text: His next step was to send Alinaq with 15,000 men against Arghun, while he himself followed Alinaq on 26 April with his main army composed of Armenians and Georgians in addition to Mongols stationed in Mughan plain near Bilasuvar. Arghun prevailed against Alinaq in battle on 4 May, south of 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 negotiate a truce, which Ahmad, against the advice of his councillors, refused. Another embassy sent by Arghun, this time led by his son Ghazan arrived at Tekuder's camp near Semnan on 31 May. The embassy was a success, as Ahmad accepted a truce on the condition that Arghun send his brother Gaykhatu as a hostage. Arghun agreed to the terms and sent his brother accompanied by two amirs, including Nawruz into the custody of Buqa, then the most senior of Tekuder's commanders, on 13 or 28 June. Buqa in turn handed him over to Ahmad who put Gaykhatu in Tödai Khatun's encampment.
  Despite this, Tekuder continued hostilities and continued to advance on Arghun. This caused Buqa to harbour resentment towards Tekuder and to grow more sympathetic to Arghun. On the other hand, he lost the favour of Tekuder who started to invest his trust in Aq Buqa, another Jalair general.
  Arghun's next step was to seek 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 in Alinaq's custody while he himself left for Kalpush, where his main army was stationed. This was the 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 the Golden Horde via Derbent. However, Qaraunas, who had been sent by Buqa, soon caught up with and arrested Tekuder. He was turned over to Arghun on 26 July on the Ab-i Shur pasturelands, near Maragha.
