The Union Iron Works (first known as Carondelet Marine Railway Company and later as Union Marine Works) was a shipbuilding and engineering firm in Carondelet, St. Louis, Missouri, United States.
It was founded in the 1850s by Primus Emerson as the Carondelet Marine Railway Company. It sat where Marceau Street, off South Broadway, met the Mississippi River. The yard had tracks and cranes that could haul ships in or out of the river using a railway car that descended into the water, mated with a ship's hull, and was hauled up the bank and into one of a handful of sheds. The yard employed 800 artisans, laborers and shipwrights. [1]
In 1861, riverboat salvager and engineer James Eads leased the yard and used it to build ironclads for the Union Navy during the American Civil War. In 1869 and 1870, facilities of the Union Iron Works were used by William Nelson and Co. to fabricate the caissons used to build Eads Bridge.

After completion in mid-1863, the ship spent time patrolling the Mississippi River against Confederate raids and ambushes as part of Rear Admiral David Porter's Mississippi Squadron. She participated in the Red River Campaign in March–May 1864. Neosho resumed her patrols on the Mississippi after the end of the campaign.

USS Osage was a single-turreted Neosho-class monitor built for the Union Navy during the American Civil War. After completion in mid-1863, the ship patrolled the Mississippi River against Confederate raids and ambushes as part of Rear Admiral David Porter's Mississippi Squadron. Osage participated in the Red River Campaign in March–May 1864, during which she supported the capture of Fort DeRussy in March and participated in the Battle of Blair's Landing in April. The ship was grounded on a sandbar for six months after the end of the campaign and badly damaged. Osage, after being refloated and repaired, was transferred to the West Gulf Blockading Squadron in early 1865 for the campaign against Mobile, Alabama. During the Battle of Spanish Fort in March 1865 she struck a mine and rapidly sank. The ship was later salvaged and sold in 1867.
USS Ozark was a single-turreted river monitor built for the United States Navy during the American Civil War. The ship served in the Mississippi River Squadron during the war, and participated in the Red River Campaign shortly after she was commissioned in early 1864. Ozark patrolled the Mississippi River and its tributaries after the end of the campaign for the rest of the war. She was decommissioned after the war and sold in late 1865.
USS Kickapoo was a double-turreted Milwaukee-class river monitor, the lead ship of her class, built for the Union Navy during the American Civil War.

She was placed in reserve after the end of the war and sold in 1874.
The first USS Milwaukee, a double-turreted Milwaukee-class river monitor, the lead ship of her class, built for the Union Navy during the American Civil War. The ship supported Union forces during the Mobile Campaign as they attacked Confederate fortifications defending the city of Mobile, Alabama in early 1865. She struck a mine in March and sank without loss. Her wreck was raised in 1868 and broken up for scrap that was used in the construction of a bridge in St. Louis, Missouri.
The Battle of Grand Gulf was fought on April 29, 1863, during the American Civil War. As part of Major General Ulysses S. Grant's Vicksburg campaign, seven Union Navy ironclad warships commanded by Admiral David Dixon Porter bombarded Confederate fortifications at Grand Gulf, Mississippi. One of the Confederate fortifications, named Fort Wade, was silenced, but the other, named Fort Cobun, continued firing. Due to the strong Confederate resistance, Grant and Porter decided it was not feasible to make an amphibious landing at Grand Gulf, but later landed at Bruinsburg, Mississippi, instead. After the Confederates were defeated at the Battle of Port Gibson on May 1, Grand Gulf was rendered indefensible and the fortifications were abandoned. The defenders of Grand Gulf then fought at the Battle of Champion Hill on May 16 and the Battle of Big Black River Bridge on May 17, before the start of the Siege of Vicksburg, which ended with a Confederate surrender on July 4. Today, the battlefield is preserved in Grand Gulf Military State Park, which was listed on the National Register of Historic Places in 1972.

The Delaware River Iron Ship Building and Engine Works, was a major late-19th-century American shipyard located on the Delaware River in Chester, Pennsylvania. It was founded by the industrialist John Roach and is often referred to by its parent company name of John Roach & Sons, or just known as the Roach shipyard. For the first fifteen years of its existence, the shipyard was by far the largest and most productive in the United States, building more tonnage of ships than its next two major competitors combined, in addition to being the U.S. Navy's largest contractor. The yard specialized in the production of large passenger freighters, but built every kind of vessel from warships to cargo ships, oil tankers, ferries, barges, tugs and yachts.
The Neosho-class monitors were a pair of ironclad river monitors laid down in the summer of 1862. After completion in mid-1863, both ships spent time patrolling the Mississippi River against Confederate raids and ambushes as part of Rear Admiral David Porter's Mississippi Squadron. Both ships participated in the Red River Campaign in March–May 1864, although Osage supported the capture of Fort DeRussy in March and participated in the Battle of Blair's Landing in April. Osage was grounded on a sandbar for six months after the end of the campaign while Neosho resumed her patrols on the Mississippi. The latter ship supported the Union Army's operations on the Cumberland River and provided fire support during the Battle of Nashville in December.
The Milwaukee-class monitors were a class of four riverine ironclad monitors built during the American Civil War. Several supported Union forces along the Mississippi River in mid-1864 before participating in the Battle of Mobile Bay in August. Chickasaw and Winnebago bombarded Confederate coastal fortifications during the battle and during subsequent operations as well as engaging the ironclad Tennessee II. The other two ships arrived at Mobile Bay after the battle and all four supported the land attacks on Mobile in March–April 1865. Milwaukee struck a torpedo during this time and sank. The surviving three ships were sold in 1874; Chickasaw was converted into a ferry and survived until 1944 when she was scuttled. Her wreck was discovered in 2004.
