سيف الدولة الحمداني
After his establishment in Aleppo, in winter 945–946 Sayf al-Dawla launched his first raid into Byzantine territory, but a truce was arranged and regular warfare between Sayf al-Dawla and the Byzantines began only in 948. Initially, the Byzantines were led by the Domestic of the Schools (commander-in-chief) Bardas Phokas the Elder, but although he was capable enough as a subordinate commander, his tenure as commander-in-chief proved largely a failure. In 948–950 the Byzantines scored a few successes, sacking the border fortresses of Hadath and Marash, and taking Theodosiopolis, putting an end to the Muslim border emirate there. Bardas' second son, Leo, distinguished himself in these years, leading the capture of Hadath and a raid that reached the outskirts of Antioch and defeated a Hamdanid army. In November 950 Leo scored a major success against Sayf al-Dawla, who had previously advanced deep into Byzantine Asia Minor from Cilicia and defeated Bardas in battle. Leo ambushed the Hamdanid army during its return journey in a mountain pass; Sayf al-Dawla lost 8,000 men and barely escaped himself.
