My family fought in the West the whole war, Veteran Volunteers, Union, lost one or two.
I am a Longstreet fan but Lee did what he had to do to expand the war and bring the Limeys in, which I believe was the plan. He screwed up at Gettysburg, wrong attack at the wrong place. He was an honorable man.
My great grandmother’s uncle and father joined the Union army on the same day but her uncle later switched sides and fought for the south.
I read some letters my great great grandfather wrote to his parents both during the war and after. He called it “This damnable war that no one desires anymore”. He spoke of confederate POWs seeking news of family members fighting on the union side and union soldiers asking confederate POWs for news about family members fighting on the confederate side.
