Task: Question Generation
Input (English): In the north Eristov pushed southwest, fought two battles, forced the Turks back to Batum, retired behind the Cholok River and suspended action for the rest of the year (June). In the far south Wrangel pushed west, fought a battle and occupied Bayazit. In the center the main forces stood at Kars and Gyumri. Both slowly approached along the Kars-Gyumri road and faced each other, neither side choosing to fight (June–July). On 4 August Russian scouts saw a movement which they thought was the start of a withdrawal, the Russians advanced and the Turks attacked first. They were defeated, losing 8000 men to the Russian 3000. 10000 irregulars deserted to their villages. Both sides withdrew to their former positions. About this time the Persians made a semi-secret agreement to remain neutral in exchange for the cancellation of the indemnity from the previous war.
Output (English): Where did the main forces stand?
