Those are the best and most enjyable of overviews, with some detail, of the war, in my opinion.
If you want battle details, look elsewhere.
I'll second your opinion of Foote's trilogy. It is truly incredible. It started out slow for me in the 1st volume, but by the time I finished the 3rd, I hated to see it end, and talk about a huge sense of loss when it was finished! I'll probably reread them again in a couple of months. Foote's narrative prose is a thing of beauty. A friend of mine who was an English major, but loved history, said that he had to be careful reading Foote, because it would subconsciously influence his own writing style when doing college papers.
