...Southern Confederacy, lead in the main by the renowned General Robert E. Lee, most definitely did not apply the Fabian strategy of warfare…

There’s a high cost to the Fabian strategy.

Both Livy and Polybius mention that Hannibal was using “devastation” to draw his Roman opponent into frontal battle — following the ancient Greek example (standard tactic was to arrive before harvest season and despoil crops — and anything else they could lay hands on — to get the opposing side to offer battle).

People of Lee’s class were well educated in the classics; I’m sure he had this “devastation” in mind when deciding not to follow a Fabian strategy. And this assumes that Lee had control of overall strategy, which he did not until mid 1862 — and he’d been called ‘Granny’ Lee for hesitating to follow through on a frontal attack a year previous.

Towards the end of the war, the South had clearly lost, but refused to concede. To lever them into surrendering, we see Sherman’s “March to the Sea”, the destruction from which must have played into Lee’s choice to not fight on after Appomattox.
