the conflict. Empress Zoe wanted to swiftly make a peace settlement with the Arabs and to engage the whole army of the East in a war with Simeon and destroy him.

 but Simeon was familiar with the methods of Byzantine diplomacy and from the very beginning took successful actions to subvert a possible alliance between his enemies. Thus the Byzantines were forced to fight alone.

The Byzantine commanders were convinced that their strategy would be successful. Morale was raised as the soldiers vowed by the miraculous Wooden Cross to die for one another.

 coast. The Byzantine generals planned to outflank the right Bulgarian wing in order to detach Simeon's troops from the Balkan Passes. The Bulgarian ruler concentrated his most powerful forces in the two wings and left the centre relatively weak in order to surround the enemy when the centre would yield to the Byzantine attack. Simeon himself was in charge of large cavalry reserves hidden behind the hills who were supposed to make the decisive blow.

The Byzantine attack was fierce and it was not long before the Bulgarians began slowly to retreat. The enemy cavalry charged the infantry in the centre killing many Bulgarians. The Bulgarian position became desperate as they could not manage to hold the heights to the south of the river and began a hasty retreat to the north. Elated, the Byzantines started a bitter chase and their battle formations soon began to break. The battle was fought furiously. The decisive moment came when the heavy cavalry corps of Bulgarians, led by Simeon, attacked the Byzantine left wing from behind the hills. With an irresistible rush the cavaliers dashed down at the confused enemy who immediately bent under their attack, panicked and took on their heels.
Some Byzantines tried to repulse the cavalry charge but they were also attacked by the infantry. Tsar Simeon personally took part in the fight, his white horse killed at the height of the battle. The Byzantines were completely routed. Leo Phocas was saved by fleeing to Mesembria (modern NesebarNesebar

, but in the thick of the battle Constantine Lips, John Grapson and many other commanders (archontes) were cut down along with enormous number of soldiers and officers. By the end of the day the Bulgarians overwhelmed the defenders of Mesembria and captured the town. Leo Phocas barely escaped boarding a ship.

It is estimated that approximately 70,000 Byzantine soldiers died in this battle. The Byzantine historian Leo Diaconus says that 75 years after this military catastrophe the field at Anchialus was still covered with tens of thousands of Roman skeletons. With a total of 90,000 killed the battle was among the bloodiest in the whole Medieval history and some historians refer to it as "the battle of the century".

Significance

The battle of Anchialus was one of the most important battles for Bulgaria. It secured the Imperial title of the Bulgarian rulers of centuries which was a considerable humiliation for the Byzantine Empire whose rulers claimed to have been God's only representatives on Earth. The battle also secured the survival of the Bulgarian state as the main objective of the 110,000 enemy army was to eliminate its dangerous northern neighbour.
