Although it was never officially adopted by the Confederate government, the popularity of the Southern Cross among both soldiers and the civilian population was a primary reason why it was made the main color feature when a new national flag was adopted in 1863. This new standard – known as the "Stainless Banner" – consisted of a lengthened white field area with a Battle Flag canton. This flag too had its problems when used in military operations as, on a windless day, it could easily be mistaken for a flag of truce or surrender. Thus, in 1865, a modified version of the Stainless Banner was adopted. This final national flag of the Confederacy kept the Battle Flag canton, but shortened the white field and added a vertical red bar to the fly end.
