The popular line has no known source. What Patton actually said was “may God have mercy on our enemies; they will need it.” He closed a lecture to his officers at Fort Benning with it in September 1940, and the line is printed in Martin Blumenson’s The Patton Papers, 1940–1945 (1974). His line is a boast that the enemy will need God’s mercy. The “because I sure as hell won’t” ending was added later and is not in that text.
“May God have mercy upon my enemies, because I sure as hell won't” Not George S. Patton's wording. His documented line, from a lecture to officers at Fort Benning in September 1940, is "may God have mercy on our enemies; they will need it" (Martin Blumenson, The Patton Papers, 1940–1945, 1974). No source is known for the "because I sure as hell won't" version.

Occasion
Patton’s first formal lecture to his officers, early September 1940 (Chapter 1, “Fort Benning: Brigade”)
This quotation expresses very exactly the goal we are seeking in this division. I know that we shall attain it and when we do, may God have mercy on our enemies; they will need it.
Fort Benning, September 1940
Patton ended his lecture on the German campaign in Poland with this line. Just before it, he recalls Caesar training his legions so well that “it was not necessary to give them orders.” Blumenson also uses “May God have mercy on our enemies; they will need it” as the title of Part I of the book.
On Wikiquote’s Patton talk page ↗, the popular line sits in the Unsourced list. An editor’s note there gives the genuine form, “May God have mercy on our enemies; they will need it,” and points to Blumenson’s The Patton Papers 1940–1945. The note dates that book 1972, but the volume’s own copyright page says it was first published in 1974.
In Blumenson’s The Patton Papers, 1940–1945 ↗, Chapter 1 quotes Patton’s September 1940 lecture to the officers at Fort Benning. It ends: “may God have mercy on our enemies; they will need it.”
The “mercy … for I will have none” formula is much older. American Heritage (October 1993) ↗ quotes Union general Joseph Hooker: “May God have mercy on General Lee, for I will have none.”

Fact-check
Where the popular version goes wrong
The popular version keeps Patton’s opening, “May God have mercy on … enemies.” It then adds a personal refusal of mercy that Patton’s documented line does not contain.

Aggregators repeat the line without a citation. Quotewise ↗, for example, lists “May God have mercy for my enemies because I won’t.” under Patton and shows no source. Wikiquote put the popular wording in the Unsourced list on its Patton talk page ↗.

The “mercy … I will have none” formulaJoseph Hooker, Union general in the U.S. Civil War Older parallel
American Heritage ↗ quotes Hooker saying “May God have mercy on General Lee, for I will have none.” HistoryNet ↗ also says Hooker “reportedly” said it. The Wikiquote talk-page note adds that Ken Burns’ The Civil War credits the line to Hooker. Hooker’s words have the same shape as the popular “Patton” ending, but no source we found shows that the Patton version was borrowed from him.
✓Patton’s documented words are “may God have mercy on our enemies; they will need it,” from his September 1940 lecture to officers at Fort Benning. They are printed in Martin Blumenson’s The Patton Papers, 1940–1945 ↗ (1974).
Context
Why the difference matters
The two versions say different things. In 1940, the United States was not yet at war and Patton was helping to build an armored division almost from nothing. His line was a promise about training: once the division reached the standard he described, any enemy facing it would need God’s mercy. It shows confidence in his men, not a pledge to be merciless.
The modern version makes the line about Patton himself refusing mercy, and that fits the “Old Blood and Guts” image better than the original does. Its refusal clause matches a much older boast credited to Civil War general Joseph Hooker. This is a common way misquotes form: a real line by a famous person is sharpened into a punchier one.
“…may God have mercy on our enemies; they will need it.”

George Smith Patton Jr. was a U.S. Army general. In World War II he commanded the Seventh Army in the Mediterranean, then the Third Army in France and Germany after the 1944 Normandy invasion. In 1940 he was at Fort Benning, Georgia, helping train the new 2d Armored Division. That is where he gave the lecture behind this quote. His blunt, profane manner makes him one of the internet’s favorite names to pin tough-sounding lines on.
