What is the Union War strategy?

Answer 1

The Union Strategy, formulated at the start of the war by veteran Mexican War General Winfield Scott, became known as the Anaconda Plan. The plan consisted of blockading the Atlantic and Gulf ports of the Southern States, and seizing control of the Mississippi River Valley, preventing the South from receiving supplies from foreign countries, or from the Western States that sided with the South. It counted on the slow strangulation of the South's ability to wage war, with the possibility of forcing the South to the conference table to negotiate peace. In the event, Grant also captured the Cumberland Valley and the Tennessee Valley to further split the South, and Sherman's total warfare March to the Sea destroyed the South's ability to make war by preventing its armies in the field from receiving ammunition, uniforms, or food, forcing Lee to surrender because his army no longer had the materiels with which to fight or rations enough for a week.
