Alma 21:11-14

11 Therefore, when he saw that they would not hear his words, he departed out of their synagogue, and came over to a village which was called Ani-Anti, and there he found Muloki preaching the word unto them; and also Ammah and his brethren. And they contended with many about the word.

12 And it came to pass that they saw that the people would harden their hearts, therefore they departed and came over into the land of Middoni. And they did preach the word unto many, and few believed on the words which they taught.

13 Nevertheless, Aaron and a certain number of his brethren were taken and cast into prison, and the remainder of them fled out of the land of Middoni unto the regions round about.

14 And those who were cast into prison suffered many things, and they were delivered by the hand of Lamoni and Ammon, and they were fed and clothed.

I have a feeling there is a LOT that is not mentioned here. "Suffered many things" leaves the imagination wondering.
