Solomon J. L. Andrews applied for a pension and
stated that he served in the 6th Cavalry, Company I.

He stated the following in his application:
1. enlisted at Hineston in 1863
2. taken prisoner in Calcasieu Parish and taken to New Orleans
3. released at Alexandria and paroled at Washington
4. at Alexandria at the time of the surrender

In Booth's Records of Louisiana Confederate Soldiers are the following 2 records:

Andrews, S. J. L.
Pvt. 4th La. Cavalry. Federal Rolls of Prisoners of War Captured Near Alexandria, La., March 20th, 1864. Recd. at New Orleans. La., April 25th, 1864. Transfd. from New Orleans, La., and Exchanged at Red River Landing, July 22nd, 1864.

Andrews, Solomon
Pvt. Co. I. 6th La. Cavalry. Roll dated Feb. 20th, 1864, "En. Feb. 19th, 186_, for the war by W. E. Irby."

My question:
Did Solomon J. L. Andrews who applied for the pension serve in both the 4th and 6th Cavalry, or only the 6th Cavalry? Would serving in both the 4th and the 6th Cavalry been possible? Or perhaps the 4th Cavalry is a clerical error: someone incorrectly recorded the 4th instead of the 6th? Or do the above 2 records belong to 2 different men? Andrews never mentions the 4th in his application.

I would be most appreciative of any help with this question.

Thank you.
