Im throwing this out hoping to find a few leads on Colonel Stuart W. Fisk. Fisk was made colonel of the 25th Louisiana when it was organized in March in New Orleans. He was killed at Murfreesborough on December 31, 1862 while attacking the Round Forrest at the front of the 16th & 25th Louisiana.

I was able to find out that Fisk was actually the captain of Company B, Crescent Rifles, of Dreux's 1st Louisiana Battalion. He went with the unit to Virginia and when Dreux was wounded in July Fisk took command of the battlion for awhile.

I have the info from Booth which is extremely small (Rightor was Major of the 1st Louisiana Battalion and it wasnt the Special Battalion of Wheats):

Fisk, S. W., Capt. Co. B, 1st Special Battn. (Rightor's) La. Inf. En. April 15, 1861, New Orleans, La. Roll to May 31, 1861, shows him sick. Present or absent not stated on Roll for May 31 to June 30, 1861. Roll for July and Aug., 1861, Absent on sick furlough in Richmond.

Fisk, S. W., Col., F. and S., 25th La. Inf. Appears on Roster dated March, 1865. En. March 20, 1862. Apptd. Col., War Dept., March 20, 1862. Killed in action Dec. 31, 1862; successor, J. C. Lewis.

This is all I can find of Fisk. Would be interested in finding some more info on this gentleman. He personally paid over $19,000 out of his own pocket to buy the 25th Louisiana tents, blankets, shoes, material and the labor to make 800 uniforms and just about everything but guns. There remained a continued campaign on his widow's behalf into 1865 to get the Confederate government to reimburse her for his investment.
