At the beginning of the US Civil War, the South's two main strategies were to protect the entire Confederacy from Union attacks. In 1862, Confederate President Jefferson Davis, announced that this strategy was not effective and the South did not have enough troops to carry on in that manner. He then explained that the new strategy would be to defend specific and vital parts of the South, thereby using their troop strength more effectively. As another component of this was to take advantage of any opportunities to invade Northern states and thus bring pressure on the North who were insulated from the war's destruction.
