After
Baybars was victorious, he marched unopposed to
Kayseri (Qaysariyya) in the heart of
Anatolia in triumph and entered the city on April 23, 1277; just over a week after the battle. There, he massacred the city's Christian population, but spared its Muslim inhabitants. The Muslim festival of
Eid al-Adha happened around this time. In this festival, Baibars forbade the beating of drums of good tidings telling his emirs: "How can I rejoice? I had believed that if 10,000 horsemen of my army were to meet 30,000 Mongols, I would defeat them. But I met 7000 Mongols with all my army. The Mongols aroused panic and my army lost heart. The Mongols defeated the Muslim Left. Without Allah's grace, they would have defeated us. If I met them, and they were equal to the Muslims in size, or larger than they, then the matter would not have turned out well". Following the
Eid al-Adha festival, Baibars left Rum and died in Syria soon after. In light of Baibar's victory, Pervâne attempted to draw in the Mamluks into a confrontation with a fresh Mongol army led by Abaqa himself. However, Baibars was running low on supplies, and his equipment needed repair. The possibility of a new Mongol army convinced Baibars to return to Syria since he was so far away from his bases and supply line. As the Mamluk army returned to Syria the commander of the Mamluk vanguard, Izz al-Din Aybeg al-Shaykhi defected to the Mongols. Pervâne sent a letter to Baibars asking him to delay his departure. Baibars chastised him for not aiding him during the Battle of Elbistan. Baibars told him he was leaving for Siwas to mislead Pervâne and the Mongols to his true destination. Baibars also sent Taybars al-Waziri with a force to raid an Armenian town called al-Rummana, whose inhabitants had hidden the Mongols earlier. The Mongol
Ilkhan Abaqa, meanwhile reasserted his authority in Rum. After Abaqa surveyed the battlefield he became very angry. He ordered the Muslim population of
Kayseri (Qaysariyya) and eastern Rum to be put to death. Large numbers of people were killed. Abaqa's army had to put down a rebellion of
Karamanid Turkmen who declared their loyalty to Baibars. He sent an army of 30,000 towards Syria, but after learning the size of Baibars army from Aybeg al-Shaykhi he called his forces back. He wanted to send the army in the summer but his officers persuaded him to wait until the winter. However, the expedition was never sent. The Ilkhan Mongols were having logistical problems of their own, and many of the troops were called back to Ilkhanate lands. Abaqa entrusted the country to his other brother Qonghurtai and Shams al-Din Juwayni. At first Abaqa turned a blind eye to
Pervâne. The
Mongol nobles and noblewomen convinced him to have him put to death. Pervâne's flesh was eaten by
Abaqa and the senior
Mongols as an act of revenge, according to King
Hethum II of
Armenian Cilicia. == Notes ==
