In 1965, the third Indian expedition, which was led by Mohan Singh Kohli and his deputy Colonel Narendra Bull Kumar, included 21 core members of the expedition, and around 50 climbing sherpas. The mission was sponsored by the Indian Mountaineering foundation. The team started their journey from New Delhi on 21 February and reached on Jaynagar railway station in Bihar, the Indo-Nepal border on 24 February. They arranged for 25 tons of materials for the mission from various cities of India, including food, cloths, sleeping tents, oxygen cylinders and mountaineering equipment. All materials were carried from Jaynagar railway station to base camp by 800 porters including women. The initial attempt was attempted at the end of April and due to bad weather they came back to base camp and wait two weeks for better weather. Towards the end of May, Mount Everest was scaled in four successive attempts and put nine climbers on to the summit, setting a world record which India held for 17 years.
