India regained control of the hills overlooking NH 1D, the Indian Army turned to driving the invading force back across the Line of Control. The Battle of Tololing, among other assaults, slowly tilted the combat in India’s favour. The Pakistani troops at Tololing were aided by Pakistani fighters from Kashmir. Some of the posts put up a stiff resistance, including Tiger Hill (Point 5140) that fell only later in the war. Indian troops found well-entrenched Pakistani soldiers at Tiger Hill, and both sides suffered heavy casualties. After a final assault on the peak in which 10 Pakistani soldiers and 5 Indian soldiers were killed, Tiger Hill finally fell. A few of the assaults occurred atop hitherto unheard of peaks – most of them unnamed with only Point numbers to differentiate them – which witnessed fierce hand to hand combat.   As the operation was fully underway, about 250 artillery guns were brought in to clear the infiltrators in the posts that were in the line-of-sight. The Bofors FH-77B field howitzer played a vital role, with Indian gunners making maximum use of the terrain that assisted such an attack. However, its success was limited elsewhere due to the lack of space and depth to deploy the Bofors gun.   It was in this type of terrain that aerial attacks were used with limited effectiveness. French made Mirage 2000H of the IAF were tasked to drop laser-guided bombs to destroy well-entrenched positions of the Pakistani forces. However, The IAF lost a MiG-27 strike aircraftwhich it attributed to an engine failure as well as a MiG-21 fighter which was shot down by Pakistan; initially Pakistan said it shot down both jets after they crossed into its territory. One Mi-8 helicopter was also lost, due to Stinger SAMs.

On 27 May 1999, Flt. Lt. Nachiketa developed engine trouble in the Batalik sector and bailed out of his craft. Sqn Ldr Ajay Ahuja went out of his way to locate his comrade but was shot down by a shoulder-fired Stinger missile. According to reports, he had bailed out of his stricken plane safely but was apparently killed by his captors as his body was returned riddled with bullet wounds.   In many vital points, neither artillery nor air power could dislodge the outposts manned by the Pakistani soldiers, who were out of visible range. The Indian Army mounted some direct frontal ground assaults which were slow and took a heavy toll given the steep ascent that had to be made on peaks as high as 18,000 feet (5,500 m). Since any daylight attack would be suicidal, all the advances had to be made under the cover of darkness, escalating the risk of freezing. Accounting for the wind chill factor, the temperatures were often as low as −15 °C to −11 °C (12 °F to 5 °F) near the mountain tops. Based on military tactics, much of the costly frontal assaults by the Indians could have been avoided if the Indian Military had chosen to blockade the supply route of the opposing force, virtually creating a siege. Such a move would have involved the Indian troops crossing the LoC as well as initiating aerial attacks on Pakistan soil, a manoeuvre India was not willing to exercise fearing an expansion of the theatre of war and reducing international support for its cause.   Two months into the conflict, Indian troops had slowly retaken most of the ridges that were encroached by the infiltrators; according to official count, an estimated 75%–80% of the intruded area and nearly all high ground were back under Indian control.

Withdrawal and final battles

Following the outbreak of armed fighting, Pakistan sought American help in de-escalating the conflict. Bruce Riedel, who was then an aide to President Bill Clinton, reported that US intelligence had imaged Pakistani movements of nuclear weapons to forward deployments for fear of the Kargil hostilities escalating into a wider conflict. However, President Clinton refused to intervene until Pakistan had removed all forces from the Indian side of the Line of Control. Following the Washington accord of 4 July 1999, when Sharif agreed to withdraw Pakistani troops, most of the fighting came to a gradual halt, but some Pakistani forces remained in positions on the Indian side of the LOC. In addition, theUnited Jihad Council (an umbrella for extremist groups) rejected Pakistan’s plan for a climb-down, instead deciding to fight on.   The Indian army launched its final attacks in the last week of July; as soon as the Drass subsector had been cleared of Pakistani forces, the fighting ceased on 26 July. The day has since been marked as Kargil Vijay Diwas (Kargil Victory Day) in India. By the end of the war, Pakistan had to withdraw under international pressure and due to pressure from continued fighting at battle front and left India in control of all territory south and east of the Line of Control, as was established in July 1972 as per the Simla Agreement.
