Irregular warfare would be waged west of the Mississippi as it had been earlier against the Abenakis, Cherokees, Shawnees, Muskogees, and even Christian Indians. In the Civil War, these methods played a prominent role on both sides. Confederate regular forces, Confederate guerrillas such as William Quantrill, and General Sherman for the Union all engaged in waging total war against civilians. The pattern would continue in US military interventions overseas, from the Philippines and Cuba to Central America, Korea, Vietnam, Iraq, and Afghanistan. The cumulative effect goes beyond simply the habitual use of military means and becomes the very basis for US American identity. The Indian-fighting frontiersmen and the "valiant" settlers in their circled covered wagons are the iconic images of that identity. The continued popularity of, and respect for, the genocidal sociopath Andrew Jackson is another indicator. Actual men such as Robert Rogers, Daniel Boone, John Sevier, and David Crockett, as well as fictitious ones created by James Fenimore Cooper and other best-selling writers, call to mind D. H. Lawrence's "myth of the essential white American"—that the "essential American soul" is a killer.
