Churchill was born in Woodstock, Vermont, the son of Joseph and Sarah (Cobb) Churchill. Educated in the schools of his home town, he became a journalist, and published, in 1808, a weekly newspaper, "The Vermont Republican." Churchill married Lucy Hunter (1786–1862), daughter of William and Mary (Newell) Hunter, August 30, 1812, in Windsor, Vermont.
At the outbreak of the War of 1812, he was appointed 1st Lieutenant, 3rd U.S. Artillery on March 12, 1812, and was promoted to captain on August 15, 1813. He transferred to 1st U.S. Artillery on June 1, 1821, promoted to Major, 3rd U.S. Artillery, on April 6, 1835, and Colonel and Inspector General on June 25, 1841. He received the rank of brevet brigadier general, to date from February 23, 1847, in recognition of his services under General John E. Wool, at the Battle of Buena Vista during the Mexican-American War. At the beginning of the American Civil War, he had been Inspector General of the Regular Army for 20 years.
