After the war, military intelligence was once again fused into one organisation, GRU General Staff, which independently carried out strategic intelligence and directed operational and tactical intelligence. At this time the Party and Stalin took care to weaken the Army and the Ministry of State Security, both of which had strengthened their positions during the war to such an extent that they had stopped acknowledging the civil leadership, i.e. the party. The leading commanders, headed by Zhukov, were dismissed from the Army and Beria was also deprived of the leadership of the Tchekists. It would obviously not be a simple matter to expel him, so Stalin technically promoted him, appointing his deputy to succeed him, but in fact this deprived him of direct leadership of the Organs of State because his title of minister was taken away. Within the framework of the programme for weakening the Army and the Ministry of State Security, Stalin decided to remove intelligence from both the Army and State Security. This plan was put into effect in 1947. The GRU and the organs of political intelligence of the Ministry of State Security were joined together in one organisation called the KI: the Committee of Information. The man closest to Stalin was appointed to lead this organisation, and this was the activist of the Politburo, Molotov. Thus the Army and Ministry of State Security were deprived of intelligence. All intelligence work would henceforth be subordinate to the Party. Such a situation did not suit the Army or the Ministry of State Security, and they for the first time united against the Party.
From its inception the Committee of Information was an utterly ineffective organisation. The intelligence officers of the Ministry of State Security and the GRU, who formed the nucleus of the Committee of Information, strove by all means to return from under the control of the Party back to their own former organisations. Both sets of officers strove to sabotage the activities of the Committee of Information. The Ministry of State Security and the Army, acting in collusion, informed the Central Committee that they could no longer work effectively since they were receiving their information at second hand. Then they exerted pressure on their former officers in order to try to make the Committee of Information collapse from inside. The Central Committee of the Party made efforts to improve the effectiveness of the Committee of Information. In less than a year four chiefs were appointed and dismissed, for the reason that not one of them was able to counter the unified strength of the Ministry of State Security and the Army. After long struggles behind the scenes Abakumov, a pupil and favourite of Beria, became Chief of the Committee of Information.
At a stroke, all the intelligence services passed to the control of the Ministry of State Security. Stalin immediately saw that a mistake had been made. In his opinion, the creation of one intelligence service, even if it was under the leadership of the Party, must sooner or later lead to the Tchekists seizing power over this organisation, and this would mortally endanger the Party. There was only one way out of such a situation: immediately to liquidate the Committee of Information and divide the intelligence service into two hostile camps - military intelligence to the Army, and political intelligence to State Security. But the coup was not an easy one. To get round the problem, the Party naturally found support from the Army which had not been at all happy with State Security's monopoly of the intelligence service. On the instructions of Stalin, the first deputy of the chief of the general staff, General Shtemyenko, made a report to the Politburo on the subject of the 'blind general staff, after which the GRU was removed from the control of Abakumov and given to the Army. For his distinguished services, Stalin immediately appointed General Shtemyenko as chief of the general staff the senior curator of the GRU. After two years Shtemyenko and the GRU, seeking to please Stalin, presented documents about the existence of an agreement among subordinates of Abakumov. Abakumov was immediately shot, the Committee of Information finally abolished, and the usual purge carried out in the ranks of State Security.
But the Ministry of State Security did not forgive the general staff and the GRU for having taken such liberties. 1952 was a year of struggle between the Politburo and Stalin. The Ministry of State Security presented documents which they claimed proved the existence of a plot in the ranks of the GRU. This time it was the turn of the GRU and all the general staff to be purged. Stalin was opposed to the move, but the Politburo insisted. Shtemyenko was demoted to Lt-General and expelled from the general staff. The action continued against the general staff and the GRU, and even against Stalin himself who was removed as general secretary of the Communist Party later that year.
At the beginning of 1953, immediately after the death of Stalin, there ensued a fierce squabble among his disciples and comrades at arms for the distribution of the inheritance. The most dangerous pretender to the throne was, of course, Beria. The united strength of Army and Party was automatically against him. Beria was arrested at a joint session of Party and Army leaders and immediately done away with. After this there began the usual persecution of the Organs of State. During secret trials, incriminating documents were produced from the GRU concerning the leaders of the Ministry of State Security and many of its leaders were shot after frightful torture. The torture was carried out in the GRU cellars on Gogol Boulevard. At the beginning of 1954 the Ministry of State Security lost its status as a ministry and was transformed into a committee.
Simultaneously with the fall of the Ministry of State Security, the Army acquired more and more weight within the framework of the State. The 'Russian Bonaparte', Marshal Zhukov, became Minister of Defence, having returned from his exile under Stalin. After a short time Zhukov also became a member of the Politburo. He quickly effected the return of all the exiled generals and marshals and appointed them to key positions. The Ministry of State Security could not exercise any restraint on Zhukov and he was therefore able to appoint Shtemyenko to the post of Chief of the GRU, reinstating him as a full general after his demotion. The GRU became an organisation solely dependent on the Army. Zhukov's next step was a blow against Party influence in the Army. On his orders all political workers and Party commissars were expelled from the Army. He also ordered the Chief Political Directorate of the Soviet Army to stop interfering any more in Army affairs, and at the same time liquidated all the special departments of State Security present in the Army. The crocodile was clearly throwing off its bonds. In Politburo sessions Zhukov openly contradicted Khruschev and publicly abused him.
The party understood how rashly it had behaved in depriving the KGB of power, since the Party alone was clearly defenceless against the Army. There was absolutely no doubt that very soon the Army would become the only master of the situation. But in October 1957 Zhukov committed a grave error. He went on a visit to Yugoslavia and in his absence, a plenum of the Central Committee of the Party was hurriedly convened. Zhukov was secretly removed from the Politburo and also from his duties as Minister of Defence because of 'bonapartism'. The chief of the GRU, General Shtemyenko, learned about what had happened and immediately sent a telegram of warning to Zhukov in Yugoslavia, but it was intercepted by the KGB. Zhukov returned from Yugoslavia straight into renewed exile. Shtemyenko followed him, again reduced to the rank of lieutenant-general. (Some survive vicissitudes better than others: under Brezhnev, Shtemyenko was again reinstated.)
