Shortly after 0100 local time on 8 July, 1987, SACEUR made perhaps the most critical pre-war decision for the Western alliance. As armies massing across Europe in the past days consumed the world’s attention, a debate had been raging inconspicuously in Brussels and select Western capitals. The question of whether or not to disperse NATO’s force of Pershing II and Ground Launched Cruise Missiles (GLCM) into the field was being discussed. From an operational standpoint, Galvin had been in favor of dispersing his primary tactical nuclear weapons immediately. The installations where the BGM-109G Gryphons, and Pershing IIs based would almost certainly be a prime target for Soviet airstrikes and commando raids once the balloon went up. The missiles would be more secure once deployed to their secret dispersal locations, spread out and under the watchful eye of well-trained Air Force security troops.
Politically, a decision to disperse had to be closely considered. Moving the force into the field could be mistaken as preparation for a pre-emptive strike by Moscow. If the Soviets really believed that, the war which everybody feared was about to begin would likely begin with nuclear weapons launched in the first salvo. Civilian reaction in NATO countries was another concern leaders had to take into account. Moving the weapons now could spark a panic if it became publicly known. This, in turn, could lead to unfounded rumors spreading, and a deeper public hysteria coming about at the worst possible moment.
When all was said and done, the decision was left up to the President of the United States and SACEUR. In a conversation shortly after midnight, Reagan let Galvin know that he was in favor of dispersal, but would leave the final decision up to his general. For Galvin, the decision was a no brainer. Intelligence indicated that the Soviets were moving their SS-20s out of garrison and into the field. So after the telephone call with Reagan ended, SACEUR called the secretary general and informed Carington of his intent to immediately order the dispersal of NATO’s ground based nuclear forces.
Before first light, at various sites across West Germany, United Kingdom, Belgium, and Italy, convoys slipped through the main gates and into the predawn darkness bound for their respective dispersal areas. At the Ground Launched Cruise Missile bases, the peace camps that European civilians had constructed in close proximity to the fences had been deconstructed and removed as tensions grew. One of these bases was RAF Greenham Common, home of the 501st Tactical Missile Wing.
The first vehicles to depart Greenham were the transport-erector launchers and accompanying security and maintenance vehicles belonging to Alpha Flight. Sixteen vehicles in total, the flight headed north towards its intended dispersal area ensconced in the North Wessex Downs. British military policemen stood guard along the route, keeping the few civilians who’s curiosity got the best of them from getting too close. Even before Alpha arrived at its intended destination, Charlie Flight was leaving the base for its own dispersal area.
Word of the GLCM and Pershing movement eventually made it east that afternoon, causing Soviet planners to make some last-minute revisions in their operational planning. Spetznaz commandos and intelligence officers who were on the ground near the NATO bases went into high gear attempting to locate the dispersal areas so that they could be raided the coming morning by nearby commando teams in hiding. These teams had penetrated into Western Europe days earlier, originally tasked with raiding the installations, which now seemed pointless given that most of them were empty. The race was now on to locate the dispersal sites and prepare the commando teams before the start of hostilities in less than 24 hours.
