On the Allied side, both Winston Churchill and Joseph Stalin saw Prague as a significant prize, the seizure of which could significantly influence the political makeup of postwar Czechoslovakia. On 1 May 1945, before Berlin was subdued, Stalin issued orders directing the 1st Belorussian Front to relieve the 1st Ukrainian Front in the Berlin area so that the latter could regroup to the south along the Mulde River and drive on Prague. The 2nd Ukrainian Front also received orders on 2 May to drive on Prague from the southeast. Stalin was determined to have the Soviet Army present in force in western Czechoslovakia when the German troops there finally surrendered.
