Paasikivi, and the Senate asked the German troops to remain in Finland. 3 March 1918 Treaty of Brest-Litovsk and 7 March German-Finnish agreements bound White Finland to the German Empire's sphere of influence. General Mannerheim resigned his post on 25 May after disagreements with the Senate about German hegemony over Finland, and about his planned attack on Petrograd to repulse the Bolsheviks and capture Russian Karelia.

Late in 1918, Finnish politician Rudolf Holsti appealed for relief to Herbert Hoover, the American chairman of the Committee for Relief in Belgium. Hoover arranged for the delivery of food shipments and persuaded the Allies to relax their blockade of the Baltic Sea, which had obstructed food supplies to Finland, and to allow food into the country..
