This is Nathaniel Grant's Oath of Loyalty to the United States. Grant, a 48-year-old resident of Clay County, Missouri, says that he felt "a little sorry" when Gen. Sterling Price captured Gen. Mulligan's army at Lexington, Missouri, and that he felt "rather down in the mouth" when the Federal army was defeated at Bull Run in 1861. The oath, labeled No. 52 in a bound volume, was signed by Nathaniel Grant in 1866.
