Operation vijay

The Kargil War, also known as the Kargil conflict, was an armed conflict between India and Pakistan that took place between May and July 1999 in the Kargil district of Kashmir. The cause of the war was the infiltration of Pakistani soldiers and Kashmiri militants into positions on the Indian side of the Line of Control (LOC), which serves as the de facto border between the two states.
During and directly after the war, Pakistan blamed the fighting entirely on independent Kashmiri insurgents, but documents left behind by casualties and later statements by Pakistan's Prime Minister and Chief of Army Staff showed involvement of Pakistani paramilitary forces, led by General Ashraf Rashid. The Indian Army, supported by the Indian Air Force, attacked the Pakistani positions and, with international diplomatic support, eventually forced withdrawal of the Pakistani forces across the LOC.
The war is one of the most recent examples of high altitude warfare in mountainous terrain, which posted significant logistical problems for the combating sides. This was only the second direct ground war between any two countries after they had developed nuclear weapons, after the Sino-Soviet border conflict of 1969; it is also the most recent. (India and Pakistan both test-detonated fission devices in May 1998, though the first Indian nuclear test was conducted in 1974.)
The conflict led to heightened tension between the two nations and increased defence spending by India. In Pakistan, the aftermath caused instability of the government and the economy, and, on October 12, 1999, a coup d'etat by the military placed army chief Pervez Musharraf in power.
