The initial phase of the operation began on the 19 November with an offensive carried out principally by Afghan troops, in order to clear the plains around Gardez, before moving into mountainous areas. By 28 November, they had cleared Ghalgai, Dara, and Saruti Kandau at the base of the Shabak Khel valley, while a flanking force made its way into the Kanai valley. On 30 November, a force of 900 Afghan commandos were airlifted into Shabak Khel valley. Heavy fighting also broke out in the neighbouring Kanai valley, where DRA troops advanced slowly but surely, building defensive outposts as they went, and suffering from punishing Mujahideen counter-attacks, that inflicted heavy losses.
Capture of the Satukandav Pass
The Satukandav Pass, 30 km east of Gardez, was the main passage between Kabul and Khost. Here the Mujahideen placed their main blocking position, concentrating their forces and digging in anti-aircraft guns and other heavy weapons. To defend the approaches of the Satukandav, the Mujahideen deployed ten BM-12multiple rocket launchers, and placed ZGU-1 anti-aircraft guns on every height. They had a plentiful supply of DShK machine guns, 75 and 82 mm recoilless rifles, and RPG-7anti-tank rocket launchers. They also mined the opening of the pass to a depth of three kilometers, boasting that their position was impregnable. Following the failure of the negotiations, an attack was launched on the 28 November. In order to discover the enemy positions, Soviet Colonel General Boris Gromov ordered that dummy paratroopers be dropped near the pass. When the Mujahideen opened fire, Soviet reconnaissance aircraft were able to pinpoint their positions and direct airstrikes against them. This was followed by a four-hour artillerybarrage. The first ground attack was carried out on the 29 November by a motorised rifle regiment. The attack quickly bogged down under heavy fire and Mujahideen counter-attacks, and the Soviet force withdrew after suffering severe casualties. On Gromov's orders, a new attack was launched on the 1 December this time with an Airborne Battalion and a battalion of Afghan Army commandos. These units succeeded in capturing the high ground above the pass. The Mujahideen, threatened with encirclement, beat a hasty retreat, abandoning most of their heavy weapons and equipment.
Relief of Khost
The Soviet forces then launched several airborne attacks, though they were limited in this by the Mujahideen use of Stinger missiles. In a night attack, an airborne brigade was flown in by helicopters to capture Mirujan, at the southern end of the mountains on the Gardez-Khost road. Simultaneously, another brigade was airlifted into Khost and staged a breakout to rejoin the main force. The Mujahideen, having lost control of the pass, realised that a conventional defence would only entail more losses for them, and they withdrew their main units from the path of the Soviet offensive. Beforehand, they laid mines on the road, and maintained a constant long-range fire with 107 mm rockets. They also sprang ambushes on Soviet units that ventured too far from the main force. In one such ambush, 24 Soviet paratroopers were killed. Despite this, the Soviet armoured columns made a slow but regular progress, entering Khost on the 30 December. Soviet and DRA outposts were maintained to keep the Gardez-Khost road open, but were withdrawn at the end of January.
Aftermath
Operation Magistral was a success for the Soviet army, but occurred too late in the war to have any lasting effect. When the main Soviet force had withdrawn, Mujahideen groups cut off Khost once again, as they had done since 1981. In April 1988, by signing the Geneva Accords the Soviet Union became committed to withdrawing its forces from Afghanistan.
