In late May 1945 Josef Stalin ordered Marshall Georgy Zhukov to leave Germany and come to Moscow. He was concerned over the actions of British allies. Stalin said the Soviet forces disarmed Germans and sent them to prisoners’ camps while British did not. Instead they cooperated with Germans troops and let them maintain combat capability. Stalin believed that there were plans to use them later. He emphasized that it was an outright violation of inter-government agreement that said the forces surrendered were to be immediately disbanded. The Soviet intelligence got the text of secret telegram sent by Winston Churchill to Field Marshall Bernard Montgomery, the commander of British forces. It instructed to collect the weapons and keep them in readiness to give back to Germans in case the Soviet offensive continued.
According to the instructions received from Stalin, Zhukov harshly condemned these activities speaking at the Allied Control Council (the Soviet Union, the United States, the United Kingdom and France). He said the world history knew few examples of such treachery and refusal to observe the commitments on the part of nations that had an allied status. Montgomery denied the accusation. A few years later he admitted that he received such an instruction and carried it out. He had to comply with the order as a soldier.
A fierce battle was raging in the vicinity of Berlin. At his time Winston Churchill said that the Soviet Russia became a deadly threat to the free world. The British Prime Minister wanted a new front created in the east to stop the Soviet offensive as soon as possible. Churchill was overwhelmed by the feeling that with Nazi Germany defeated a new threat emerged posed by the Soviet Union.
Not later than April 1945 Churchill instructed the British Armed Forces’ Joint Planning Staff to draw up Operation Unthinkable, a code name of two related plans of a conflict between the Western allies and the Soviet Union. The generals were asked to devise means to “impose upon Russia the will of the United States and the British Empire”. The hypothetical date for the start of the Allied invasion of Soviet-held Europe was scheduled for 1 July 1945. In the final days of the war against the Hitler’s Germany London started preparations to strike the Soviet Union from behind.
