Weems' Life of General Francis Marion

Francis Marion (c. 1732 – February 26, 1795) was a military officer who served in the American Revolutionary War. Acting with Continental Army and South Carolina militia commissions, he was a persistent adversary of the British in their occupation of South Carolina in 1780 and 1781, even after the Continental Army was driven out of the state in the Battle of Camden.

Due to his irregular methods of warfare, he is considered one of the fathers of modern guerrilla warfare, and is credited in the lineage of the United States Army Rangers. (wiki)
This biography, though historically based, should not be considered factual. It is not that there was no such man — indeed there was, and other accounts indicate that Francis Marion is as deserving of praise as this account would indicate — or moreso. It is not that the events described did not take place — most of them, at least, did.
It is simply that Parson Weems (Mason Locke Weems, 1759-1825), in an honest effort to teach a high patriotism, nobility, and morality, sometimes embellished or exaggerated his stories to the point of falsehood, as with his invention of the cherry tree anecdote in his Life of Washington. It seems strange that such a devotion to moral teaching should use falsehoods to reach its audience, but he apparently felt the means justified by the end.
