• Brannan led a group of Latter-day Saints to California aboard the ship Brooklyn and later traveled with a small group of men eastward in 1847 and met the Brigham Young Pioneer Company on the banks of the Green River in what is now southwestern Wyoming to attempt to convince him to bring the main body of the Saints to California.

  Young tasked him with continuing a small distance east to meet up with the sick detachments of the Mormon Battalion to lead them back to California to be mustered out and receive their pay. It was later decided that he would just lead them them to the Salt Lake Valley and from there continue on to California with the leader of that branch of the Battalion who would collect their pay and bring it back to the Valley. Brannan remained in the Valley for only a very short time before he went back to California and settled there with his family.
