# Dover Castle (1798 EIC ship)

Dover Castle was launched in 1798 as an East Indiaman for the British East India Company (EIC). She made six voyages for the EIC. During the second she transported EIC troops to Macao to augment the Portuguese forces there, but the authorities there refused them permission to land. In 1814 Dover Castle was sold and she served for a half-dozen years as a London-based transport. She was hulked c.1820 and finally broken up in 1826.

Macao Expedition: During the French revolutionary and Napoleonic Wars the British Government and the EIC feared that the French would capture one or more of Portugal's colonies of Goa, Damam, Diu, or Macao and use it as a base for operations against Britain's possessions. Because Portugal was a British ally the British could not invade the colonies, it could only offer assistance in the form of extra troops. In 1801 the Admiralty asked Admiral Peter Rainier, the commander-in-chief of Royal Navy operations on the East Indies Station to assist the Portuguese at Macao.
Governor-General Warren Hastings decided to charter two East Indiamen, Dover Castle and Asia, to carry troops to Macao and offer the troops to the Portuguese as an augmentation of the garrison. A third vessel, the transport Rainier, would accompany the expedition.
The troops consisted of a company of the 78th Regiment of Foot, 500 men of the Bengal Marine Battalion, a company of European artillery, and a number of field and carriage guns, all under the command of Lieutenant-Colonel Hamilton. HMS Romney was to provide an escort as far as the straits of Macassar.
Dover Castle was at Saugor on 29 October. The expedition set out on 10 November. It stopped at Penang to exchange the Marine Battalion for soldiers there and at Malacca who would be better suited to the task at hand. Dover Castle was at Penang on 26 December. Lieutenant-Colonel Hamilton then had the expedition stop at Amboina to take on water so that there would be sufficient on hand if the troops could not land at Macao. Dover Castle was at Amboina on 5 February 1802, and the expedition sailed on 15 February; HMS Arrogant provided the escort.
The expedition arrived at Lintin Island on 18 March. The Governor of Macao refused on 24 March to give permission for the troops to land, absent orders from his superiors at Goa. Ultimately, permission was not forthcoming. Dover Castle was at "Sambroke" on 23 April, and Lintin again on 14 May. On 3 July Dover castle and Asia sailed from Macao to return to Bengal.
