The Battle of Island Mound State Historic Site is located in a rural area of Bates County, Missouri, in the western part of the state.
 The site was established in 2012 to preserve the area of the American Civil War battle that took place in October 28-29, 1862 between Union forces and Confederate guerrillas.
 The battle was significant as the first time African-American troops on the Union side engaged enemy white troops in the Civil War.
 A "New York Times" correspondent reported on the battle; the headline noted the "desperate bravery" of the African Americans in achieving Union victory.
Edisto Island during the American Civil War was the location of a number of minor engagements and for a time of a large colony of African-American escaped former slaves during the American Civil War (1861–1865).
 Edisto Island was largely abandoned by planters in November 1861 and in December 1861, escaped slaves began setting up their own refugee camps there.
 In January 1862, armed African Americans from the island and Confederate forces clashed and a Confederate raid in reprisal killed a small number of unarmed African Americans.
 In February, Union forces were stationed on the island to develop it as a staging area for future campaigns against Charleston, twenty-five miles away, as well as to protect the colony, which would eventually number thousands of African Americans.
 As Union forces took control of the island, a number of skirmishes occurred, but Confederates withdrew.
 In June, most of the Union troops left the island in a campaign, which culminated in the Battle of Secessionville.
 In July, the remaining troops withdrew, and the colony was removed to St. Helena Island.
 For the rest of the war, a small number of escaped slaves and plantation owners remained and farmed the island, but it was largely abandoned.
 Near the end of the war, the island was again used as a location of colonies of freed slaves.
The Battle of Natural Bridge was a battle during the American Civil War, fought in what is now Woodville, Florida, near Tallahassee, on March 6, 1865.
 A small band of Confederate troops and volunteers, mostly composed of teenagers from the nearby Florida Military and Collegiate Institute that would later become Florida State University, and the elderly, protected by breastworks, prevented a detachment of United States Colored Troops from crossing the Natural Bridge on the St. Marks River.
 The Natural Bridge is a one-quarter mile long stretch along which the St. Marks River runs underground, after dropping into a sinkhole.
 This action prevented the Union Army from capturing the Florida capital and made Tallahassee the only Confederate capital east of the Mississippi River not to be captured by Union forces during the war.
 The battle has been described as the last Confederate victory in the American Civil War, and it was the second largest American Civil War battle in Florida.
William T. Anderson (1840 – October 26, 1864)—known as "Bloody Bill" Anderson—was one of the deadliest and most brutal pro-Confederate guerrilla leaders in the American Civil War.
