Quote Investigator found no supporting citation for Mark Twain — nor for Shakespeare, Wilde or Churchill. The oldest documented relative is a line of narration in an 1866 novel; the earliest version in the modern joke shape ran in Walter Winchell’s column on 12 December 1928, where the punch line was credited to vaudeville comedian Frank Fay. The genesis of the gag itself appears to be anonymous.

“Mr. Fay, is this going to be a battle of wits?” “If it is,” was the indifferent retort, “you have come unarmed!”
1928 · nearest documented ancestor
As transcribed by Quote Investigator from Walter Winchell’s column in the Lexington Herald, 12 December 1928. Winchell frames it as Frank Fay’s retort during a sharp disagreement with an interior decorator.
1866 — the oldest known relative is not a joke but a line of narration: “A battle of wits was to be fought, and the Boy in Blue was unarmed to-night,” on page 236 of a Civil War novel published under the byline “Mrs. C. H. Gildersleeve” (full 1866 scan, Internet Archive ↗).
1928 — the first version in the modern joke shape: Walter Winchell’s widely distributed column of 12 December 1928 credits the retort to comedian Frank Fay (Quote Investigator ↗).
1929–1952 — the gag keeps mutating in print: a Richmond review of A. A. Milne’s Meet the Prince, a Toronto Goblin exchange, a 1938 Gumps comic strip, a 1941 military-academy paper playing “half-armed” against “half-wit”, and Joey Adams’ Joke Book in 1952 (the full chronology ↗).
Twain’s name never appears. Quote Investigator reports no supporting citations for Shakespeare, Twain, Wilde or Churchill, and Wikiquote’s Twain page carries no entry for the line in either its sourced or its misattributed lists (Wikiquote: Mark Twain ↗).
No copyright status can honestly be asserted for the popular one-sentence wording, because it has no identified first publication — it is an anonymous, evolving gag. Its two documented antecedents are long out of US copyright: Longstreet’s 1866 novel, which the Internet Archive lists as not in copyright ↗, and a December 1928 newspaper column — but neither carries this exact sentence.

This is a textbook quotation-magnet line: short, mean, quotable, and pinned on whichever famous wit the poster reaches for first. Quote Investigator checked all four of the usual candidates and found nothing behind any of them.

The wording on this pageMark Twain Most common
Circulated endlessly in aggregator form — usually as “Never have a battle of wits with an unarmed person” — with no book, letter, speech or interview attached; the Goodreads entry ↗ credits Twain and cites nothing, under the site’s own note that community quotes are unverified. Quote Investigator calls the Twain attribution unsupported ↗, and Wikiquote’s Twain page does not list the line at all.
✕
The “I would challenge you…” formWilliam Shakespeare Also claimed
Attached to Wilde the way most orphaned epigrams are, and equally unsupported ↗ — no citation in his plays, essays, letters or recorded conversation has been produced.
✕
All variantsWinston Churchill Quotation magnet
Also unsupported ↗. Worth noting that the earliest documented instance in the modern joke form is not a parliamentary exchange at all but a backstage quarrel between an American vaudeville comedian and an interior decorator.
✓Quote Investigator’s conclusion is that the jest “has numerous variants, and it has been evolving for many years”, with an apparently anonymous genesis — reasonably credited to Abby Buchanan Longstreet for an early example of the idea and to Frank Fay for an instance close to modern versions (Quote Investigator ↗).
Context
Why this one sticks to Twain
The line is a workhorse insult: it only lands if the person delivering it is famously quick, so the internet supplies a famously quick person. Mark Twain is the default choice — along with Shakespeare, Wilde and Churchill, the four names that absorb more orphaned one-liners than anyone else. None of them is in the record.
What the record shows instead is a joke being assembled slowly, in print, by people nobody remembers. It starts in 1866 not as a joke at all but as narration in a Civil War novel; it turns into a stage retort in 1928; and it keeps mutating for decades afterwards through theatre reviews, comic strips, a military-academy paper and a comedian’s joke book. The famous names arrive last, and without citations.
It evolved in print for decades, and Twain’s name is nowhere in the record.
The chain of variants, 1866 to 1952
1866 — narration, not a gag: “The blood swung its reddest pennant out over the boy’s cheeks, but Trissilian’s mood was not to be resented, or resisted. A battle of wits was to be fought, and the Boy in Blue was unarmed to-night.” (page 236 of the 1866 scan ↗)
1927–1952 — the “half-wit” pun in a Pennsylvania paper (1927); Frank Fay’s retort in Winchell’s column (1928); a Richmond review of A. A. Milne’s Meet the Prince and a Toronto Goblin exchange (1929); a New York Times film review (1937); the Gumps comic strip (1938); a 1941 military-academy paper trading “half-armed” against “half-wit”; an El Paso college column (1951); and Joey Adams’ Joke Book (1952).

1891–1961 · American vaudeville comedian & stage actor
Frank Fay (born Francis Anthony Donner, 1891–1961) was an American vaudeville comedian and stage and film actor, often described as the first stand-up — a performer who worked the audience directly rather than through a sketch. In the 1920s he was vaudeville’s highest-paid headliner, and he later created the role of Elwood P. Dowd in Harvey on Broadway. He is also remembered as the first husband of Barbara Stanwyck; Walter Winchell’s gossip column, where this retort surfaced in 1928, was exactly the sort of place his off-stage quarrels ended up.
