beach and another five in two canoes, who retreated into the forest. The party progressed some miles into the island without facing any hostile response and saw a few huts with slanted roofs. Eventually, failing to find anyone, Bonnington and his men left the island. Notably, the Sentinelese were counted as a standalone group for the first time in the 1911 census. In 1954, Italian explorer Lidio Cipriani visited the island but did not encounter any inhabitants. T. N. Pandit (1967–1991) In 1967, a group of 20 people, comprising the governor, armed forces and naval personnel, were led by T. N. Pandit, an Indian anthropologist working for the Anthropological Survey of India, to North Sentinel Island to explore it and befriend the Sentinelese. This was the first visit to the island by a professional anthropologist. Through binoculars, the group saw several clusters of Sentinelese along the coastline, who retreated into the forest as the team advanced. The team followed their footprints and after about , found a group of 18 lean-to huts made from grass and leaves that showed signs of recent occupation as evidenced by the still-burning fires at the corners of the hut. The team also discovered raw honey, skeletal remains of pigs, wild fruits, an adze, a multi-pronged wooden spear, bows, arrows, cane baskets, fishing nets, bamboo pots and wooden buckets. Metal-working was evident. The team failed to establish any contact and withdrew after leaving gifts. The government was aware that leaving the Sentinelese (and the area) completely isolated and ceasing to claim any control would lead to rampant illegal exploitation of the natural resources by the numerous mercenary outlaws who took refuge in those regions, and probably contribute to the Sentinelese's extinction. Accordingly, in 1970, an official surveying party landed at an isolated spot on the island and erected a stone tablet, atop a disused native hearth, that declared the island part of India. In early 1974, a National Geographic film crew went to the island with a team of anthropologists (including Pandit), accompanied by armed police, to film a documentary, Man in Search of Man. They planned to spread the operation of gift-giving over three days and attempt to establish friendly contact. When the motorboat broke through the barrier reefs, the locals emerged from the jungle and shot arrows at it. The crew landed at a safe point on the coast and left gifts in
