Vicksburg is the only city in Warren County, Mississippi. It is located 234 miles (377 km) northwest of New Orleans on the Mississippi and Yazoo rivers, and 40 miles (64 km) due west of Jackson, the state capital. In 2010, it became a Micropolitan with a population of 49,644. It is the county seat of Warren County.
During the American Civil War, the city finally had to surrender during the Siege of Vicksburg, after which the Union Army gained control of the entire Mississippi River. The 47-day siege was intended to starve the city into submission. Otherwise its location atop a high bluff overlooking the Mississippi River proved impregnable to assault by federal troops. The surrender of Vicksburg by Confederate General John C. Pemberton on July 4, 1863, together with the defeat of General Robert E. Lee at Gettysburg the day before, has historically marked the turning point in the Civil War. It has been claimed that the residents of Vicksburg did not celebrate the national holiday of 4th of July again until 1945 but this is inaccurate. Large Fourth of July celebrations were being held by 1907 and informal celebrations took place before that.
Because of the city's location on the Mississippi River, in the 19th century it built an extensive trade from the river's prodigious steamboat traffic. Between 1881 and 1894, the Anchor Line, a prominent steamboat company on the Mississippi River from 1859 to 1898, operated a steamboat called the City of Vicksburg. In 1876 a Mississippi River flood cut off the large meander flowing past Vicksburg, leaving limited access to the new channel.
