I thought this news clip would prove interesting to note in this 150th anniversary year of the Emancipation Proclamation and the formal acceptance of armed Black soldiers in the United States Army. However, there were already regiments composed of men of African descent serving such as the 1st South Carolina Infantry (African Descent).
