Over these and the next few years, a regular pattern emerged: the Byzantines would campaign in Bulgaria, laying siege to forts and pillaging the countryside, while the numerically inferior Bulgarians, unable to offer direct opposition, launched diversionary raids in Macedonia and Greece.

 continued to invade Bulgaria each year and destroy and devastate everything on his way. Samuel could not stop him in the open field or engage the Emperor in a decisive battle, and suffered many defeats and began to lose his strength." The culmination of the war came in 1014, when Samuel, at the head of his army, resolved to stop the Byzantine army before it could enter the Bulgarian heartland.

Preparations for the battle

Samuel knew that the Byzantine army would have to invade the country through a series of mountain passes, and so took precautions to bar them. The Bulgarians built ditches along the frontier and fortified many of the valleys and passes with walls and towers, especially the pass of Kleidion on the Struma River

 which Basil would need to pass through to reach the heart of Bulgaria. Samuel heavily fortified the northern slopes of the Belasitsa mountain to the south and east of Strumitsa Castle. The wide valley of the Strumitsa River was a convenient place for attack and it had been used by Byzantine forces for this purpose in previous years. The Bulgarians disposed a strong guard to keep the pass safe. In addition, the Bulgarian ruler chose Strumitsa for his defensive base — it was located on the road from Thessaloniki leading to Thrace to the east and Ohrid

 to the west. The rugged terrain to the south was dotted with earthworks and walls guarded by strong Bulgarian units.

Samuel's decision to face Basil II and the bulk of his army at Kleidion was not only prompted by the constant defeats and invasions which had devastated the country, but also by concerns over his authority among the nobility, which had been fatally weakened by Basil's campaigns.

 had surrendered the town to Basil II. To face this threat, Samuel gathered a large army to face the Byzantines, some claiming it numbered as many as 45,000 soldiers. Basil II also prepared carefully, assembling a large army of his own and taking his most experienced commanders, including the governor of Philippopolis (modern Plovdiv

From there the army entered the Strumitsa valley and reached the vicinity of the village of Klyuch, where the river bent and approached Belasitsa and Ozgrazhden. There the army was stopped by a thick wooden wall, defended by Bulgarian soldiers. The Byzantines attacked the palisade immediately, but were repulsed with heavy casualties.

Basil II's first attempt to overwhelm the defenders of the pass was unsuccessful and his army was unable to pass through the valley, which was defended by 15,000–20,000 Bulgarians. Despite the difficulties the Byzantine Emperor did not abandon the attack. He ordered his general Nicephorus Xiphias to manoeuvre his troops around the high Belasitsa mountain and surround the Bulgarians, while he continued the assaults on the wall. Xiphias led his troops along a steep path that led him into the Bulgarians' rear. On July 29, Xiphias attacked the guards, trapping them in the valley. The Bulgarian soldiers abandoned their towers to face this new threat and Basil was able to break through the front line and destroy the wall.

In the confusion of the rout, thousands of Bulgarian troops were killed and the remainder desperately attempted to flee westwards. Samuel and his son Gabriel Radomir

The Byzantine Emperor also sent an army under Botaneiates to surround Strumitsa and destroy all ramparts to the south and clear the passage to Thessalonica. With the remainder of his troops, Basil laid siege to the city itself. The Bulgarians allowed Botaneiates to destroy the fortifications, but he and his army were ambushed by Bulgarian raiders in a narrow valley, soon after their task was complete. In the ensuing battle Botaneiates was completely defeated

 numbers the prisoners at 8,000. Basil divided the prisoners into groups of 100 men, blinded 99 men in each group and left one man in each with one eye so that he could lead the others home; this was done in retaliation for the death of Botaneiates, who was Basil's favourite general and advisor, and also to crush the Bulgarian morale. Another possible reason was that, in Byzantine eyes, the Bulgarians were rebels against their authority, and blinding was the usual punishment

 meted out to rebels. For this action, Basil gained the nickname Boulgaroktonos , "the Bulgar-slayer". Samuel died of a heart attack on October 6, 1014, reportedly due to seeing his soldiers blinded.

Aftermath

The death of Botaneiates and the four more years of war that followed indicate that the Byzantine success was not complete. Some modern historians doubt that the Bulgarian defeat was as complete as described by Skylitzes and Kekaumenos. Other historians emphasize that the death of Emperor Samuel two months later was much more fateful for Bulgaria. His heirs Gabriel Radomir

Other theses in the historiography stress the significance of the battle. As a result of the battle of Belasitsa, the Bulgarian army suffered heavy casualties that could not be restored. The ability of the central government to control the peripheral and interior provinces of the Empire was reduced and the actions of the local and provincial governors became more decisive for the outcome of the war with Byzantium. Many of them voluntarily surrendered to Basil II.
