Robert Mann (Royal Navy officer)

Robert Mann (c.1748 – 20 September 1813) was an officer of the Royal Navy. He served during the American War of Independence and the French Revolutionary Wars, eventually rising to the rank of admiral of the red.

Mann was born into a naval family. His father, the elder Robert Mann, was a captain in the navy. He was mortally wounded while commanding HMS Milford (1759) during the capture of the French privateer Gloire on 7 March 1762, during the Seven Years' War. His son, the younger Robert Mann, was born c. 1748. He embarked on a naval career and was commissioned as lieutenant on 26 May 1768.

American War of Independence
On 24 June 1776, during the American War of Independence, received a promotion to commander and given his first command, the 10-gun HMS Zephyr. Mann was promoted to post-captain on 30 May 1777 and appointed to command the 32-gun HMS Alarm (1758) in October that year, where he remained until April 1779.

Mann next assumed command of the 32-gun HMS Cerberus (1779) in July 1779. In 1780 Mann fell in with a Spanish fleet consisting of twelve sail of the line and several frigates under Don Joseph Solano. He followed the Spanish for several days, proceeding to give the earliest intelligence dispatches to Admiral Sir George Rodney, whom he found at anchor at Barbados. On 25 February 1781, whilst cruising twenty leagues off Cape Finisterre, he captured the Spanish 28-gun frigate Graña, under Don Nicolás de Medina. Graña was a month out of Ferrol but had not captured anything. In the action with Cerberus she lost her first lieutenant and six men killed, and seventeen wounded, out of her crew of 166 men. The Spanish officers fought as long as they could, but their men deserted them. Captain Mann in contrast was highly pleased with the behaviour of the officers and men of the Cerberus, in which only two were wounded. From October 1782 until the end of the war, he commanded the 64-gun HMS Scipio (1782).

Years of peace
From June 1787 to April 1791 Mann commanded the 74-gun HMS Bedford (1775).

French Revolutionary Wars
Mann returned to take command of the Bedford in January 1793, remaining there until late 1794. He was promoted to rear-admiral of the blue on 4 July 1794 and raised his flag aboard the 74-gun HMS Defence (1763). He soon transferred it to the 74-gun HMS Cumberland (1774) and sailed from Portsmouth on March 1795, passed the strait of Gibraltar and reinforced the Mediterranean Fleet under Admiral Sir William Hotham off the east coast of Minorca. Mann was promoted to rear-admiral of the white on 1 June 1795 and after cruising for a short time, the British anchored in St. Fiorenzo Bay on 29 June and refitted their ships. He transferred his flag to the 100-gun HMS Victory on 7 July and took part in the Battle of Hyères Islands on 13 July 1795. The Victory suffered considerable damage, having had her stays shot away, as well as much of the rigging. He transferred his flag to the 98-gun HMS Windsor Castle (1790) in December 1795. He was given command of a detached squadron in 1796 and sailed to Gibraltar with seven ships to watch the French fleet at anchor at Cadiz under Admiral Joseph de Richery.

He remained there for a month, before sailing to Toulon with supplies for Admiral Sir John Jervis's blockading fleet. With the Spanish entry to the war, a large Spanish fleet of twenty ships of the line as an escort for the French who planned to attack Newfoundland had already sailed. While returning to Gibraltar on 1 October Mann's squadron, accompanied by three transports and a brig, squadron sighted the Spanish fleet under Don Juan de Lángara in the south-east quarter. At 11 pm, helped by an easterly breeze, the Spanish bore up and captured the merchant brig and one of the transports, but Mann and his seven ships of the line managed to escape into Rosia Bay, near the mole of Gibraltar. Mann then held a conference with his captains, and decided not to return to the Mediterranean, but instead to sail north with a convoy, and then cruise off Cape Finisterre for a time. With his ships in poor condition after a long period at sea, Mann then returned to England to refit. Mann had no authority to make this decision, and it infuriated Jervis, who accused him of jeopardising the British strategy and forcing a temporarily withdrawal from the Mediterranean.

Mann was ordered to strike his flag and never again received an active command. He continued to be promoted according to his seniority, reaching vice-admiral of the white on 14 February 1799, vice-admiral of the red simultaneously with admiral of the blue on 23 April 1804, admiral of the white on 28 April 1808, and finally admiral of the red on 12 August 1812. He was appointed one of the Lords Commissioners of the Admiralty in 1798. He died on 20 September 1813.
