Hamilton Gamble was born in Winchester, Virginia, the youngest of seven children of Joseph and Anne Hamilton Gamble, Scots-Irish who immigrated to Virginia in 1784 from northern Ireland. Gamble studied at local schools and at age 13 went to Hampden-Sydney College, a Presbyterian seminary. He read the law with an established firm and by 1817 was accepted to the bar in Virginia.
Move to Missouri and Career
In 1818 as a young man of 20, he moved to St. Louis, Missouri to join his older brother Archibald Gamble, who had moved there earlier and was established as a clerk of the St. Louis Circuit Court. After practicing in Franklin in the middle of the state, Gamble became prosecuting attorney of the Circuit Court of Howard County, Missouri. In 1824, Governor Frederick Bates appointed him as Missouri Secretary of State and he moved to the capital, then located at St. Charles, Missouri. When the capital was moved to Jefferson City, Gamble returned to St. Louis in 1826, settling in what was the major city of the state. He set up a private legal practice there. Although a slaveholder, he at times represented slaves in court. He became a member of the American Colonization Society, which supported the resettlement of free blacks from the US to the new colony of Liberia.
Marriage and family
In 1827, Gamble married Caroline J. Coalter of Columbia, South Carolina. He likely met her when she was visiting St. Louis, as both her brother David Coalter and a sister lived there. Her sister had married attorney Edward Bates of St. Louis. In addition to representing some slaves in freedom suits, Bates later served as a judge and as US Attorney General under President Abraham Lincoln. Hamilton and Caroline had three children: Hamilton, David, and Mary Coalter Gamble.
Judicial and later career
In 1846, Gamble was elected to the Missouri Supreme Court by the Whig Party, the first justice from this party. He was quickly elected as chief justice, on a rotating term. Though a slaveholder, he dissented in the Missouri Supreme Court decision of the Dred Scott v. Emerson case. He supported the 28-year-old precedent set in the 1824 ruling of "once free always free" in Winny v. Whitesides. He maintained that Scott were free because he had been held illegally as a slave while resident in a free state. Gamble resigned his judgeship in 1855 due to failing health, and in 1858 moved to Pennsylvania.
Provisional Governor of Missouri
As the secession crisis deepened, Missouri attempted to follow a policy of armed neutrality, in which the state would not support either side in the war but remain in the Union. A special election in February established a Missouri Constitutional Convention to determine the relationship between Missouri and the United States. The convention voted against secession and affirmed the state's neutrality. The outbreak of hostilities at Fort Sumter led to unrest in Missouri. Secessionists seized the Liberty Arsenal a week later. Governor Claiborne Jackson called up the state militia for drill in St. Louis and to receive some arms clandestinely obtained from the Confederacy. This resulted in a confrontation with the aggressive Union commander Nathaniel Lyon, who forced the surrender of the militia, in what was called the Camp Jackson Affair. After a deadly riot ensued, the Missouri legislature authorized the reorganization of the militia into the Missouri State Guard, controlled by the governor. General William Harney reached an agreement with the new Missouri State Guard commander Sterling Price, known as the Price-Harney Truce. Lincoln appointed Lyon to replace Harney as Commander of the Department of the West. During negotiations among the governor, Lyon, and Price, Lyon would not accept the governor's proposed limitations on Federal troops and volunteers. The meeting ended abruptly with Lyon declaring, "This means war. In an hour one of my officers will call for you and conduct you out of my lines." As the Missouri government fled into exile, Lyon rapidly captured the capitol at Jefferson City, Missouri a few days later in mid-June 1861. The pro-Union members of the Missouri Constitutional Convention reconvened in July 1861 to consider the status of the state. The convention declared the governor's office and state legislative offices to be vacant and appointed Gamble as governor of a provisional government of Missouri on August 1. Gov. Jackson called a rump session of the pro-Confederate members of the General Assembly in Neosho, Missouri, and, in late October with a dubious quorum, passed an ordinance of secession. Although secessionists considered Gamble an unelected puppet of the Union forces, he opposed harsh Union treatment of the state. For instance, he protested to President Lincoln about the Fremont Emancipation, which unilaterally freed the state's slaves in 1861 and imposed martial law. Lincoln agreed to Gamble's request to overturn this decision, rescinded the emancipation, and removed John C. Fremont from command. Gamble died in office in 1864 after suffering complications from an infection of a broken arm. He is buried at Bellefontaine Cemetery in St. Louis.
