Then, to everybody’s consternation, Soviet and Allied radar warning receivers (RWR) detected the launch of a real salvo of SAM from one of the forward Soviet battalions near Dortmund. Defection from the attackers’ ranks promptly occurred as several Warsaw Pact pilots realized the implications of Soviet SAM firing into the middle of the melee in the air. As the salvo of SA-4 missiles was not repeated it is not known whether a trigger-happy major had been demonstrating a rare flash of initiative or whether a decision at a higher level had been hastily countermanded as a result of angry protest from the Warsaw Pact fighter commander.
In the B-52s each electronic warfare officer (EWO) sat in his compartment oblivious to the crackle of sound in his headset, intent only on the 12-inch-square cathode-ray tube in front of him which displayed the information from a suite of ECM equipment on either side. The SA-4 launch was monitored and when warning of missile ‘lock on’ was received the automatic self-jamming screen immediately broke the link. SA-4 homing frequencies had long been known and, to the EWO’s relief, they had not been changed. None of the bombers fell to SAM attack.
Combatants elsewhere in the sky were not so fortunate. Subsequently, several pilots from both sides vehemently claimed that they had been shot down by SAM rather than by enemy fighters. Certainly they were not expecting such interference from the ground, but in fact very few of the pilots knew for certain exactly what had shot them down. The MiGs were intent on reaching the bomber stream but could not afford to ignore the
The main air battle raged for little more than five minutes, but that was just long enough for almost all the bombers to complete their bombing runs. Below them, the units of the 20 Guards Army were completing their nightly replenishment before moving on to maintain the momentum of the advance against what must have seemed from its apparent attempt to disengage during the night a defeated II British Corps. The revving of tank and BTR engines, the rumble of fuel bowsers, engineer trucks and all the other noises of four divisions preparing to attack obscured completely the faint whine of jet engines 8 miles above. There was no warning as the first deluge of 500 lb bombs smashed down among them. In the next six minutes over 1,500 tons of high explosive thundered over an area of little more than 8 square miles. The T-72 and T-80 tanks that had survived frontal assaults from air-to-surface rockets were shattered by direct hits or had their tracks torn off by blast, while BTR and soft-skinned vehicles were destroyed in their hundreds. The impact on the Soviet ground troops was terrific. Many were killed outright or injured. Many more were stunned and paralysed. Tank and BTR crews were caught either on top of their vehicles or away from them on the ground. Most were reservists, having their first taste of battle, and many broke down under the surprise, ferocity and duration of this thunderous assault from an unseen enemy. Two forward divisional headquarters survived but 20 Guards Army in less than ten minutes of one-sided combat, had virtually ceased, for several vital hours, to exist as a fighting formation.
Inevitably, losses on the ground were not confined to 20 Guards Army. Although a bombing line 1,200 yards ahead of the defending British and Dutch troops had been defined, free-falling bombs from 40,000 feet are no respecters of bomb lines. And although the bombers’ approach on a track parallel to the bomb line had reduced the risk from shortfalls, the navigator bombardiers were not all equally adept at handling their almost fully-automated bombing systems. As a result, one British battalion and some companies of Dutch infantry suffered heavy losses.
