From Moroni's America, p. xi:
When we read the Book of Mormon under the light Joseph and Oliver provided, we see it in a completely new way.
1. When we read the Testimony of the Three Witnesses, what were the witnesses testifying of? Read their testimony closely.
2. What additional things did these three men testify about? Oliver Cowdery, for example, wrote 8 letters about early Church history. Here's how he introduced them (from Letter VII, p. 4).
In Letter VII, Oliver described the location of the final battles of the Jaredites and the Nephites this way:
At about one mile west rises another ridge of less height, running parallel with the former, leaving a beautiful vale between. The soil is of the first quality for the country, and under a state of cultivation, which gives a prospect at once imposing, when one reflects on the fact, that here, between these hills, the entire power and national strength of both the Jaredites and Nephites were destroyed.
(Letter VII, p. 14) (emphasis added)
Notice that Oliver said this was a fact. It was not speculation, a guess, or a tradition of unknown origin. It is a fact that these final battles took place in New York.
