Joseph Smith and Sidney Rigdon were tarred and feathered
Joseph no question. According to contemporary Mormon accounts (most recorded in diaries), When Joseph appeared in church the next day, he was missing large clumps of hair, his skin was red and raw from scrubbing, and the right side of his head was blistered (from acid in the tar, not from heat). Sidney, on the other hand, looked no worse for wear and preached a sermon as though nothing had happened.
It is said that Eli Johnson demanded that the prophet be castrated, for he suspected Joseph of being too intimate with his sister, Nancy Marinda. But the doctor who had been persuaded to join the mob declined the responsibility at the last moment.
Other accounts insist that Joseph had been caught in the doing the deed in a haystack with Nancy. Many accounts also state that the barber surgeon was drunk (as were several members of the Mormon mob) to the point where they were afraid Joseph would be killed by the surgery. One can only imagine how different Mormonism would be today if Joseph were cut close and square, to use a term commonly used by the Danites.
Joseph survived the ordeal with injuries that healed over time.
Joseph would carry the scars on the side of his head from the acid in the tar for the rest of his life.
Tradition suggests that Smith may have married Marinda at this early time.
Married is the Mormon justification for adultery in general, and statutory rape in particular. In fact, it was about this time that Joseph and Sidney were writing down the words of D&C Sec. 51 (I think that's the one) prohibiting plural marriages.
A postscript to the Joseph and Nancy allegations ...
Another postscript: About a year later, Fanny Alger, a 16-year old orphan living with the Smith family, who was employed as a nanny and domestic servant, turned up pregnant with Joseph's baby. This time, Joseph was forced to marry the young lady until he could palm her off on another Saint. Fanny is widely regarded as the first of more than 30 concubines wedded to Joseph.
