Just scrolled through this thread and viewed the various Don Troiani artwork.
Troiani's painted works clearly provide dramatic, vivid and colorful depictions of famous leaders, uniforms worn and events of the CW.
But most, if not all, of this artwork are romanticized (or ideal) palatable versions, without necessarily reflecting the grim realities of the conflict. For instance, the scenes painted generally do not show show the full extent of the blood and gore on the battlefield, nor the tattered and inadequate uniforms often worn by supply-deprived combatants.
Nevertheless, thought Troiani's recreations fill a gap for presenting useful information on the CW.
In saying this, my personal favorite of Troiani's paintings is the third display in the OP, showing Cleburne leading his division at Franklin.
