Missionary doesn’t make it to the mission field 

D&C 114:1-2; “Revelation through Joseph Smith, Far West, Missouri, April 17, 1838. History of the Church 3:23… that he may perform a mission unto me next spring, in company with others, even twelve including himself, to testify of my name and bear glad tidings unto all the world….”

History of the Church 3:170-1;Captain Patten then ordered a charge, which was instantly obeyed. The parties immediately came in contact, with their swords, and the mob were soon put to flight, crossing the river at the ford and such places as they could get a chance. In the pursuit, one of the mob fled from behind a tree, wheeled, and shot Captain Patten, who instantly fell, mortally wounded, having received a large ball in his bowels.”

Prophecy given in Far West, MO on April 17, 1838. 

Patten was one of the disciples.  Smith prophesied that Patten would go on a mission the next spring, but Patten was killed in a gun fight just 6 months later without being able to fulfill that prophecy.
