Jacob Ammen was born on January 7, 1806, in Botetourt County, Virginia, but his parents moved north and he grew up in Ohio and was then appointed to the U. S. Military Academy. After being graduated from there in the class of 1831, he remained in the army only until his resignation in 1837. He served two tours of duty at the Academy as an instructor, was present in Charleston Harbor in 1832-33 during the nullification proceedings, and taught mathematics at various colleges in Kentucky, Indiana, and Mississippi. He reentered Federal service as captain of a company of the 12th Ohio six days after the bombardment of Fort Sumter. During the early part of the war he participated, as colonel of the 24th Ohio, in the western Virginia campaign and later in the battle of Shiloh and in the subsequent siege of Corinth. He was promoted to brigadier general of volunteers on July 16, 1862, having mainly administrative duties in garrison commands and courts-martial. He resigned on January 14, 1865, to become a surveyor and civil engineer before settling on a farm near Beltsville, Maryland, in 1872. He was a member of the board of visitors to the Military Academy and was also deputed by the Secretary of the Navy to accompany the Isthmus of Panama commission to examine canal routes. In 1891 General Ammen removed to Lockland, Ohio, where he died on February 6, 1894. He is buried in Spring Grove Cemetery, Cincinnati.
