This was a look at the American Civil War from the viewpoint of an African American soldier serving in the Northern Army, in the famous 54th Massachusetts Volunteer Infantry. It offers a viewpoint of the War, not normally written about.
One of the most fascinating parts about this book, is the armed African American Confederate soldiers, who were captured on Morris Island, SC.
What makes this more interesting is that Pulitzer Prize winner, James M. McPherson, who attacked author Joy Masoff, for including black Confederates in her book, "Our Virginia: Past and Present," wrote the Foreword for this book and therefore knew that blacks fought for the South before he criticized her in a Washington Post article.
