Administrative / biographical background
Tyler entered the Navy in 1771 and was promoted to lieutenant in 1779. During the American War he served chiefly in the Channel and the Mediterranean and in the early part of the Revolutionary war in the Mediterranean. In 1799 he was appointed to the WARRIOR, at first in the Channel and after 1802 in the West Indies, and in 1805 to the TONNANT, with the Mediterranean fleet. He was severely wounded at Trafalgar. He was promoted to rear-admiral in 1808 and hoisted his flag as second-in-command at Portsmouth. Between 1812 and 1816 he was Commander-in-Chief at the Cape of Good Hope, after which he had no further service. He was promoted to vice-admiral in 1813 and to admiral in 1825. See W.H. Wyndham-Quin 'Sir Charles Tyler, G. C. B. Admiral of the White' (London, 1912).
