EXPLANATIONS BELOW
Concept note-1: -Emancipation as Political-Military Strategy. Lincoln’s strategy was also a political strategy, the main weapon of which became emancipation at the end of 1862. Emancipation struck at not only the war-making potential of the Confederacy but also the heart of the Southern social system.
Concept note-2: -We often associate the Civil War with the end of slavery-and for good reason. But Lincoln’s primary goal in going to war was to save the Union, slavery or not. The Emancipation Proclamation changed the equation.
Concept note-3: -The strategy for the United States was to surround the territory of the South in the Anaconda Plan, blockading the Atlantic Ocean and controlling the Mississippi, to keep goods from going into or out of the South and forcing them to surrender.
