The whole City of the great Salt Lake is stired up and packing up for leaving [as the U.S. army advances]. ...
I presented before the meeting [of the Presidency andn Council of Twelve] the case of O. Pratt who did not believe in some of the teachings of President Young and thought Presidet Young had reproved him unjustly. The subjet was discused at length by the Twelve and President Young. Much instruction was given. At the Close Orson Pratt Confessed his faults and said that He would never teach those principles again or speak them to any person on the Earth. We all forgave him and voted to receive him into full fellowship.
[The church eventually adopts Pratt's views over Young's.]
