As acting
midshipman, he joined the
sloop of war , June 11, 1799, to cruise against French
privateers and warships in the
West Indies to August 1800. Appointed a
midshipman on August 20, 1800 (warrant subsequently altered to take rank from date of his original entry, June 11, 1799). After the war, was one of the midshipmen retained in the Navy under the Peace Establishment Act, signed by President Adams in one of his last official acts, on March 3, 1801. On close of the Quasi-War with France, he resumed nautical studies, then had blockade duty off
Tripoli in and . On October 13, 1803, he fell prisoner upon capture of
Philadelphia, commanded by
William Bainbridge, when the vessel ran aground on an uncharted reef off the coast of Tripoli, and remained a captive of the Barbary pirates until the American victory over Tripoli in 1805. Upon returning home, he spent much of his following years on a posting to the
New Orleans station (US Navy), where he took command after the outbreak of the War of 1812. He was promoted to Lieutenant in 1807. On March 21, 1808, he was ordered to report to the New Orleans station, under the command of Captain
David Porter. He was in semi-independent command of a flotilla of gunboats based in
Natchez, Mississippi from about January 1810 to February 1811. On July 24, 1813, Patterson was promoted from Lieutenant to
Master Commandant. On October 18, 1813, he was given command of the Naval Station at New Orleans. On September 16, 1814, Patterson raided the base of the pirate
Jean Laffite at
Barataria Bay, in cooperation with Colonel
George T. Ross, capturing six
schooners and other small craft. In that same month, he refused
Andrew Jackson's request to send his few naval units to
Mobile Bay where Patterson knew they would be bottled up by a superior
Royal Navy fleet. Patterson's naval assets were limited to six gunboats, a schooner, a sloop, as well as the
USS Carolina (1812) and
USS Louisiana (1812). Foreseeing British designs against New Orleans almost two months before their attack, Patterson, not Jackson, was the first to prepare to defend the city. On November 18, he outlined his plans to use the Louisiana, in concert with shore batteries, in a letter to the Secretary of the Navy. The American victory at the Battle of New Orleans resulted as much from his foresight and preparations as from Jackson's able fighting. His flotilla delayed the British advance at the
Battle of Lake Borgne until reinforcements arrived, then gave
artillery support in defense of the fortifications on the right bank of the
Mississippi River, from fortifications or craft borne in the Mississippi. Patterson, highly commended by Jackson, received a note of thanks from
Congress, and was promoted to Captain on February 28, 1815. Patterson remained on the southern stations until 1824. Because of failing health,
Thomas Macdonough relinquished command of whereupon Patterson then assumed command and became fleet captain and commander of this
flagship in Commodore
John Rodgers'
Mediterranean Squadron. Box' for Daniel T. Patterson, made by Jonathan Wilmarth, John L. Moffat, and Joseph Curtis, New York City, 1832 Returning home in 1828, he was appointed one of the three
Navy commissioners. He commanded the Mediterranean Squadron from 1832 to 1836. He then took command of the
Washington Navy Yard in 1836, an office he held until his death at
Wilmington, Delaware, August 25, 1839. Daniel Todd Patterson and his wife are buried in
Congressional Cemetery, Washington, D.C. ''The Life of Gould, an Ex-Man-of-War's Man,'' by Roland Gould (1867), noted on a website of the Navy Department Library at the Washington Navy Yard, purportedly contains a first-person account of the death of Commodore Patterson.
Rank Although Patterson is properly called a "
Commodore", during his years in the Navy this was not one of the hierarchical "line" ranks. Instead, "Commodore" applied to any officer in command of a fleet of two or more ships, regardless of the officer's "line" rank at the time, and regardless of whether the officer also held the dual role of commanding officer of one of the ships in the fleet. Thus Patterson was a Commodore at the time of the Battle of New Orleans because he commanded a fleet of ships, even though he was not promoted to the "line" rank of Captain until after the battle. He again became a Commodore when in command of the Mediterranean Squadron. Patterson was never an Admiral because in his day the highest "line" rank in the US Navy was Captain; the title Admiral was felt to smack of aristocracy and royalty, and did not become a "line" rank in the US Navy until the Civil War. ==Personal life==
