According to Brook, "in every age, a heroic sage struggles to rescue Benjamin from obscurity—and invariably fails." Benjamin left no memoir and destroyed his personal papers, by which "the task of future researchers and historians was made exceedingly difficult and laborious". After his death, Benjamin was rarely written about, in contrast to Davis and other Confederate leaders. Part of this was due to Benjamin depriving his potential biographers of source material, but even Davis, in his two-volume war memoir, mentions him only twice. Evans suggests that as Davis wrote the books in part to defend and memorialize his place in history, it would not have been characteristic of him to give much credit to Benjamin. Davis, in the midst of postwar business struggles, may have resented Benjamin's success as a barrister, or may have feared that allegations of involvement in Lincoln's assassination would again be made against the two men. Brook concurs that Benjamin's postwar success, that began as Davis lay in prison and other Confederates struggled for survival, may have soured Southerners towards the former secretary, but that anti-Semitism was also likely a factor. "For the guardians of Confederate memory after Reconstruction, Benjamin became a kind of pet Jew, generally ignored, but then trotted out at opportune moments to defend the segregated South against charges of bigotry."
