 Almost immediately after the Soviet withdrawal the mujahideen attacked the eastern city of Jalalabad in a plan instigated by Hamid Gul of Pakistan's Inter-Service Intelligence (ISI).Both the Americans and Pakistanis expected for Jalalabad to rapidly fall to the guerillas and lead to a final victorious attack in Kabul.The Afghan Army proved their capability without Soviet troops as they managed to restrain the mujahideen attack, resulting in a major defeat for the mujahideen.
