During the Mexican-American War, he again volunteered, serving as the quartermaster from 1846 to 1848, and as an aid to General Zachary Taylor at the battle of Buena Vista. Upon returning from the war, Naper was again elected into the Illinois House of Representatives for one term, 1853 to 1854, representing DuPage County. In 1860, he was a merchant in Naperville and owned $35,000 in real property, with a personal estate of $5,000. Naper was also a Mason and was a founding member of the Naperville lodge. Naper died in 1862, leaving behind his wife Almeda.
