"The Death of Moroni -

I have found only one account which speaks of Moroni's death:

At a meeting at Spanish Fork, Utah Co., in the winter of 1896, Brother Higginson stated in my presence that Thomas B. Marsh told him that the Prophet Joseph Smith told him (Thomas B. Marsh, he being then President of the Twelve), that he became very anxious to know something of the fate of Moroni, and in answer to prayer the Lord gave Joseph a vision, in which appeared a wild country and on the scene was Moroni after whom were six Indians in pursuit; he stopped and one of the Indians stepped forward and measured swords with him. Moroni smote him and he fell dead; another Indian advanced and contended with him; this Indian also fell by his sword; a third Indian then stepped forth and met the same fate; a fourth afterwards contended with him, but in the struggle with the fourth, Moroni, being exhausted, was killed. Thus ended the life of Moroni. (Evans)"
