Actually, the stories a bit flipped. It was Cowedery then went about accusing JS, so the council confronted him and gave him the boot.
Partially true, and oversimplified. Cowdery and others, David Whitmer and Warren Parish notably, mounted a public campaign against Smith and Rigdon, one feature of which was the opposition to polygamy. Oddly, according to the
Encyclopedia of Mormonism, Cowdery had initially been enthusiastic about the polygamy ordinance when Smith revealed it unto him, but evidently had a bad experience with it and later came to oppose it. That according to the Mormon source, take it as you will.
Cowdery accused Smith of having a “dirty, nasty, filthy affair” with Fanny Alger, who had been a sort of live-in maid in the Smith household. He called Smith’s new teachings (polygamy?) “disorganized doctrines” and referred to the few Smith loyalists remaining as “hot headed power seeking, ignorant men.”
Unfortunately for Smith and his few friends, Cowdery, the Whitmers, and others who’d been excommunicated for their muckracking activities, did not leave the area, but remained there, continuing to make trouble. This led to the formation of what came to be known as the Danites, a covert brotherhood that was also known as the “Destroying Angels.”
When the dissenters rode to another county seeking help against threats made (in writing) by the Destroying Angels against them, the Angels went to their homes and turned their wives and children out into the wilderness, destitute. They confiscated all of their property, including clothing, furniture, and personal possessions. Nice guys, those Destroying Mormons.
Kind of makes you think that the Mormon prophet didn’t cotton to criticism, don’t it?
