for all Asian crewmen, but after 1661 and the ceding of Bombay to England by Portugal, the term was used mainly to describe crewmen from East India. Among other terms was "topaze" to describe Indo-Portuguese naval militia, especially from Bombay, Thana, and former Portuguese territories such as Diu, Dammam, Cochin and the Hugli River. The term "sepoy" was used to describe Indian military militia. The number of Indian seamen employed on UK ships was so great that the British tried to restrict this by the Navigation Acts in force from 1660, which required that 75 percent of the crew of a British-registered ship importing goods from Asia had to be British. Initially, the need arose because of the high sickness and death rates of European sailors on India-bound ships, and their frequent desertions in India, which left ships short of crew for the return voyage. Another reason was war when conscription of British sailors by the Royal Navy was particularly heavy from Company ships in India. Eighteenth century In 1756, a fleet under admirals Pocock and Watson, with an expeditionary force under Lieutenant-Colonel Robert Clive set off from Bombay with 1,300 men, including 700 Europeans, 300 sepoys and 300 'topaze Indo-Portuguese'. The expedition against Angria is one of the first references to the British use of Indo-Portuguese militia and one of the first actions of the Bombay Marine. Lascars served with The Duke of Wellington on campaign in India during the late 18th and early 19th century in India. In 1786, the Committee for the Relief of the Black Poor was originally set up thanks to concern over lascars left in London. However, in a report made after one month of the Committee's existence, it was found that only 35 of the 250 recipients of aid were lascars. On Captain James Cook's ill-fated second voyage to the Pacific, , had lost so many men (including Cook) that she had to take on new crew in Asia to get back to England. In 1797 one group of Lascars was shipwrecked off the coast off Tasmania on Preservation Island on a ship built in Calcutta. The Sydney Cove wreck was the first merchant wreck after the creation of the New South Wales colony. Lascars were paid only 50% of their fellow white sailors' wages and were often expected to work longer hours as well as being given food of often inferior quality
