My initial feeling when I saw this was, is this some college student who's looking for forum members to do his or her work for a research paper? But as a member with hundreds of posts, I have to give you the benefit of the doubt.
So: if you define "losers" as Confederates, then all you need to do is perform a search of former Confederates, and see what books they wrote. There may well be hundreds of them. Among the most prominent:
•
The Rise and Fall of the Confederate Government (1881) by former CSA President Jefferson Finis Davis.
• These are books by Virginia journalist and writer Edward Alfred Pollard,
per Wiki:
- The Southern History of the War; 3 vols.:
- First Year of the War, with B. M. DeWitt, 1862
- Second Year of the War, 1864
