USS Tecumseh was a built for the United States Navy during the American Civil War. Although intended for forthcoming operations against Confederate fortifications guarding Mobile Bay with Rear Admiral David Farragut's West Gulf Blockading Squadron, Tecumseh was temporarily assigned to the James River Flotilla in April 1864. The ship helped to plant obstacles in the river and engaged Confederate artillery batteries in June.

Tecumseh was sunk on 5 August during the Battle of Mobile Bay when she struck a mine. The ship capsized and rests upside down northwest of Fort Morgan. The Smithsonian Institution surveyed her wreck in 1967 with the intent of raising it, but ultimately decided against the project when proffered funding was withdrawn. Several other plans to raise the wreck have been made, but all have fallen through.

Description and construction

The ship was long overall, had a beam of and had a maximum draft of . Tecumseh had a tonnage of 1,034 tons burthen and displaced . Her crew consisted of 100 officers and enlisted men. The engine gave the ship a top speed of . She carried of coal. Tecumsehs main armament consisted of two smoothbore, muzzle-loading, Dahlgren guns mounted in a single gun turret.

The exposed sides of the hull were protected by five layers of wrought iron plates, backed by wood. The armor of the gun turret and the pilot house consisted of ten layers of one-inch plates. The ship's deck was protected by armor thick. A soft iron band was fitted around the base of the turret to prevent shells and fragments from jamming the turret as had happened to the older s during the First Battle of Charleston Harbor in April 1863.

The contract for Tecumseh, named after the Indian chief, She was launched on 12 September 1863 and commissioned on 19 April 1864 with Craven in command.

Service

After commissioning, the ship was ordered to join the North Atlantic Blockading Squadron at Newport News and arrived there on 28 April. Tecumseh was ordered to protect the transports conveying Major General Benjamin Butler's Army of the James up the James River at the beginning of the Bermuda Hundred Campaign on 4 May. To prevent Confederate warships from coming down from the James, the Union forces blocked the channel in mid-June 1864. Tecumseh sank four hulks and a schooner and laid several boom across the river as part of this effort. On 21 June, Commander Craven spotted a line of breastworks that the enemy was building at Howlett's Farm and the ship opened fire at the workers. The Confederates replied with a battery of four guns near the breastworks and her sisters and joined in the bombardment. A half-hour later, Confederate ships near Dutch Gap joined in, but their fire was ineffective because they were firing blindly at the Union monitors. During the engagement, Tecumseh fired forty-six 15-inch shells and was not hit by any Confederate shells. Craven claimed the destruction of one gun emplacement.

Two days after the battle, Tecumseh sailed down the James for Norfolk, Virginia, but ran aground en route when her wire steering ropes broke after having been burned halfway through by the heat of her boilers. She was refloated four hours later and spend a week in Norfolk making repairs and taking on supplies. On 5 July, the ship got underway for Pensacola, Florida to join the West Gulf Blockading Squadron, towed by the side-wheel gunboats and . The ship's engine had overheated en route and required a week's repairs at Port Royal, South Carolina and Augusta had to turn back with engine problems, but Eutaw and Tecumseh arrived in Pensacola on 28 July. Towed by the side-wheel gunboat , the monitor arrived off Mobile Bay on the evening of 4 August.

Farragut briefed Craven on his ship's intended role in the battle. She and her sister were to keep the ironclad ram away from the vulnerable wooden ships while they were passing Fort Morgan and then sink her. The river monitors and were to engage the fort until all of the wooden ships had passed. The four monitors would form the starboard column of ships, closest to Fort Morgan, with Tecumseh in the lead, while the wooden ships formed a separate column to port. The eastern side of the channel closest to Fort Morgan was free of obstacles, but "torpedoes" were known to be present west of a prominent black buoy in the channel.

At 06:47 Tecumseh opened fire on Ft. Morgan's lighthouse to test her guns. The Confederates held their fire until 07:05 when they began to shoot at the ships in both columns. By this time the Confederate ships had positioned themselves across the mouth of the channel, with Tennessee facing the unprotected side, and they started shooting as well. By 07:30 Tecumseh was about away from Tennessee and Craven did not think that he could intercept the Confederate ironclad before entered the channel unless he passed through the field of "torpedoes", as mines were called at the time, because of his ship's poor maneuverability. He ordered the pilot to steer directly for Tennessee. Ten minutes later, Tecumseh struck a "torpedo" 100 yards from the Tennessee but was unable to follow him to safety before the monitor capsized. Including Craven, 94 of the crew went down with the ship. Commander James Jouett of the gunboat dispatched a boat commanded by Acting Ensign Henry C. Nields to rescue any survivors. They successfully rescued ten men, including the pilot, and delivered them to Winnebago. Seven other survivors reached one of Tecumsehs boats and four other men swam ashore and were captured.

In the mid-1960s, the Smithsonian Institution formed the Tecumseh Project Team, which was intended to raise the ship as the centerpiece of a planned National Armed Forces Museum Park in Washington, D. C. The team found the wreck in February 1967, capsized and buried just off Fort Morgan, but the primary donor was forced to rescind the funding, so the project was suspended. "In a 1993 survey, archaeologists from East Carolina University reported the hull to be covered by a calcareous crust with only nominal surface deterioration present."

In 1974, Jack Friend – a Mobile naval historian – was commissioned to examine the feasibility of raising Tecumseh and concluded that it would cost an estimated $10 million. More modern estimates have determined a salvage and conservation cost of $80 million. Divers from the Smithsonian Institution recovered an anchor, dishes from the ship's dining hall and a variety of other artifacts during their 1967 expedition. Tecumsehs engine room gong was also removed and is currently on display at the Hampton Roads Naval Museum. The wreck site is marked and under United States Coast Guard surveillance pending continued preservation efforts. She is considered a war grave and may not be disturbed without permission of the United States Secretary of the Navy.
