How winning Battle of Tololing helped India in Kargil War

"The Battle of Tololing became the turning point of the Kargil War. From Dras it appears close, but the reality was completely different. We had to climb steep, barren slopes at an altitude of nearly 16,000 feet in temperatures of minus 15 to minus 20 degrees Celsius. There was no cover, while the enemy occupied fortified positions equipped with machine guns, rocket launchers, mortars and Stinger missiles."
