I Wilford Woodruff testify that about 7 oclock PM I discoverd a stream of light in the south west quarter of the heavens. The rays of Light were in the form of a Broadsword with the hilt downward the Blade raised pointing from the west south west raised to an angle of 45 degrees from the horizen & extending nearly or within 2 or 3 degrees to the zenith of the degree whare the sign appeared. This sign gradually disappeared from half past 7 & at 9 oclock immediately disappeared.
The following is the declaration of Joseph the Seer conserning the foregoing sign:
As sure as there is a God who sits enthroned in the heavens & as sure as he ever spoke by me So sure there will be a spedy & Bloody war & the broad sword seen last evening is the sure sign thereof.
