Civil War historian E. Merton Coulter wrote that for those who would secure its independence, "The Confederacy was unfortunate in its failure to work out a general strategy for the whole war". Aggressive strategy called for offensive force concentration. Defensive strategy sought dispersal to meet demands of locally minded governors. The controlling philosophy evolved into a combination "dispersal with a defensive concentration around Richmond". The Davis administration considered the war purely defensive, a "simple demand that the people of the United States would cease to war upon us". Historian James M. McPherson is a critic of Lee's offensive strategy: "Lee pursued a faulty military strategy that ensured Confederate defeat".
