History & geography

History

The city was named in honor of U.S. Army Sergeant Charles Floyd, a native of Kentucky who was one of the first men to enlist in the Lewis and Clark Expedition in the early 1800s. Just three months into the two-year journey, Floyd became violently ill and died the next day, August 20, 1804, of what is believed to have been a ruptured appendix. He was buried on a hill overlooking an unnamed river on the Iowa side of the Missouri River. In his honor, the expedition's leaders, Meriwether Lewis and William Clark, named the river Floyd River and the hill Floyd's Bluff, now part of Sioux City. Floyd was the expedition's only casualty. The village of Sergeant Bluff was started in 1852, south of what became Sioux City, and under the name of Sergeant's Bluff City, it become the first town in Woodbury County. The city was incorporated May 2, 1904 in the centennial year of Floyd's death.
