If you can find an article by Ross Brooks called: "Part Irish and the Rest Flower of Southern Chivalry": Clothing, Arms, and Equipment of the 1st Special Battalion of Louisiana Volunteer Infantry, 1861-1862, there are a couple of pages that summarizes the Tiger execution and what they were wearing. I found the following link, where you can read a PDF file, but I was not able to copy the section about the execution and buriel site investigation - http://www.acws.net/tigers/Part%20Irish%20and%20the%20Rest%20Flower%20of%20the%20Southern%20Chivalry.pdf
