25 mounted members of the New Orleans Metropolitan Police to Colfax, Louisiana in October to apprehend the perpetrators of the Colfax Massacre. Due to widespread resistance by local whites, only a few men were arrested and transported to New Orleans by Ozark to stand trial in December. Prosecution witnesses were transported and housed in the ship during the trials in February–March 1874 to protect them from threats made by white supremacists. Nothing further is known about the Ozarks activities or fate. Notes References Further reading Monitors of the United States Navy Ships of the Union Navy Ships built in Mound City, Illinois 1863 ships
