Beginning in the 1870s, many Civil War generals published memoirs, justifying their decisions or re-fighting old battles, but Thomas, who died in 1870, did not publish his own memoirs.
Fra starten af 1870-erne udgav mange borgerkrigsgeneraler deres erindringer, hvor de begrundede deres beslutninger eller kæmpede gamle kampe om igen, men Thomas, som døde i 1870, offentliggjorde aldrig sine erindringer.
