Final answer:
Lincoln used military resources like enlisting freed slaves in the Union army to enforce the Emancipation Proclamation, faced backlash from the South, and established a moral connection through his emphasis on justice and a new union without slavery.
Step-by-step explanation:
President Lincoln mentioned using the military resources of the Union to implement the Emancipation Proclamation, such as enlisting freed slaves into the Union army. The reaction from the southern states to Lincoln's actions was predominantly negative, with leaders universally denouncing the proclamation and reinforcing their commitment to maintain slavery. Furthermore, Lincoln's language in the closing paragraph of his address establishes a moral connection to the proclamation by framing the issue in terms of justice and a vision for a new union without slavery, thereby aligning the legal action with ethical imperatives.
Resources mentioned by Lincoln include armed and drilled black soldiers, which he believed would be a significant force against the rebellion. The expected reaction of southern states was one of resistance and denouncement. Through his eloquent language focused on unity and the moral wrongness of slavery, Lincoln established a strong moral connection to the proclamation's underlying principles.
