After the Florida war, Bradford returned to Tennessee, where he was elected to a term in the
Tennessee State Senate in 1837. In 1839, he moved to
Holly Springs, Mississippi, where he set up a law practice and was the owner of the
Holly Springs & State Line Railroad Company. He was elected to the legislature, representing
Marshall County, Mississippi, in 1841 and again in 1852. In the
1847 gubernatorial election, he was defeated as the
Whig Party candidate for governor of Mississippi. In 1852, he lost a bid for the
United States House of Representatives. When the
United States declared
war against Mexico in 1846, Bradford heeded the call to arms and volunteered for the Mississippi
militia. On June 18, 1846, an election was held to determine who would be the commanding officer. Bradford received 350 votes.
Jefferson Davis was next with 300 votes. Bradford refused the election stating "no man should take command of this regiment without that full confidence." A second ballot was held and Davis was elected by a plurality of some 147 votes out of more than 900 ballots. Bradford was appointed major and served as third in command. During the
Mexican War, Bradford was conspicuous for bravery. Following the
Battle of Monterrey, Bradford recalled, "I was in all of the fight, saw everything and was exposed fifteen hours to cannon balls,
grape canister and
musketry, grazed seven times but escaped unhurt." At the
Battle of Buena Vista, both Col. McClung and Jefferson Davis had been wounded, which added to their glory and publicity. This was more than the fiery little Bradford could stand and he rushed up and down the lines, waving his arms in the air and exclaiming, "My God! Can't one bullet hit me?" At Buena Vista, Bradford was appalled when he thought the
Mississippi Regiment was retreating. Not having heard Davis' order to retire, Bradford was reported to have called out in a most excited manner, "Shoot me! … Ah, kill me! The Mississippi Regiment has run and I'll be damned if I want to live another minute!" Davis' order was transmitted to Bradford and shortly thereafter the Mississippi Regiment reformed and started an advance that carried the day. Jefferson Davis was highly appreciative of Bradford's military expertise. After Buena Vista, Davis reported: "To Major Bradford I offer my thanks for the prompt and credible manner in which he executed all the orders I gave him, and especially refer to the delicate duty assigned him of restoring order among the files of another regiment when rendered unsteady by the fire of the enemy's artillery." After the war, Bradford returned to Holly Springs. In honor of his
military service, the citizens of Marshall County, Mississippi, presented Bradford with a ceremonial sword which bears the names "Withlacoochee," "Monterrey," and "Buena Vista." In 1852, he moved to
Bolivar County, Mississippi where he established a plantation,
Bradford Place. In 1861, he was elected to the
Provisional Confederate Congress. After his term, Bradford did not seek reelection but was again elected to the
Mississippi Legislature in 1863 and 1864 representing Bolivar County. The end of the Civil War left Bradford impoverished, but he was able to recoup some of his losses by practicing law in Bolivar County. ==Personal life and death==
