The Long-Knives 2: Sabers West

At war’s end, Guy Dubose -- owning no skill except soldiering -- joined up with the U.S. Army, donning the same Yankee blue he'd been lining up in his rifle sights for the last five bloody years. Quartered with society's lowliest at Fort Linden, the unreconstructed Rebel found himself in a whole other kind of shooting match, this time on the wild Texas frontier. But fighting was fighting, be his opponent Bluebelly or R*****n, and where the gunsmoke was the thickest was where Guy DuBose aimed to be.
For Fort Linden’s commander, Captain Gordon Blackburn, however, the lives of a few insignificant Johnny Rebs was a small price to pay for a seat behind a Washington desk. Either Sergeant DuBose and his misfits would earn their Captain a hero's reputation -- or they'd end up watering down the Texas dust with their blood!
