On 26 January 1918, a workers' uprising sparked the Finnish Civil War and the establishment a few days later of the Finnish Socialist Workers' Republic. More Jägers and equipment arrived from Germany to bolster the anti-socialist Finnish forces on 17 and 25 February. The armistice with the Central Powers expired on 18 February, and Soviet Russia and the Finnish workers' republic signed a treaty of friendship on 1 March 1918. Nevertheless, on 3 March Russia signed the Treaty of Brest-Litovsk and made peace with the Central Powers.
