day. Another contingent of army was sent to Jazira, from where Gaykhatu and Baydu fled to Khorasan, to Arghun's encampment while several emirs such as Taghachar and Doladai were arrested. Arghun started an open rebellion upon his return from Baghdad to Khorasan in 1283 to gain allegiance of minor nobles and amirs. Tekuder's next step was to send Alinaq with 15.000 men against Arghun on 29 January, while ilkhan himself followed Alinaq on 26 April from his main army composed of Armenians and Georgians in addition to Mongols stationed in Mughan plain near Bilasuvar. Arghun prevailed on Alinaq in battle on 4 May south to Qazvin but nevertheless retreated to his lands in Khorasan. Ala ud-Daula Simnani, future Sufi saint of Kubrawiya order also fought in Arghun's army during this battle. Arghun tried to make truce on halfway, which Ahmad against advices of his councillors, refused it. Another embassy sent by Arghun, this time led by his son Ghazan arrived at Tekuder's camp near Semnan on 31 May. Embassy was a success, as Ahmad accepted truce on condition if Arghun sends his brother Gaykhatu as a hostage. Arghun agreed to terms and sent his brother accompanied by two amirs, including Nawruz to custody of Buqa, then most senior of Tekuder's commanders on 13 or 28 June. Buqa in turn handed over him to Ahmad who put Gaykhatu in Tödai Khatun's encampment. Despite this, Tekuder continued hostilities and kept advancing on Arghun. This made Buqa to harbor resentment towards Tekuder and grow more sympathetic to Arghun. On the other hand, he lost Tekuder's favor who started to invest his trust in Aq Buqa, another Jalair general. Seeing developments, Arghun sook refuge in Kalat-e Naderi, a strong fortress on 7 July with 100 men. But he was forced to surrender to Alinaq four days later. Victorious Tekuder left Arghun at Alinaq's captivity while himself left for Kalpush, where his main army was stationed. This was an opportunity Buqa was seeking - he broke into Alinaq's camp and set Arghun free, while killing Alinaq. Tekuder fled west and looted Buqa's encampment near Sultaniya in revenge. He continued on to his own pasturelands near Takht-i Suleyman on 17 July planning to escape to Golden Horde via Derbent. However, Qaraunas sent by Buqa soon caught up with him and arrested Tekuder. He was turned over to Arghun on 26 July on Ab-i Shur pasturelands, near
