Under Lenin, everything changed. He began by closing all the frontiers. Before the First World War more than 300,000 people went to Germany alone, each year, for seasonal work. Vladimir Ilyich soon put a stop to that. And having closed the country's frontiers he soon became aware that it would be no bad thing to shut himself away from the people behind a stone wall. He suddenly thought of the Kremlin. Lenin realised quite clearly that he would be shot at more often than the Emperors of Russia had ever been and without a moment's hesitation he abandoned the wide windows of the imperial palaces for the blank walls of the Kremlin.
Having shut his people in behind a wall of iron and having put a stone one between them and himself, Lenin then took a precaution which had not been resorted to in Russia for a thousand years. He brought in foreign mercenaries to guard the Kremlin-the 4th Latvian rifles to be precise. Lenin did not trust Russians with this job-he must have had his reasons.
These mercenaries claimed, as one man, that they were guarding Lenin out of purely ideological motives, since they were convinced socialists. Despite this, however, not one of them would acknowledge the validity of Soviet bank notes; they demanded that Lenin should pay them in the Tsar's gold. Thanks to Lenin, there was enough of this available. At the same time, a brave preacher in Riga prophesied that the whole of free Latvia would one day pay with its blood for these handfuls of gold.
The Kremlin also had a great appeal for Stalin, who inherited it from Lenin. He strengthened and modernised all its buildings thoroughly. Among the first of the changes he was responsible for was a series of large-scale underground constructions-a secret corridor leading to the Metro, an underground exit on to Red Square and an underground command post and communications centre. Stalin threw Lenin's foreign mercenaries out of the Kremlin. Many of them were executed straight away, others many years later-before the seizure of Latvia itself.
Stalin chose to spend a large proportion of his thirty years in power immured in the Kremlin. He also arranged for a number of underground fortresses to be built in the grounds of his various dachas in the country round Moscow. The most substantial of these was at Kuntsevo. His complex pattern of movement between the Kremlin and these dacha fortresses enabled Stalin to confuse even those closest to him about where he was at any particular moment.
Stalin's system of governing the country and of controlling its armed services is still in operation today. In peacetime all the threads still lead back to the Kremlin and to the underground fortresses around Moscow. In wartime, control is exercised from the control post of the High Command, which, incidentally, was also built by Stalin.
It is quite impossible to acquire a plot of land in the centre of Moscow-even in a cemetery. This is not surprising if you visualise a city which contains seventy Ministries. For Moscow is not only the capital of the Soviet Union but also of the RSFSR (Russian Soviet Federal Socialist Republic), which means that it must house not only Soviet ministries but dozens of republican ones as well. Besides these Moscow houses the KGB, the General Staff, the Headquarters of the Moscow Military District, the Headquarters of the Moscow District Air Defence Forces, the Headquarters of the Warsaw Treaty Organisation, CMEA, more than one hundred embassies, twelve military academies, the Academy of Sciences, hundreds of committees (including the Central Committee), and of directorates (including the Chief Intelligence Directorate-GRU), editorial offices, libraries, communications centres, etc.
Each of these wishes to put up its buildings as close as possible to the centre of the city and to build accommodation for its thousands of bureaucrats as close to its main buildings as it can.
A fierce battle goes on for every square metre of ground in the centre of Moscow and only the Politburo can decide who should be given permission to build and who should be refused.
And yet, almost in the centre, a huge, apparently endless field lies fallow. This is Khodinka, or, as it is known today, the Central Airfield. If this field were built on there would be room for all the bureaucrats. Their glass skyscrapers would rise right along the Leningradskiy Prospekt, which runs into Gorky Street and leads straight to the Kremlin. Many people look enviously at Khodinka musing about ways of cutting small slices out of it-after all this `Central Airfield' is not used by aircraft: it simply lies there, empty and idle.
For several years the KGB made efforts to acquire a small piece of land at Khodinka. The Lubyanka could not be enlarged any further, but the KGB was still growing. A vast new building was needed. But all attempts by the KGB to persuade the Politburo to allocate it some land at Khodinka were unsuccessful. That was how the huge new KGB building came to be built right out beyond the ring-road-a highly inconvenient location. Meanwhile the endless field still stretches through the centre of Moscow, lying empty as it always has done. Once a year rehearsals for the Red Square military parade are held there and then the field sinks back into lethargy. Naturally this valuable piece of ground is not being kept just for these rehearsals. The troops could be trained on any other field-there are enough of them around Moscow.
Why does the Politburo refuse even the KGB, its favourite offspring, permission to cut the smallest corner off this vast unused field? Because the field is connected to the Kremlin by a direct underground Metro line-Sverdlov Square (under the Kremlin itself)-Mayakovskaya-Byelorusskaya-Dinamo-Aeroport. Muscovites know how often and how quickly this line is closed during any kind of holiday or celebration, or any other event which breaks the normal rhythm of life in the Soviet capital.
Why do the Soviet leaders particularly like this Metro line? Already before the war many spacious underground halls had been built for Moscow Metro stations and the ceremonies to mark the anniversary of the revolution, on 6 November, 1941, were actually held in the Mayakovskiy Metro station. Everyone invited to attend had to reach the station from above, because the line had been closed. Once they were there a special Metro train appeared carrying Stalin, Molotov and Beriya. They came from the Sverdlov Square Metro station. To reach this, they do not, of course, leave the Kremlin. They have their own secret corridor leading to the Metro from right inside its buildings.
Stalin's route out of the Kremlin has existed unchanged for several decades. If necessary, any or all of the members of the Politburo can be taken underground, in complete secrecy and security, to Khodinka, where government aircraft await them in well-guarded hangars. With normal organisation, the Politburo can leave the huge, traffic-laden city within fifteen minutes, during which no outsider will spot official cars speeding along streets in the centre or helicopters flying out of the Kremlin.
North-west of Moscow is another government airfield-Podlipki. (Incidentally, just beside this airfield is the centre at which cosmonauts are trained.) The sub-unit stationed at Podlipki is known as the 1st Task Force of the Civil Air Fleet. In fact it has virtually nothing to do with the Civil Air Fleet-it is a group of government aircraft. Ordinary official flights begin and end at Podlipki. Special official flights, involving ceremonial meetings and escorts, make the brief flight to Sheremetyevo or to one of Moscow's other large airports. In an emergency the Politburo could be evacuated in various ways:
