Leonidas R. Smith (1829 – December 26, 1869) was an American steamboat captain and soldier. In the American Civil War he served the Confederate States of America as a volunteer; he was named Commander of the Texas Marine Department under General John B. Magruder. Smith was involved in most major conflicts along the Texas coast during the war, and was described by war-time governor of Texas Francis Lubbock as "undoubtedly the ablest Confederate naval commander in the Gulf waters".

Personal life and family Smith was born in Portsmouth, New Hampshire in 1829. He was a Freemason, and according to some wartime and post-war reports, Caleb Blood Smith, a cabinet member under President Lincoln, was his half-brother.Day, James M.

Pre–Civil War career A mariner from the age of 13, by the time he was 20 Smith was in command of the United States mail steamship Pacific that sailed between San Francisco and Panama.

According to some sources he served in the Texas Navy during the Republic of Texas period.Strangling the Confederacy: Coastal Operations in the American Civil War, Kevin Dougherty, page 27Voices of the Confederate Navy: Articles, Letters, Reports, and Reminiscences, R. Thomas Campbell, page 190Civil War in Texas and the Southwest, Roy Sullivan, page 77

He met John B. Magruder in the late 1840s when engaged in shipping on the West coast. In the 1850s he sailed in the Gulf of Mexico, working for the Southern Mail Steamship Company.

Civil War 1861 – December 1862 In February 1861 he was the captain of the steamer General Rusk and transported General John Salmon Ford and his troops to the mouth of the Rio Grande to receive the surrender of Union Major Fitz John Porter. Unattached to either side, Smith then contracted with Major Porter to transport the Union troops to New York.

In April 1861, back in the Gulf of Mexico, he and his ship General Rusk volunteered for service for the Confederates. On April 18, 1861, Smith and his ship assisted Colonel Earl Van Dorn in the capture of Star of the West (notable for being the target of the first shots of the civil war on January 9, 1861, in Fort Sumter) off Matagorda Bay via trickery: pulling alongside her under the pretense of transferring "friendly" troops which were expected from the transport Fashion. Battle on the Bay: The Civil War Struggle for Galveston, Edward Terrel Cotham, page 21-22 Smith reportedly replying to a hail from Star of the West with "The General Rusk with troops on board. Can you take our line now ?" and explaining that the Fashion would be arriving later with the luggage and the rest of the troops. The boarding troops promptly seized the Star of the West at bayonet point.

Between October 1861 and December 1862 Smith and the General Rusk were under the command of CSN Commander William W. Hunter. On 7 November 1861, Smith and the General Rusk extinguished the fire aboard the stricken Royal Yacht following her encounter with , and towed her back to port.BRILLIANT EXPLOIT IN GALVESTON BAY.; Capture of the Privateer Royal Yacht Attempt to Cut Out the Steamer Rusk Resistance of the Rebels Bravery of the National Forces., NY Times, 19 December 1861

December 1862 – January 1863: Appointment to command, Battle of Galveston Following the retreat from Galveston in the Battle of Galveston Harbor (1862), General Paul Octave Hébert was relieved from command and replaced in November 1862 by General John B. Magruder who arrived in Texas. Previously acquainted with Smith, in December Magruder placed Smith in charge of all the steamers at his disposal.

On Christmas Day 1862, Smith was charged with hastily improvising the , , along with the tenders Lucy Gwinn and the John F. Carr for battle as improvised Cottonclad warships. The Bayou City was outfitted with a single 32-pounder rifled cannon and the Neptune with two 24-pounders howitzers. Cotton bales were used to provide a semblance of protection that was somewhat effective in stopping small arm fire, however when asked by a soldier about artillery protection Smith bluntly replied: "None whatsover... our only chance is to get alongside before they hit us". Boarding devices resembling the Roman Corvus were placed on the hurricane deck of each boat. Facing Smith's forces were vastly superior Union naval forces: , , , , , , and four smaller vessels.The United States Gunboat Harriet Lane, Philip C. Tucker, The Southwestern Historical Quarterly, Vol. 21, No. 4 (Apr., 1918), pp. 360–380

The attack initially planned for 27 December 1862 was delayed to New Year's Eve, the Battle of Galveston. Smith's force was to attack from sea into the Harbor as General Magruder attacked from land crossing over the railroad trestle connecting the island to the mainland. Smith was to wait to be signaled by gunfire that the battle had begun, which was expected to occur at midnight. However, Magruder's forces were delayed by the difficulty of crossing his artillery over the trestle. After no signal came after midnight passed, Smith pulled back from the harbor to Red Fish Bar, a point fourteen miles away. Hearing the attack commencing at 04:00, Smith directed the naval contingent back to the harbor, probably reaching it an hour after the initial shots were fired.

Attacking just before daybreak, the CS Neptune was severely damaged and sunk, but Smith, aboard the CS Bayou City managed to ram into the Harriet Lane, board, and capture her, reportedly personally killing US Navy Commander Jonathan Mayhew Wainwright and recovering a valuable signal book. Though still outnumbered, Smith demanded the surrender of US fleet from commander William B. Renshaw, who had run aground aboard the USS Westfield. While under the flag of truce, Renshaw blew up his vessel and died in the explosion. Smith boarded the USS John F. Carr and captured her as well, while the rest of the US Navy ships escaped to sea.The Seventh Star of the Confederacy: Texas During the Civil War, Kenneth Wayne Howell, page 126 The Lost Cause: A New Southern History of the War of the Confederates, Edward Alfred Pollard, page 365Civil War in Texas and the Southwest, Roy Sillivan, page 80The Civil War Naval Encyclopedia, Volume 1, Spencer Tucker, page 251 Aboard the captured USS John F. Carr, Smith gave chase to the fleeing Union ships, however the small ship was unable to match the speed of the larger warships. Turning around back to the bay, Smith captured three small Union ships (the Cavallo, Elias Pike, and Lecompte) with their cargo.

Following the battle, Smith won praise for his gallant conduct, including a mention in a joint resolution of the Congress of the Confederate States.THE REBEL CONGRESS.; THANKS TO MAGRUDER., New York Times, 24 February 1863 General Magruder attempted to secure a regular Naval commission as commander for him, one of several repeated attempts, which did not result in an actual commission being granted.Texas in the Confederacy: military installations, economy, and people, Bill Winsor, 1978, page 80

January 1863 – August 1864

Following the battle, the Confederate States Navy sent Lieutenant Joseph Nicholson Barney to take charge of naval operations in Galveston, including the captured Harriet Lane. However, after discussions with Magruder who was not willing to relinquish control of the cottonclads, Barney conceded the appointment, and in a letter to Confederate naval secretary Stephen Mallory recommended that the Navy relinquish control. Barney later explained that he made his recommendation since he considered that the presence of two separate marine forces with independent commanders would lead to discord and confusion.Civil War High Commands, John Eicher & David Eicher, page 893

Smith remained in charge of all vessels in Texas, and by order of General Magruder appointed "Commander, Marine Department of Texas".

On September 5, 1863, he was at Orange, Texas, inspecting the Texas and New Orleans Railroad. On September 8 he was at Beaumont, Texas, when a Union force under the command of Major General William B. Franklin with four gunboats, eighteen transports, and 5,000 infantry assaulted up the Sabine River in the Second Battle of Sabine Pass. Smith immediately ordered all Confederate troops in Beaumont, some eighty men, aboard the steamer Roebuck and sent them down the river to reinforce Fort Griffin. Smith and a Captain Good rode to the fort on horseback, reaching the fort some three hours before the steamer, arriving just as the Union gunboats and Sachem came within range of Fort Griffin, which was manned by forty-seven troops. Assisting in the defense of the Fort, Smith took charge of the Clifton and Sachem which were captured during the battle which was one of the most one-sided Confederate victories of the war: no Confederate losses versus 200 killed, wounded or captured Union troops and two lost gunships.Sabine Pass: The Confederacy's Thermopylae, Edward T. Cotham, Jr.The Rise and Fall of the Confederate Government (Complete), Jefferson DavisConfederate Military History: A Library of Confederate States, Volume 11, Clement A. Evans, pages 109–110

From November to December 1863, he was sent by Magruder to direct the naval side of the defense of Indianola, Texas, where Colonel William R. Bradfute was commanding the land forces. As part of the engagement, the Confederates retreated in the Battle of Fort Esperanza. Smith commanded John F. Carr, Cora, and eleven small vessels with sharpshooters and artillery; however disagreements with Bradfute were a hindrance to operations. Smith chose not to take the offensive, fighting defensively.

In early 1864 Brig. Gen. William Steele, who was given command of Galveston, attempted to take control of the naval forces there, however Magruder asserted Smith's authority.

In the summer of 1864, due to better land fortifications and the developing state of the war (most Texas troops were transferred to Louisiana in March), the marine contingent was less needed and Smith was relieved from duty at his request by Captain Henry S. Lubbock (the brother of governor Francis Lubbock and who had been the captain of CS Bayou City (Smith's flagship) in the Battle of Galveston) who commanded the marine department sub-district at Galveston. Smith was ordered by Magruder to report "by letter" to the Confederate States Secretary of the Navy.

August 1864 – June 1865 By 1864, Smith was well known by name to Federal authorities. Following a news report in the Houston Daily Telegraph that Smith was going to be sent to London to acquire a fast steamboat for privateering, that was reprinted by New York papers, Federal authorities attempted to disrupt the alleged scheme.Official Records of the Union and Confederate Navies in the War of the Rebellion, United States Naval War Records Office, 1896, pages 379–380, 398United States Army and Navy Journal, Volume 2: Various Naval Matters, 1 October 1864, page 93Congressional Serial Set: Letter from the Secretary of State to the Secretary of the Navy, regarding the alleged fitting of a cruiser in a British port by Colonel Leon Smith, C.S.
