“We’ll win this war… by fighting and showing the Germans we’ve got more guts than they ever will have. We’re not just going to shoot the sons-of-bitches, we’re going to rip out their living Goddamned guts and use them to grease the treads of our tanks.”

Not from pussyfeet meowing while ISIS beheads Americans — but shouted June 5, 1944 by Gen. George S. Patton.

Following best-sellers “Killing Lincoln,” “Killing Kennedy,” “Killing Jesus,” Bill O’Reilly’s newest killer, published later this month, is “Killing Patton: The Strange Death of World War II’s Most Audacious General.”

Former history teacher who’s covered wars, seen every WWII front, was in Berlin when the Wall came down, O’Reilly says: “Wartime things exist of which we have no idea. Our side wasn’t all good. Eisenhower and Patton, who had mistresses, were glory seekers, not buddies. In this book they’re human beings.”

About the thrilling finale, Hitler’s minute-by-minute final existence in the bunker: “Researcher Martin Dugard and I didn’t just read published works. We saw accounts of those who were actually there. Words spoken to us or written privately such as Hitler’s secretary to the grandchildren.

“Hitler’s clerks verified his last days with vivid portrayals in German. We talked with them. Learned his crazy hour-by-hour situation. Like cocaine eye drops? Living eyewitnesses even talked of romances in concentration camps.

“We searched. Went to grass-roots. Visited local historians. Traveled to Germany, Luxembourg. Examined everything. Besides nitpicking, our scholarship cannot be challenged. After the process of proofing it repeatedly, I’m comfortable. Three scholars have independently checked it.”

Those who experienced WWII or saw George C. Scott play “Old Blood and Guts” in the movies will be stunned at this ultimate reveal. Prologue is Dec. 21, 1945, U.S. Army Station Hospital in Heidelberg. Epilogue: The ultimate Chapter 28 is set in the morgue. Conclusion? General George C. Patton was murdered.

“We spent considerable time on Patton’s death. The truck carrying him turned left. Why? We walked that road. No reason for any left turn.

“We’ve re-examined WWII’s best general being poisoned. His final moments can’t be examined or explained. I’m not conspiratorial, but documents surrounding it have disappeared. I hope the Army or Pentagon reopen the case.”

Heroic Patton was not laid to rest in West Point “surrounded by soldiers for eternity,” but buried in Hamm, Luxembourg’s American Military cemetery. Page 309: “Neither Gen. Eisenhower nor President Truman attends.”

Says O’Reilly the Energizer Billy, who personally picks each book topic, “You can’t understand how brutal war is.”
