This is just what it says in Wiley Sword's "The Confederacy's Last Hurrah". 1992.
Page: 246, "In the forefront of the attack was Brigadier General Jacob. H. Sharp's command, known as the "High Pressure Brigade" due to their past tenacious fighting. The 41st Mississippi infantry was among the regiments struggling to crawl, prod, and force their way through the tangled locut branches "that ordinarily a dog could not have gotten through." Up to the Federal breastworks dashed these Mississipians. A color-bearer, shouting for those behind him to follow him, clambered over the parapet waiving his flag. Immediately he was engaged in a hand-to-hand struggle for the colors. Behind him some soldiers of the 41st tumbled over the works, and a vicious bayonet fight erupted in the dark. Moments later the enemy seemed to vanish in the direction of the retrenched line, leaving several stands of colors behind. *6
* "Apparently the flag of the 72nd Illinois was lost at this point, the color sergeant having "sneaked away" before eight corporals of the color guard were either shot or captured.
This is all from Wiley Sword's book. It also cover Spring Hill and nashville.
I checked the back of the book in reference notes. *6 is from Ibid Banks 44-47. I'm very curious to read more on that.
I shall check in detail on the 111th Ohio, 107th Illinois, 129 Indiana, 23rd Michigan and the 118th Ohio. At least we have it down to 5 Union regiments that had to have lost a flag to Sharp's brigade. You agree?
I'll see what I can find out, will keep you and everyone else informed.
Have a good weekend, everyone.
