Thirty-Eighth Volunteer Infantry Regiment (Mass.).

The Thirty-Eighth Volunteer Infantry Regiment organized in the summer of 1862 as part of a larger recruiting effort in the state of Massachusetts.

The unit saw its first combat at the Battle of Fort Bisland (April 12-13, 1863). In May of 1863, the unit engaged in battle at Sandy Creek, Missouri, and took part in several assaults on Port Hudson.
