There were four main parts to the Anaconda Plan, which, incidentally, was a very sound military strategy by the North to win the war. The problem was, it would take four years for them to achieve the four parts, when they should have been able to finish it much earlier.
Part 1 called for blockading the South with the Union navy, preventing them from selling cotton to England or getting needed war materials from other countries.
Part 2 called for occupation of the entire length of the Mississippi River, denying the South its only waterway for transportation and splitting the South effectively in two.
Part 3 called for a drive through the Shenandoah Valley into Georgia and to the ocean, splitting the South yet again.
The final part called for the occupation of the capital city of Richmond, and with it, the Confederate government.
