evidence: In the days that followed, the Indian Army built up a large force to defend the 80 kilometre-long Saltoro Range ridgeline. Since then, the Saltoro Range has been the focal point of operations — the Pakistanis seeking to gain a foothold on the ridge line, the Indians denying it. In early April 1987, another attempt was made by the Pakistan Army to gain a foothold on the Saltoro ridgeline. A small force consisting of about a dozen SSG commandos, using ropes and ladders, went up a vertical cliff and occupied a position at over 21,000 ft that dominated the Indian positions at Bilafond La. They named it Quaid post. The Indian Army made several attempts to evict the commandos but each time they were repulsed with heavy casualties. On June 25, 1987, they succeeded in taking the post as the commandos had run out of ammunition and could not be resupplied as the base supporting them came under fire. With the only foothold on the ridgeline lost, the Pakistan Army launched a major attack in September 1987 to get to Bilafond La. The attack was repulsed. In March 1989, another attempt was made, this time in the Chumik glacier, three kilometres east of Giari (recently hit by an avalanche). At over 19,000 ft, the place chosen is the most difficult to scale in the Saltoro Range for either side.
