Henry Clay Merriam was a United States Army general. He received the United States military's highest decoration, the Medal of Honor, for his actions as a Union officer in command of African American troops during the American Civil War. He later served in various Indian Wars throughout the western United States and commanded the 7th Infantry Regiment. After being promoted to brigadier general, he took on a training and supply role during the Philippine–American War.

The 1st Louisiana Native Guard was one of the first all-black regiments in the Union Army. Based in New Orleans, Louisiana, it played a prominent role in the Siege of Port Hudson. Its members included a minority of free men of color from New Orleans; most were African-American former slaves who had escaped to join the Union cause and gain freedom. A Confederate regiment by the same name served in the Louisiana militia made up entirely of free men of color.
