Denmark Dumps the Nicobars, 1868

From The Rise and Fall of the Danish Empire, by Michael Bregnsbo and Kurt Villads Jensen (Palgrave Macmillan, 2022), Kindle p. 337:

Although Tranquebar and Serampore were sold in 1845, the colonial experience in Asia was not quite over. The Nicobar archipelago was not included in the sale. However, due to malaria, these islands were uninhabitable, and a last Danish colonization attempt was abandoned in 1848. Thereafter, there was no Danish connection with these islands. The islands were subsequently used as bases for pirates: therefore the British envoy approached the Danish government in 1868 with a request that it, as the holder of sovereignty, would intervene against the pirates and restore law and order, or alternatively hand over the sovereignty to Great Britain. The Danish government astonished the British envoy by not demanding any payment at all for such a transfer. After 1864, Denmark was not willing to risk anything.
