joint operation launched by British and Armenian troops dissolved it on 19 April 1919, arresting its leaders and sending them to Malta. In May 1919 Kars came under the full administration of the Armenian Republic and became the capital of its Vanand province. Skirmishes between the Turkish revolutionaries and Armenian border troops in Olti took place during the summer of 1920. In the autumn of that year four Turkish divisions under the command of General Kâzım Karabekir invaded the Armenian Republic, triggering the Turkish-Armenian War. Kars had been fortified to withstand a lengthy siege but, to the astonishment of all, was taken with little resistance by Turkish forces on 30 October 1920, in what some modern scholars have called one of the worst military fiascoes in Armenian history.
