Miles' Legion was a unit of the Confederate Army during the American Civil War. It was commanded by Col. William R. Miles. The unit was officially named the 32nd Louisiana Infantry Regiment but it was never referred to by that name. The legion fought at the Battle of Plains Store and the Siege of Port Hudson. Captured at Port Hudson, the men were paroled, and the legion was declared exchanged in fall 1863. Many of the exchanged men never returned to duty. Those who did return joined Gober's Mounted Infantry Regiment or the 15th Louisiana Sharpshooter Battalion.
