Oliver Cowdery was uniquely qualified to write about the Book of Mormon.In 1835, he wrote a letter describing the Hill Cumorah, in New York, as the scene of the final battles of the Nephites and Lamanites.  His series of eight letters were written with the aid of Joseph Smith and served as a response to the first anti-Mormon publication “Mormonism Unvailed” by Eber D. Howe and released in Oct 1834.Letter 1 was canonized in the Pearl of Great Price as a footnote to the Joseph Smith History. “These were days never to be forgotten - to sit under the sound of a voice dictated by the inspiration of heaven…”            (— Letter from Oliver Cowdery to W.W. Phelps (Letter I), (September 7, 1834). Published in Latter Day Saints' Messenger and Advocate, Vol. I. No. 1. Kirtland, Ohio, October, 1834.)Letter VII was the second to the last in the series and was Oliver's inspired answer to those who are uncertain about the location of Cumorah.Oliver's letter—Letter  VII— is  one of the critical documents in early Church history. It was published several times while Joseph Smith was alive. Joseph even had his scribes copy it into his personal journal as part of his life history. It was accepted by every early LDS writer and leader.Reading and understanding Letter VII is a faith-affirming experience for those who accept the Book of Mormon as a literal history and as modern-day scripture and called "the most correct of any book."
