A column by the Washington Post's Editorial Board discussed history professor Allen Guelzo and his research on slavery during the Civil War. The column focused on Martin Luther King Jr.'s methods of non-violence and his faith in the American people.
From the Washington Post:
It was not a new phenomenon. Many of the men who fought to preserve the Union — probably most of them — had little interest in freeing the slaves. Yet as they moved south, saw the faces and witnessed the conditions under which many enslaved people lived, they gained a new sympathy and understanding of how awful it was. Historian Allen Guelzo writes that Union naval officers “who had some chance ashore to see the remains of the slave system for themselves experienced great awakenings.” Adm. Samuel F. Du Pont, who acknowledged that he had once been “a sturdy conservative” on the question of slavery, “was horrified by the conditions he found on the coastal plantations,” writes Mr. Guelzo. Having seen the institution of slavery in person, Du Pont wrote to a friend, “may God forgive me for the words I have uttered in its defense as intertwined in our Constitution.”
