In August of the previous year, an expedition under Sir David Baird sailed against the Cape of Good Hope, to which were attached one sergeant, two corporals, and seventeen artificers of the Plymouth company under Captain J. C. Smith of the royal engineers, who embarked on board the ‘Melantho’ transport. The artificers landed on the 4th January, 1806, with the artillery, and marched and encamped with them in the field; but Sir David Baird, conceiving that their services would be more beneficial in the castle after its capture, than in action, would not permit them to take part in the operations. They therefore halted about a quarter of a mile to the right rear of the position, and there remained until they marched with the troops into the castle. Ever since this capture, a detachment of the corps of varying strength has been employed in the colony, not only at Cape Town, but at many posts and forts at a considerable distance inland and upon the frontiers. Two privates of the Cape detachment under Captain Kennett, of the corps, sailed in April with the force under General Beresford against Buenos Ayres. Landing at Point de Quilmes on the 25th June,[139] they were present at the surrender of the city on the 27th following. After a time the Spaniards, recovering from the panic which lost them their capital, retook it with signal success, and those of the British not killed, were taken prisoners. Captain Kennett was among the former, and one of the artificers was wounded. On the loss of their captain, the two men were attached to the artillery and served in the action of the 12th August, 1806, under Captain Alexander Macdonald, royal artillery: they subsequently were taken prisoners and remained so until January 1808, when they returned to England with the forces under General Whitelocke. ----- Footnote 139: ‘London Gazette Extraordinary,’ September 13, 1806. ----- To supply the casualties at Gibraltar occasioned by the fatal fever of 1804, a detachment of 133 artificers,[140] under Captain H. Evatt, royal engineers, embarked on the 31st December, 1805, and landed at the fortress in February following. The strength of the companies was thus increased from 174 to 307 of all ranks. ----- Footnote 140: With fifty women and forty children!
