On June 19, 1820, he married Rebecca Wilson, also of Williamson County. The next year he joined his father and his brother John on the Missouri frontier west of Old Franklin. There he met William Becknell and became involved in the early Santa Fe trade. Hardeman was in the Meredith Miles Marmaduke expedition to New Mexico in 1824-25. He and Becknell trapped beaver along the Colorado River north and west of Santa Cruz and Taos and narrowly escaped starvation during the winter of 1824–25. On his return trip to Missouri, he lost two horses and a mule to Osage Indian attackers, but his overall trading profits must have been considerable. He was able to finance the Santa Fe trading trip of William Scott in the summer of 1825. Several years later he endowed Hardeman Academy at Hardeman's Cross Roads (later Triune), donated lands to Wilson's Creek Baptist Church, and opened a tavern and store, all in Williamson County, Tennessee.
A few years after his return to Tennessee he moved from Williamson to Hardeman County. In the fall of 1835 he and his brothers Thomas Jones and Blackstone Hardeman and his sister Julia Ann Bacon, together with their families, numbering about twenty-five people in all, moved to Texas. Bailey and several other members of the family quickly joined the independence movement. Bailey's first involvement was to help secure an eighteen-pound cannon at Dimmitt's Landing near the mouth of the Lavaca River and haul it to San Antonio, an action that encouraged Gen. Martín Perfecto de Cos to surrender his forces, on December 10, 1835. On November 28, while Hardeman was on the artillery assignment, the General Council of the provisional government appointed him to serve on a commission to organize the militia of Matagorda Municipality.

After the fall of the Alamo, Hardeman fled eastward with other cabinet members as the ad interim government moved from Washington to Harrisburg, and from Harrisburg to Galveston Island, in advance of approaching Mexican troops. The group reached Galveston in safety around the time of the battle of San Jacinto; after the Texas victory, Hardeman left the island to deliver supplies to the soldiers of the republic. As acting secretary of state he negotiated and signed two treaties, an open document honorably ending the war and providing for removal of Mexican soldiers from Texas, and a secret agreement in which Mexican general Antonio López de Santa Anna promised diplomatic recognition of the new republic. Hardeman was then appointed to go to Mexico City in order to help secure ratification of the open treaty.
His service to the republic was cut short by his death from congestive fever, probably on September 25, 1836, at his Matagorda County home on Caney Creek. He was buried there, but in 1936 his remains were moved to the State Cemetery in Austin. Bailey was survived by his wife and four children.
