(India) (NH1) from Srinagar to Leh, are only two lanes. The rough terrain and narrow roads slowed down traffic, and the high altitude, which affected the ability of aircraft to carry loads, made control of NH 1 (the actual stretch of the highway which was under Pakistani fire) a priority for India. From their 130+ covertly occupied observation posts, the Pakistani forces had a clear line-of-sight to lay down indirect artillery fire on NH 1, inflicting heavy casualties on the Indians. This was a serious problem for the Indian Army as the highway was the main logistical and supply route. The Pakistani shelling of the arterial road threatened to cut Leh off, though an alternative (and longer) road to Leh existed via Himachal Pradesh, the Leh–Manali Highway. The infiltrators, apart from being equipped with small arms and grenade launchers, were also armed with mortars, artillery and anti-aircraft guns. Many posts were also heavily mined, with India later stating to have recovered more than 8,000 anti-personnel mines according to an ICBL report. Pakistan's reconnaissance was done through unmanned aerial vehicles and AN/TPQ-36 Firefinder radars supplied by the US. The initial Indian attacks were aimed at controlling the hills overlooking NH 1, with high priority being given to the stretches of the highway near the town of Kargil. The majority of posts along the LOC were adjacent to the highway, and therefore the recapture of nearly every infiltrated post increased both the territorial gains and the security of the highway. The protection of this route and the recapture of the forward posts were thus ongoing objectives throughout the war. The Indian Army's first priority was to recapture peaks that were in the immediate vicinity of NH 1. This resulted in Indian troops first targeting the Tiger Hill and Tololing complex in Dras, which dominated the Srinagar-Leh route. This was soon followed by the Batalik-Turtok sub-sector which provided access to Siachen Glacier. Some of the peaks that were of vital strategic importance to the Pakistani defensive troops were Point 4590 and Point 5353. While 4590 was the nearest point that had a view of NH 1, point 5353 was the highest feature in the Dras sector, allowing the Pakistani troops to observe NH 1. The recapture of Point 4590 by Indian troops on 14 June was significant, notwithstanding the fact that it resulted in the Indian Army suffering the most casualties in a
