In what capacity did Frederick Douglass influence the Union cause?

Frederick Douglass significantly influenced the Union cause during the Civil War mainly through his efforts to encourage enlistment among African Americans. He understood that the fight for freedom and equality for enslaved people was inherently tied to the Union's victory. Douglass argued passionately that African American soldiers would not only help secure the Union's triumph but also earn their rightful place in American society. His speeches and writings highlighted the courage and capability of African Americans to serve in the armed forces, visibly changing the perception of their role in the war effort. This advocacy was crucial in persuading many African Americans to join the fight, which helped to bolster the Union army both in numbers and in moral imperative.

Other approaches, such as promoting peace efforts or leading protests against the draft, did not align with Douglass's urgent call for action during the Civil War, as he believed that immediate engagement in the fight for freedom was crucial. Although Douglass did have considerable knowledge of military strategy, it was his emphasis on the involvement of African Americans that marked a key element of his impact during this period.
