The Spring offensive of the White Army was an offensive mounted by the White Army in the Ural and Volga regions of Russia from March to April 1919 during the Russian Civil War.
At the end of December 1918, the White Army captured Perm, but the Red Army concurrently captured Ufa to the south, and, on 24 January, the Reds captured Uralsk. At the beginning of 1919, the Whites decided on a counterattack to the north (towards Petrograd) and the south (to crush the Red front on the Volga River and advance on Moscow). Both sides had around 110,000 troops deployed to the Eastern Front of the Civil War. The Siberian Army began its advance on 4 March and took Okhansk and Osa on 8 March and Sarapul on 10 April, and the Soviet 5th Army was crushed after four days of fighting and forced to retreat to Simbirsk and Samara. On 16 March, the Whites captured the major city of Ufa. Sterlitamak fell on 6 April, Belebek on 7 April, and Bugulma on 10 April, and, to the south, the Cossacks conquered Orsk on 9 April and advanced on Orenburg. The Red general Mikhail Frunze decided to halt his advance in eastern Russia and instead await reinforcements, halting the White advance on the southern flank as he prepared a counteroffensive. On 22 April, Frunze launched his Eastern Front counteroffensive against the over-extended Whites.
