“Mosby, Rhett, Davis, Stephens, and other Confederates had no difficulty conceding what their descendants go to enormous lengths to deny, that the raison d'être of the Confederacy was the defense of slavery. It follows that, as the paramount symbol of the Confederate nation and as the flag of the armies that kept the nation alive, the St. Andrew's cross is inherently associated with slavery. This conclusion is valid whether or not secession was constitutional. It is valid whether or not most southern soldiers consciously fought to preserve slavery. It is valid even though racism and segregation prevailed among nineteenth-century white northerners.”

Context: It would be wrong, however, to assume that Confederate soldiers were constantly preoccupied with this matter. In fact, only 20 percent of the sample of 429 Southern soldiers explicitly voiced proslavery convictions in their letters or diaries. As one might expect, a much higher percentage of soldiers from slaveholding families than from nonslaveholding families expressed such a purpose: 33 percent, compared with 12 percent. Ironically, the proportion of Union soldiers who wrote about the slavery question was greater, as the next chapter will show. There is a ready explanation for this apparent paradox. Emancipation was a salient issue for Union soldiers because it was controversial. Slavery was less salient for most Confederate soldiers because it was not controversial. They took slavery for granted as one of the Southern 'rights' and institutions for which they fought, and did not feel compelled to discuss it. Although only 20 percent of the soldiers avowed explicit proslavery purposes in their letters and diaries, none at all dissented from that view. But even those who owned slaves and fought consciously to defend the institution preferred to discourse upon liberty, rights, and the horrors of subjugation.
