The siege of Port Hudson was the final engagement in the Union campaign to recapture the Mississippi River in the American Civil War. While Union General Ulysses Grant was besieging Vicksburg upriver, General Nathaniel Banks was ordered to capture the lower Mississippi Confederate stronghold of Port Hudson, Louisiana, to go to Grant's aid. When his assault failed, Banks settled into a 48-day siege, the longest in US military history up to that point. A second attack also failed, and it was only after the fall of Vicksburg that the Confederate commander, General Franklin Gardner, surrendered the port. The Union gained control of the river and navigation from the Gulf of Mexico through the Deep South and to the river's upper reaches.

The history of New Orleans, Louisiana traces the city's development from its founding by the French in 1718 through its period of Spanish control, then briefly back to French rule before being acquired by the United States in the Louisiana Purchase in 1803. During the War of 1812, the last major battle was the Battle of New Orleans in 1815. Throughout the 19th century, New Orleans was the largest port in the Southern United States, exporting most of the nation's cotton output and other farm products to Western Europe and New England. As the largest city in the South at the start of the Civil War (1861–1865), it was an early target for capture by Union forces. With its rich and unique cultural and architectural heritage, New Orleans remains a major destination for live music, tourism, conventions, and sporting events and annual Mardi Gras celebrations. After the significant destruction and loss of life resulting from Hurricane Katrina in 2005, the city would bounce back and rebuild in the ensuing years.
The Mississippi River Delta is the confluence of the Mississippi River with the Gulf of Mexico in Louisiana, southeastern United States. The river delta is a three-million-acre area of land that stretches from Vermilion Bay on the west, to the Chandeleur Islands in the east, on Louisiana's southeastern coast. It is part of the Gulf of Mexico and the Louisiana coastal plain, one of the largest areas of coastal wetlands in the United States. The Mississippi River Delta is the 7th largest river delta on Earth (USGS) and is an important coastal region for the United States, containing more than 2.7 million acres of coastal wetlands and 37% of the estuarine marsh in the conterminous U.S. The coastal area is the nation's largest drainage basin and drains about 41% of the contiguous United States into the Gulf of Mexico at an average rate of 470,000 cubic feet per second.

Ship Island is a barrier island off the Gulf Coast of Mississippi, one of the Mississippi–Alabama barrier islands. Hurricane Camille split the island into two separate islands in 1969. In early 2019, the US Army Corps of Engineers completed the first stage of a project rejoining the two islands and recreating one Ship Island. Ship Island is the site of Fort Massachusetts, as a Third System fortification. Part of the island is included in the Gulf Islands National Seashore.
Drainage in New Orleans, Louisiana, has been a major concern since the founding of the city in the early 18th century, remaining an important factor in the history of New Orleans today. The central portion of metropolitan New Orleans is fairly unusual in that it is almost completely surrounded by water: Lake Pontchartrain to the north, Lake Borgne to the east, wetlands to the east and west, and the Mississippi River to the south. Half of the land area between these bodies of water is at or below sea level, and no longer has a natural outlet for flowing surface water. As such, virtually all rainfall occurring within this area must be removed through either evapotranspiration or pumping. Thus, flood threats to metropolitan New Orleans include the Mississippi River, Lake Pontchartrain, canals throughout the city, and natural rainfall. Artificial levees have been built to keep out rising river and lake waters but have had the negative effect of keeping rainfall in, and have failed on numerous occasions.
Algiers Point is a location on the Lower Mississippi River in New Orleans, Louisiana.

La Balize, Louisiana was a French fort and settlement near the mouth of the Mississippi River, in what later became Plaquemines Parish. The village's name meant "seamark." La Balize was historically and economically important for overseeing the river. It was rebuilt several times because of hurricane damage. The active delta lobe of the river's mouth is called the Balize Delta, after the settlement, or the Birdfoot Delta, because of its shape.
