Quick answer

On 29 July 1014, the day and month given by John Skylitzes, Byzantine troops led by Nikephoros Xiphias came down from the mountains behind the army of Tsar Samuel of Bulgaria, which held a wall across the pass of Kleidion, near today's village of Klyuch. The Bulgarians fled, and Emperor Basil II broke through the abandoned wall. Skylitzes writes that Basil then blinded about 15,000 prisoners, "as they say", and sent them back to Samuel, each hundred led by a man left with one eye; Samuel collapsed at the sight and died two days later. Historians doubt the figure, and the name Bulgar-Slayer came generations later. On this day in 1693 the French won at Landen.

Also on this day

Landen, 1693. Near the village of Neerwinden, Marshal Luxembourg's French army defeated the allied army of William III. The Duke of Berwick, who fought on the French side, writes that Luxembourg's cavalry came in sight of the enemy on the 28th of July and that the battle was put off till "the next day, the 29th". The allied report in the London Gazette, datelined "July 30. N. S.", says that "On the 29th by break of day the Enemies whole Army came in sight of us", and Fortescue titles his plan "Landen, 19th (29th) July 1693". The Gazette says that the French were repulsed in all their attacks and the advantage lay with the allies until 4 in the afternoon, when the French took a village on the allied right and forced an entrenchment, and that the King "would never put on his Armour, though he was every where in the hottest of the Action". It puts the French at "above 80000 effective Men" and the allies at "not more than 45000"; Fortescue writes of "fifty thousand against eighty thousand". Berwick, captured that day by his uncle Brigadier Churchill, gives the allied loss as near 20,000 men and the French as at least 8,000; Fortescue gives about 8,000 French and about 12,000 allied killed, wounded and prisoners.1

Frequently asked questions

Who won the Battle of Kleidion?

Basil II's Byzantine army. According to John Skylitzes, Nikephoros Xiphias led a force round the mountain south of the pass and fell on the Bulgarians from behind, and Basil broke through their wall as they fled.

Did Basil II really blind 15,000 prisoners?

Skylitzes gives about 15,000, adding "as they say"; Kaloyan Kirilov writes of some 14,000. Georgios Theotokis calls the figure an exaggeration, Catherine Holmes suggests it was miscopied or exaggerated, and Paul Stephenson, as Timothy May summarizes him, argues that fewer were blinded.

When did Tsar Samuel die?

Skylitzes writes that he died two days after seeing his blinded men return. The date 6 October comes from a note added in one manuscript of Skylitzes; Kirilov and Theotokis give 6 October 1014.

When was Basil II first called the Bulgar-Slayer?

After his lifetime, according to modern historians. Stephenson, as May summarizes him, ties the name to twelfth-century politics, while Theotokis writes that it is not attested until the early fourteenth century.

Where was Kleidion?

Kirilov places the Bulgarian barrier in the gorge between the Belasitsa and Ograzhden mountains, at today's village of Klyuch near Petrich; Theotokis also puts the battle close to Klyuch.
