Once he reached Moscow, he did not receive the expected Soviet support for his plans for a popular uprising in India. The Soviets were navigating a complex geopolitical and strategic web and did not want to break any potential alliance with the Allies in case of an impending German invasion. The German ambassador in Moscow, Count von der Schulenberg, soon arranged for Bose to go to Berlin. He arrived at the beginning of April 1941, and he met with foreign minister Joachim von Ribbentrop and later Adolf Hitler. In Berlin, Bose set up the Free India Centre and Azad Hind Radio, which commenced broadcasting to Indians on shortwave frequencies, reaching tens of thousands of Indians who had the requisite receiver. Soon Bose's aim became to raise an army, which he imagined would march into India with German forces and trigger the downfall of the Raj.
