What were the union battle stratigies?

Answer 1

The Union used a strategy known as the Anaconda Plan, devised by General Winfield Scott in the early days of the war. His plan was to use the industrial might of the North to slowly strangulate the South. The Navy would blockade the Southern seaports, preventing them from selling cotton to buy supplies. This bought time for the North to raise and train an army, and give the South time to reverse its decision, when it saw how hopelessly outclassed it was in men and materiel. Once the army was raised, it would secure the river ports along the Mississippi Valley preventing the Confederate States in the West from effectively communicating with those in the East. With a few tweaks, and the addition of the Doctrine of Total War after 1863, and the further division of the Eastern Confederate States by Sherman's March to the Sea, this is the strategy that won the war for the Union.

Answer 2

The Anaconda Plan developed by Winfield Scott called for the blockade of Southern seaports to prevent the export of cotton and other raw materials, and the import of arms and other war materiel; and for the seizure of Mississippi river port towns to cut communications: to prevent the transfer of troops and supplies from the trans-Mississippi Confederate states, and deny Confederate forces the use of the Mississippi as a means of inland transportation. Grant added the Tennessee and Cumberland Rivers to the plan, and Sherman added the concept of Total War: to destroy the enemy's means of production of crops, manufacturing, and infrastructure, destroying the South's ability to wage war.
