Lorenzo Thomas (October 26, 1804 – March 2, 1875) was a career United States Army officer who was Adjutant General of the Army at the beginning of the American Civil War. After the war, he was appointed temporary Secretary of War by President Andrew Johnson, precipitating Johnson's impeachment.
Thomas was born in New Castle, Delaware. He graduated from the United States Military Academy in 1823, and was commissioned a second lieutenant in the 4th U.S. Infantry. He fought in the Seminole War in Florida and, during the Mexican-American War, he was the chief of staff to General William O. Butler. He received a brevet promotion to lieutenant colonel for Monterrey, which was made permanent in 1852. From 1853 to 1861, he served as chief of staff to the commanding general of the U.S. Army, Winfield Scott.
Just before the start of the Civil War, Thomas was promoted to colonel and adjutant general of the U.S. Army on March 7, 1861. On August 10, 1861, President Abraham Lincoln appointed Thomas a brigadier general in the regular army, to rank from August 3, 1861, the date Lincoln sent the nomination to the U.S. Senate for confirmation. The Senate confirmed the appointment on August 5, 1861.Camp Thomas, a Regular Army training base in Columbus, Ohio, was named in his honor in July 1861. He held the position of adjutant general until he retired in 1869, except for a special assignment to recruit African-American troops in the Military Division of the Mississippi from 1863 to 1865.
