Not much contact was ever made with the Andaman Islands, at the time known as the Nicobar Islands, before the Bengal government tried to establish a naval base on Chatham island. The people of the island weren't receptive to the visitors and attempted to fight off the intruders. The Bengal government was able to officially establish the base, but with little success. The British weren't originally planning to construct a colony in the Andamans due to a predated notion that the people were "savages." This prejudice is one of the leading causes of the heightened aggression between the British and Andamanese people.
In "Developing Terra Nullius: Colonialism, Nationalism, and Indigeneity in the Andaman Islands," Uditi Sen explores a more in-depth view of the relationship between the British and the Andamanese people. While stories of the island perverted the minds of the British before the ultimate colonizing of the island, any hope of peace between the British and Andamanese was thrown out the window. The British used technology far advanced compared to the Andamanese, but the islanders didn't give up quietly. There were wars fought and many British killed over their intrusion of the island.
