western lands

Explanation:

Most of the territory the United States acquired in the nineteenth century was located in "Western Lands."

Firstly, it was through the Louisiana purchase in 1803 from France, which cover the western half of the Mississippi, then span across the present state of Arkansas, Missouri, Iowa, Oklahoma, Kansas, and Nebraska; and a big part of North Dakota, South Dakota, etc.

Also, following a war with Mexico between 1846 to 1848, the United States gained further lands in the western territory which span from Kansas to California.

lee and grant, both of whom held the highest rank in their respective armies, had known each other slightly during the mexican-american war (1846-48) and began their dialogue by exchanging awkward personal inquiries. characteristically, grant had arrived in his mud-splattered field uniform while lee had turned out in full dress attire, complete with sash and sword.
