Bhutto's promise was soon broken. Pakistan began to help separatist Khalistanis in Punjab, and later the militants in Kashmir. All with the intention of taking revenge for the drubbing it got in Bangladesh. In May, 1999, soldiers of Pakistan's Northern Light Infantry infiltrated and occupied several key heights in Drass and Kargil, leading to the Kargil war.
During the war, both armies did not cross the Line of Control, but the Pakistani army continued to provide supplies to their troops dressed as militants. Indian troops fought bravely and reoccupied the heights, and after increasing pressure from the US, Pakistan was forced to withdraw its forces back across the LoC.
