France, Italy and Britain called on Mustafa Kemal to enter into cease-fire negotiations. In return, on 29 September Kemal asked for the negotiations to be started at Mudanya. Negotiations at Mudanya began on 3 October and it was concluded with the Armistice of Mudanya. This was agreed on 11 October, two hours before the British intended to engage at Chanak, and signed the next day. The Greeks initially refused to agree but did so on 13 October. Factors persuading Turkey to sign may have included the arrival of British reinforcements.
