Spear entered the Union Army in August, 1862, as a Captain of Maine volunteers, many of whom he personally recruited. He was promoted to Colonel, and from October, 1863 to February, 1865, commanded a regiment in the Army of the Potomac. Serving in several commands, Ellis Spear left the Army July, 1865 with the rank of Brigadier General.
Thereafter he was employed by the U.S. Patent Office, becoming assistant commissioner in 1874 and Commissioner in 1877. He resigned in 1878.
Though a friend of Chamberlain’s during the Civil War, he differed with his interpretation of the great struggle. The differences dampened their friendship creating a very public between the two.
After he left the Patent Office, he practiced as a patent attorney in Washington until past the age of 80. Spear died in Washington, D.C. on April 3, 1917 and was buried in Arlington National Cemetery.
