Polish forces pushed eastward, taking Kiev in May 1920. Following a strong Soviet counteroffensive, Prime Minister Władysław Grabski sought Allied assistance in July. Under pressure, he agreed to a Polish withdrawal to the 1919 version of the line and, in Galicia, an armistice near the current line of battle. On 11 July 1920 Curzon signed a telegram sent to the Bolshevik government proposing that a ceasefire be established along the line, and his name was subsequently associated with it.
