 The 9th offensive was carried out in reprisal for the destruction of the DRA garrison at Peshgur, during which Massoud's mobile groups took 500 prisoners including 126 officers and killed a brigadier of the Afghan Army.The prisoners had been marched into the mountains, where the Mujahideen claimed they were killed by a Soviet aerial bombardment, a claim others dubbed suspicious.Initiated hours after the raid, the Soviet counter-attack installed a new garrison in Peshgur, and pursued the retreating Mujahideen.
