A lot of the great, easy to think of ones, have already been taken. I’ll throw in the book, and especially movie of, “Lone Survivor.” Great story of bravery, that didn’t happen at all the way it was portrayed in those two works. See, e.g., Ed Darack’s, Victory Point, ( Amazon.com ) for the more tragic, prosaic details of how Operation Red Wings happened.
Benjamin Franklin discovering electricity.
This side of the pond it’s a well known fact, and demonstration of insularity, that the local newspaper in Aberdeen reported the Titanic sinking as “Aberdeen man lost at sea”.
Really funny story.
Except it didn’t.

Reminds me of the Gordian Knot.
And it finally triggered a favorite event of my own that maybe never happened: there was this small kingdom in ancient Mesopotamia where the royal astrologers saw signs that their king was going to die. So they had the king temporarily abdicate his throne and appointed a court gardener named Enlil-bāni to be king in his place. When the time of crisis was past, Eeby was supposed to step down so that the old king could return to the throne. Except the old king choked to death while the gardener was on the throne, and Enlil-bāni went on to be king for 24 years. (The king was apparently real, but the way he became king may have been retconned to make him seem more like “one of the people”, sort of like Sargon of Akkad, who had a suspiciously familiar origin story.)
But that’s what they called it at the time. Because the battle was over who had control of it.
That is your favorite? 
You like it? :dubious:
The Merovingian kings were descended from Jesus and Mary Magdalene. As a matter of fact, all the clues shown in The Da Vinci Code.
The shootout at the O.K. Corral did not take place at the O.K. Corral.
He never claimed that, he just found out that Lightning was electricity, thus he invented Lightning Rods.
My Fave is the story of Alfred the great and the Burned cakes.
Not impossible but very likely a myth.
It happened, on 9/24/2016:
Memphis 77, Bowling Green 3
King Canute defying the waves.
Not to mention Trump being exonerated by the Mueller Report.
Walter Raleigh bringing the potato to Europe.

the 2nd Gulf of Tonkin attack in Vietnam , the first one was real
A good example of the thread topic. Theodore Roosevelt did give a lot of support to the national park system but he certainly didn’t establish it. Yellowstone was the first national park and it was founded in 1872, when Roosevelt was just fourteen years old.
The Book Of Mormon narative, including the Jews who became the Indians and Christ visiting the Americas.
Grew up believing that completely.
And Charles Napier didn’t really send “Peccavi” as a report.
My favorite was a birthday promise made by an old girlfriend. It certainly would have been historic!
