Powerful racial prejudices? That was not true of Thomas Wentworth Higginson, or Norwood P. Hallowell, or George T. Garrison, or many other abolitionists and sons of abolitionists who became officers in black regiments. Indeed, the contrary was true.

That is why they jumped at the chance of help launch an experiment with black soldiers which they hoped would help African Americans.
