Many historians argue that the main reason behind the Soviet agreement with Lithuania was to weaken Poland and hand the disputed territories to a weaker state, which Lithuania was at the time, in order to reconquer the area more easily after the retreat of the Red Army had halted. Also, the independence of the Baltic States was seen by Lenin as temporary. However, after the Battle of the Niemen River the Red Army was again defeated and Bolshevik Russia was forced to abandon her plans for reincorporation of all the lands lost by the Russian Empire in the Treaty of Brest-Litovsk.
