After a more protracted stay on the coast of Malabar, where he purchased from the Nabob, the celebrated Hyder Ali Khan, a number of plots of ground in the vicinity of Mangalore, Carwar, and Balliapatam, the very centre of the pepper trade, and erected a factory at an expense of 28,074 florins (£2800), this enterprising man set sail for the Coromandel Coast and the Bay of Bengal, and about the commencement of 1778 visited the Nicobar Islands, in order there also to found a factory. Unfortunately, of this visit there nowhere survive any detailed particulars, and the only document extant under Bolts' hand, which can throw any light on the subject, is a statement of the expenditure incurred in erecting a fort on the Nicobars, which, together with the purchase of a _goëlette_, and a snow, or two-masted vessel, for the coasting trade between Madras, Pegu, and the group of islands, amounted to 47,659 fl. 48 kr. (about £4760). At the close of 1780 Bolts returned to Europe, and in May, 1781, cast anchor in the harbour of Leghorn. His exertions and his speculation had not been attended with the success anticipated, and despite fresh assistance afforded by the Austrian Government to the Association, which at first seemed to promise a more auspicious future for the undertaking, yet the political complications of the period, and especially the sudden, totally unlooked-for rupture of peace between France, England, and Holland, ere long entailed utter ruin on the trading company, which, in the year 1785, found itself compelled to stop payment.[5] Bolts died at Paris in April, 1808, in utter destitution, and Michaud, in his _Biographie Universelle_, dedicated an article to this hardy and enterprising, rather than shrewd and prudent, adventurer.[6] About two years after the appearance of the Austrian ship in the Nicobar Archipelago, the Danes endeavoured to found there a missionary station of Moravian Brothers. Towards the close of 1778 the missionaries, Hänsel and Wangemann, sailed from Tranquebar to Nangkauri, where they arrived in January, 1779. In 1787 the mission at Nangkauri was once more abandoned, when the only surviving Moravian Brother returned to Tranquebar, and shortly after to Europe. In 1795 an Englishman, Major Symes, touched at Kar-Nicobar, while on his voyage as Envoy to Ava and Burmah. His observations there may be found in the second volume of "Asiatic Researches," p. 344, in an article entitled "Description of Carnicobar."
