Answer:
Lincoln's announcement of the Emancipation Proclamation
Step-by-step explanation:
Douglass delivered this speech, “Men of Color, To Arms!”, in Rochester, New York on March 2, 1863 to help mobilize African Americans toward enlistment. He urged his fellow free men of color that they had to act to help insure the complete abolition of slaves
For the first two years of the Civil War black and white abolitionists urged both the liberation of the slaves and the recruitment of African American men in defense of the Union. Barely three months after Lincoln’s Emancipation Proclamation went into effect, Frederick Douglass gave a speech in Rochester, New York on March 2, 1863, titled “Men of Color, To Arms!” which urged African American men to join what was increasingly a war to make real what the Proclamation only promised—complete freedom.
