single battle during the conflict. Although most of the posts in the vicinity of the highway were cleared by mid-June, some parts of the highway near Drass witnessed sporadic shelling until the end of the war. Once India regained control of the hills overlooking NH 1, the Indian Army turned to driving the invading force back across the LOC. The Battle of Tololing, amongst 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 ten Pakistani soldiers and five 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. However, its success was limited elsewhere due to the lack of space and depth to deploy it. The Indian Air Force was tasked to act jointly with ground troops on 25 May. The code name assigned to their role was Operation Safed Sagar It was in this type of terrain that aerial attacks were used, initially with limited effectiveness. On 27 May 1999, the IAF lost a MiG-27 strike aircraft piloted by Flt. Lt. Nachiketa, which it attributed to an engine failure, and a MiG-21 fighter piloted by Sqn Ldr Ajay Ahuja which was shot down by the Pakistani army, both over Batalik sector.; initially Pakistan said it shot down both jets after they crossed into its territory. According to reports, Ahuja had bailed out of his stricken plane safely but was apparently killed by his captors as his body was returned riddled with bullet wounds. One Indian Mi-8 helicopter was also lost due to Stinger SAMs. French made Mirage 2000H of the IAF were tasked to drop laser-guided bombs to destroy well-entrenched positions of the Pakistani forces and flew its first sortie on 30 May.
