Abraham Lincoln's wartime decisions, particularly regarding emancipation, were driven by a combination of military strategy and political maneuvering aimed at preserving the Union and undermining the Confederacy's resources.
The passage that best explains Lincoln's motivation while making wartime decisions can be encapsulated by his notion of military necessity and the delicate balance he had to maintain politically. Abraham Lincoln believed that clinging to the goal of preserving the Union was of paramount importance.
At first, he was cautious about embracing emancipation as a policy because of political risks, including the potential secession of the Border States as well as Democratic opposition. Nonetheless, by mid-1862, as military setbacks mounted, Lincoln started shifting towards emancipation not only as a moral imperative but as a vital war strategy.
He perceived that the abolition of slavery would weaken the South's capacity to maintain their war effort and boost the North's manpower through the recruitment of African American soldiers. Additionally, Lincoln's Emancipation Proclamation served as a diplomatic tool to deter British support for the Confederacy.
Ultimately, his approach evolved, realizing that he could neither satisfy all parties nor could he ignore the pressing military and moral demands. By issuing the Emancipation Proclamation, he not only transformed the nature of the Civil War but also laid the groundwork for the eventual abolition of slavery and the reorganization of Southern states into the Union post-war.
