Read the excerpt from "We Are All Bound Up Together” by Frances Ellen Watkins Harper.

When Judge Taney said that the men of my race had no rights which the white man was bound to respect, he had not seen the bones of the black man bleaching outside of Richmond. He had not seen the thinned ranks and the thickened graves of the Louisiana Second, a regiment which went into battle nine hundred strong, and came out with three hundred. He had not stood at Olustee and seen defeat and disaster crushing down the pride of our banner, until words was brought to Col. Hallowell, "The day is lost; go in and save it;” and black men stood in the gap, beat back the enemy, and saved your army.
