Thomas Marsh’s Interview with
David Whitmer and Oliver Cowdery, 1838
Source: “History of Thomas Baldwin Marsh [by himself],”
Millennial Star 26 (1864)
After making preparations I started from Far West  and moved three miles out of town, ostensibly for the purpose of settling, and soon moved off to Clay County, and from thence to Richmond, Ray County, where I saw David, John and Jacob Whitmer and Oliver Cowdery, who had all apostatized.
I inquired seriously of David if it was true that he had seen the angel, according to his testimony as one of the witnesses of the Book of Mormon. He replied as sure as there is a God in heaven, he saw the angel according to his testimony in that book. I asked him, if so, why he did not stand by Joseph? He answered, in the days when Joseph received the Book of Mormon, and brought it forth, he was a good man and filled with the Holy Ghost, but he considered he had now fallen. I interrogated Oliver Cowdery in the same manner, who answered similarly.
