While living in the St. George/Dixie mission in the 1860s while the U.S. Civil War was ongoing, Eliza Ann Haven Westover noted that:
There was barely time to pay
attention to the happenings in the rest of the country, but it would hardly be
avoided. We were at war with ourselves, although Utah was not yet a state we
still we affected by the Civil War. Our Prophet Joseph had had a prophecy in
1832 that this unrest would come and tear the country apart. Some neighbors
were for it, some were not. But many of us were familiar with the prophecy and
felt a reverence that this too would result in blessing coming out of
challenges. All were against slavery that was the one difference in this Dixie.
This area was called Dixie because it had a climate similar to the Southern
Dixie, and we grew cotton and sugar beets. We even grew mulberry trees for silk
worms all without the use of slaves. (Kaylene Canfield, A Life Worthy of Imitation:
Eliza Ann Haven Westover [2007], 31)
This shows that Latter-day Saints who believe that the U.S. Civil
War (1861-1865) was a partial fulfillment of D&C 87. However, contra some critics (e.g., Trent Horn; Norman Geisler), it was not teaching that the Civil War
itself would spread all over the world and be the beginning of a worldwide
conflict.
