OK, hope this doesn't sound ASB, but is there any way the ACW could've eventuated to the extent of whites and blacks being integrated into the same combat regts (not just OTL brigading of black & white combat units together) ? Perhaps an even greater loss rate of able-bodied white northern males which compels the Army to put in blacks and whites in the same regts tog- just as occurred during the Korean War with the replacements shortage ? What effect on race relations etc ? Of course, many northern whites at the outset of the war saw blacks as inferiors and inherently unequal as much as white Southerners did, but as the war progressed, the majority started to change their minds bout the fighting capability and humanity of the black man due to such heroic events as Fort Wagner- how much more so if the Union army had blacks and whites fight and die side-by-side in the same units ?
