The chief purpose of battle flags was to serve as rallying points amid the chaos of combat. For this purpose, unit flags were often more important than the over-arching flag of the Confederacy. Perhaps for this reason, the flag of Lee's army, with its distinctive X-like St. Andrew's cross, is almost universally mistaken for the Confederate flag. The actual design of the first flag of the Confederacy was the "Stars and Bars," represented in five of the seven flags in this section. The flag of the Combined 6th and 7th Regiments is a classic example of the "Stainless Banner" design, while the flag of the King's 22nd/20th Regiment represents an unusual variation of that design.
