The Confederates eventually synthesized these various stands of strategic theory and political reality into what Davis called an "offensive-defensive" strategy. This consisted of defending the Confederate homeland by using interior lines of communication (a Jominian but also common-sense concept) to concentrate dispersed forces against an invading army and, if opportunity offered, to go over to the offensive, even to the extent of invading the North. No one ever defined this strategy in a systematic, comprehensive fashion. Rather, it emerged from a series of major campaigns in the Virginia-Maryland and Tennessee-Kentucky theaters during 1862, and culminated at Gettysburg in 1863. It almost emerged, in embryonic form, from the first battle of Manassas (Bull Run) in July 1861, a small battle by later Civil War standards but one that would have important psychological consequences in both the North and the South.
And yet they attempted exactly that - on more than one occasion.
