20th Maine Regimental Flag

• This regiment's flag bore the eagle of the American republic centered on a blue background. The eagle holds in its beak a ribbon which says: "E Pluribus Unum," which means, "One from many" in Latin a standard principle of the Union for which the 20th Maine fought. This flag received lasting fame due to this regiment's excellent performance at the battle of Gettysburg, saving the battle for the Union army and perhaps even the war.
  
  

The Union Irish Brigade

• The flag of the Irish Brigade had a green background. The image depicted a heavenly light and a harp to illustrate the holy cause they fought for. A statement in old Irish language spanned the lower half which meant: "Who never retreated from the clash of spears." The regiment remained true to this motto, never once retreating without orders and nearly always leading the way of a major assault.
  
  

The Bonnie Blue Flag

• This flag was blue with a single star in the middle. It was originally used by several independent American republics in Florida, Mississippi, and Texas. When the Confederacy was formed in 1861, the flag was often used to symbolize the same spirit of independence with which these old republics were formed. Though rarely used as the primary flag of a regiment, several traveled with each army and they were included in army marches and reviews. The design received lasting immortality when "The Bonnie Blue Flag" quickly became the most popular marching song of the Confederacy.
  
  

Army of Northern Virginia Battle Flag

• The battle flag of the Army of Northern Virginia was a square, red flag marked by a blue "X" with stars. It was used as the regimental flag of most of the army's units, who merely stitched their regiment's name into the fabric. Because the future of the Confederacy was closely tied to the success or failure of this army led by Robert E. Lee, the battle flag came to be equated with the Confederacy itself. As of 2011, there are few people who make the distinction between a confederate flag and the battle flag of the Army of Northern Virginia.
