A second good source is Allan Nevins 7 volume history of the Civil War. Foote’s work (which I find excellent) does have a slight Southern bias. Understandable, he was from the South. Nevins’ work is as good as Foote, but with a slight Northern bias.He was from Illinois.
I have read Nevins but just recently read Foote. You are right about his feelings about the War but it doesn’t interfere with his descriptions or truths.
After all the boy was born in Greenville, Mississippijust down the road from my boyhood home. My ancestors were from Mississippi and Alabama, in fact my maternal grandmother was named “Alabama”. Of course we called her “Bama.”
