Seeing the South's leading warriors dressed in Union blue
As a fan of military history I should not be surprised but it was still astonishing for me to actually see the Confederacy's early generals still wearing the Union blue uniform at the outset of the Civil War. Of course it made historical sense. There was no Confederate Army standard uniform just yet although it was in the finishing stages. The South's premier officers had just resigned from the Federal Army and still wore their blue uniforms.
If you're from the South it may seem like blasphemy to see Robert E. Lee in his Federal's colonel blue uniform, 'Stonewall' Jackson dressed sharply in his Federal major's uniform, and Jeb Stuart dressed dashingly in his Federal lieutenant colonel's cavalry blue uniform. Yet it was all accurate. These men all wore the blue uniform, proudly, and much longer than they did in the Confederate grey uniform.
At the movie's beginning there are scenes of southern men still wearing the blue uniform as the South organizes for war.
In another scene where Stonewall Jackson, still wearing his Federal blue uniform is speaking to a father and son, his shoulder epaulettes indicate he has been promoted from major (gold oak leaves) to full colonel (silver eagles).
