should take their word for it. It is perhaps not surprising that in 1864 the black men of the Fourteenth Rhode Island Heavy Artillery reminded one another that "upon your prowess, discipline, and character; depend the destinies of four millions of people." It may be more surprising to find a white Union soldier writing in 1862 that "the fact that slavery is the sole undeniable cause of this infamous rebellion, that it is a war of, by, and for Slavery, is as plain as the noon-day sun." That same year a soldier on the other side, in Morgan's Confederate Brigade, wrote that "any man who pretends to believe that this is not a war for the emancipation of the blacks . . . is either a fool or a liar." Manning can and does multiply these examples, and she finds that they vastly outweigh the evidence for any other dominant motive among the combatants. She freely concedes that there are paradoxes in Northern attitudes. Many Northerners initially combined a detestation of slavery with unpleasant views of their black countrymen. She suggests that a focus on the latter attitude has obscured awareness of the intensity and breadth of the former one, and she points out that closer acquaintance with slavery, a result of waging war on Confederate soil, only intensified soldiers' loathing of it. Encounters with the sexual and child exploitation that slavery made possible were especially likely to produce this reaction. She quotes many eloquent examples. Sgt. Cyrus Boyd, of
