The author surveys the contributions of Black Americans to the cause of liberty in the United States, arguing that despite systemic enslavement and exclusion they displayed deep commitment and courage. He recounts individual and collective service from the pre-Revolutionary resistance involving Crispus Attucks through Revolutionary War fighters such as Peter Salem and Salem Poor, continued valor in the War of 1812 noted by commanders, and a prominent role in the Civil War after contraband policies and emancipation, highlighting the Massachusetts Fifty-fourth and the assault on Fort Wagner. The essay emphasizes sacrifice, patriotism, and the need for fuller historical recognition of these efforts.
