In the spring of 1918, besides the agent, aerial and other types of intelligence services, the diversionary intelligence service came into being. These diversionary detachments reported to the intelligence chiefs of fronts, armies, corps and sometimes divisions, and were called the 'cavalry of special assignments'. Formed from the best cavalrymen in the Army, they dressed in the uniform of the enemy and were used to carry out deep raids in the enemy's rear, to take prisoners - especially staff officers - to collect information on enemy positions and activities and to undermine and sometimes physically destroy the enemy's command structure. The number of these diversionary units and their numerical strength constantly increased. In 1920, on the Polish Front, on the staff of the Soviet forces, there was a separate cavalry brigade for 'special assignments' with a strength of more than two thousand cavalrymen, and this was on top of several regiments and separate squadrons. All these units were dressed in Polish uniform. Much later these diversionary units received the name Spetsnaz, now given to all special forces of the GRU.
From its inception, military intelligence suffered the greatest Possible antagonism from the Tchekists. The Tcheka had its own central agent network and an agent network in local areas. The Tchekists jealously guarded their right to have secret agents and could not resign themselves to the idea that anyone else was operating similar secret networks. The Tcheka also had units of 'special assignments' which carried out raids, not in the enemy's rear, but in its own rear, destroying those who were dissatisfied with the communist order.
During the civil war the Tcheka strove to unite all special assignment units under its own control. Several cases are recorded of the Tchekists trying to take over organs of military intelligence. One such attempt occurred on 10 July 1918 when the Tcheka shot the whole staff of the Eastern Front intelligence department, which had been in existence for only twenty-seven days, together with the entire staff of the front and the commander himself, M. A. Muravev, who had been trying to intervene in favour of his intelligence department. The whole of the agent system of military intelligence passed into the control of the Tchekists, but this brought the front to the very edge of catastrophe. The new commander, I. I. Vatsetis, and his chief of staff had no intelligence service of their own, and were unable to ask for the necessary information. They could only request information in a very tactful way, being well aware of the Tcheka's attitude to those it disliked. (As regards Vatsetis the Tchekists did indeed shoot him, but much later.)
Naturally while the agent network was under the control of the Tcheka, its own work was given priority, and any tasks set it by the Army Command were given very low priority. This of course brought the forces very near to complete defeat. If the army intelligence service is separated from the army staff, then the brain becomes nothing more than the brain of a blind and deaf man. Even if the blind man receives essential information from one source or another, his reaction will still be slow and his movements imprecise. The leader of the Red Army, Trotsky, placed an ultimatum before Lenin: either give me an independent military intelligence service or let Dzerzhinsky lead the Army with his Tchekists.
Lenin knew what the Tcheka was capable of but he also knew that its capabilities were extremely one-sided. He therefore ordered Dzerzhinsky not to interfere in matters of military intelligence. In spite of this, the Tcheka's attempts to swallow up military intelligence went on, and these efforts still continue on a reduced scale up to the present day.
Towards the end of 1918 the organisation of military intelligence from regimental staff level up to the level of front staff had been virtually completed. There remained only one staff which as deprived of its own intelligence service of the Republic, the staff of the Red Army (at that time called the Field Staff, later the General Staff). For this reason the general staff remained blind and deaf, obtaining information indispensable to its work at secondor third-hand. In addition to this, the absence of a superior intelligence organ meant a complete lack of co-ordination of the front intelligence services. Military intelligence had acquired a pyramid structure, but the top of the pyramid was missing. The Chief of the Army and in charge of all military production, Leon Trotsky several times approached Lenin with the demand that he should create such a superior military intelligence organ. Understanding the necessity for the creation of such an organ, but realising that this would inevitably mean a strengthening of the position of Trotsky, Lenin prevaricated and repeatedly refused Trotsky's suggestion. At the beginning of autumn, the position of the communists worsened sharply. Production, fuel and political crises became more acute. Armed uprisings were taking place against the communists. There was an attempt on the life of Lenin himself. In order to save the regime the communists decided on a desperate measure. In each town and village they would take hostages and, in the case of the slightest manifestation of discontent among the inhabitants, these hostages would be shot. The Soviet state was saved, by mass executions. Then another problem arose. The Tcheka, released from its restraints and drunk with blood, got out of control. In Tver and Torzhok the Tchekists, together with the hostages, destroyed communist leaders who displeased them. One threat to the stability of the state had been replaced by another, far worse. Lenin, not yet completely recovered, immediately resumed day-to-day leadership. Without restricting the terror, he took a number of steps to control it. The most important of his decisions were, firstly, to give to the People's Commissariats (i.e. the ministries), the provincial and town committees the right to take part in court cases against arrested communists. A communist would be declared not guilty if two members of the Party Committee testified in his favour. Secondly, Lenin directed his attention to the annulment of the Tcheka's monopoly of secret activity. He finally accepted Trotsky's proposal and on 21 October 1918 signed a decree, creating a superior organ of Soviet military intelligence which was to be called the Registrational Directorate of the Field Staff of the Republic.
