Tallinn (Reval) was occupied on 25 February 1918, and in the rest of the Estonian mainland the last town captured by German forces was Narva (Narwa) on 4 March 1918.For the time being, the German advance put an end to both the Estonian Provisional Government which had declared the country independent on 24 February 1918 in Tallinn, as well as to the remaining Bolshevik Russian Red Guards in Estonia.During this whole period the Estonian Salvation Committee continued its underground activities, entering into relation with the Western Allied powers.After the German Revolution, between 11 and 14 November 1918, the representatives of Germany formally handed over political power in Estonia to the national government.When signing the Treaty of Brest-Litovsk on March 3, 1918, Soviet Russia formally transferred Estonia to German military administration, its future status having to be determined later.Tallinn, Tartu, and Narva were placed direct under the German military administration (Ober Ost), but the rest of the country was divided and administered as Amtsbezirks and smaller Ortsbezirks.
