Rear Admiral Sir Edward Thomas Troubridge, 2nd Baronet, CB, DL (c. 1787 – 7 October 1852) was an officer of the British Royal Navy who served in the French Revolutionary, Napoleonic and War of 1812. He later served for fifteen years as the member of parliament for Sandwich, Kent.
Troubridge entered the Navy on 21 January 1797 as a volunteer on board the ship Cambridge, the guard ship at Plymouth under the command of Captain Richard Boger. He was discharged in April 1799, and in January 1801 joined the ship Achille, Captain George Murray, as a midshipman. He followed Murray into the Edgar, seeing action at the battle of Copenhagen on 2 April 1801, and subsequently into London, until transferred in May 1802 to Leander, Captain James Oughton, for a short time. In July 1803, he joined the Victory, flagship of Lord Nelson in the Mediterranean, and in August 1804, moved into the frigate Narcissus, Captain Ross Donnelly, serving until February 1805.
On 22 February 1806 he was promoted to lieutenant aboard the Blenheim, his father's flagship in the East Indies, and in March was appointed acting-commander of the 18-gun brig-sloop Harrier. On 4 July 1806 Harrier and the frigate Greyhound, Captain Charles Elphinstone, destroyed the Dutch East India Company brig Christian Elizabeth under the fort of Manado. Two days later, off the island of Tidore, the two ships captured the Dutch 12-gun Belgica. On 26 July they fought a Dutch squadron off Sulawesi, consisting of the 40-gun frigate Pallas, the 20-gun corvette William, and the armed Indiamen Vittoria and Batavia, both richly laden. Only the William escaped capture. His share of the prize money for the captures was £26,000. In a letter to John Markham at the Admiralty following the action his father commented: "Elphinstone says Tom in the Harrier behaved like a brave, good fellow; had he done otherwise I would with great composure put a pistol ball through his nob..." In August 1806 Troubridge was appointed acting-captain of the frigate Macassar (formerly the Dutch Pallas), moving to the Greyhound in October. His promotion to commander was confirmed on 5 September 1806, and to post-captain on 28 November 1807.
Sir Thomas Troubridge was superseded as commander-in-chief in the East Indies by Sir Edward Pellew, and appointed commander-in-chief at the Cape of Good Hope. At Madras his flagship Blenheim was inspected and found to be unfit for further service, being hogged and taking on water even when at anchor. Despite the protests of her captain, Austin Bissell, Troubridge insisted on taking her to the Cape. Blenheim sailed on 12 January 1807, in company with the frigate Java, Captain George Pigot, and the sloop Harrier. On 5 February Harrier lost contact with the other ships near the island of Rodrigues. They were never seen again. Pellew ordered Troubridge in Greyhound to search for the missing ships. Starting at Rodrigues, he retraced their course to the Île de France, sending an officer ashore under a flag of truce to gain information. The French authorities informed him that the ships had been sighted at some distance off the Île Bourbon. At Île Sainte-Marie off Madagascar they learned that the ships had put into the harbour to take on water and fresh meat, before sailing for the Cape. There being no further sightings it was assumed that the ships had foundered during a storm. On the death of his father, Troubridge succeeded to the baronetcy. He was invalided home in January 1808.
On 5 February 1813 Troubridge was appointed to the 38-gun frigate Armide, for service in the War of 1812 against the United States. Armide, in company with Endymion, captured the 17-gun American privateer Herald on 15 August 1814, and the next day Armide alone captured the French 16-gun letter of marque Invincible. During the operations against New Orleans in January 1815 Troubridge served as commander of the Naval Brigade, and was highly praised for his efforts. Armide was paid off in May 1815
