Quincy Adams Gillmore (February 25, 1825 – April 11, 1888) was an American civil engineer, author, and a general in the Union Army during the American Civil War. He was noted for his actions in the Union victory at Fort Pulaski, where his modern rifled artillery readily pounded the fort's exterior stone walls, an action that essentially rendered stone fortifications obsolete. He earned an international reputation as an organizer of siege operations and helped revolutionize the use of naval gunnery.

Early life and career[]

Gillmore was born and raised in Black River (now the City of Lorain) in Lorain County, Ohio. He was named after the president-elect at the time of his birth, John Quincy Adams.

He entered the United States Military Academy at West Point, New York, in 1845. He graduated in 1849, first in a class of 43 members. He was appointed to the engineers and was promoted to first lieutenant in 1856. From 1849 until 1852, he was engaged in constructing the fortifications at Hampton Roads in coastal Virginia. For the next four years, he was instructor of Practical Military Engineering at West Point and designed a new riding school.

Beginning in 1856, Gillmore served as a purchasing agent for the Army in New York City. He was promoted to captain in 1861.

Civil War[]

With the outbreak of the Civil War in early 1861, Gilmore was assigned to the staff of Brig. Gen.Thomas W. Sherman and accompanied him to Port Royal, Virginia. After being appointed as a brigadier general, Gillmore took charge of the siege operations against Fort Pulaski. A staunch advocate of the relatively new naval rifled guns, he was the first officer to effectively use them to knock out an enemy stone fortification. More than 5,000 artillery shells fell on Pulaski from a range of 1,700 yards during the short siege, which resulted in the fort's surrender after its walls were breached.

The result of the efforts to breach a fort of such strength and at such a distance confers high honor on the engineering skill and self-reliant capacity of General Gilmore. Failure in an attempt made in opposition to the opinion of the ablest engineers in the army would have destroyed him. Success, which in this case is wholly attributable to his talent, energy, and independence, deserves a corresponding reward. —New York Tribune

Although he was one of the best artillerists and engineers in the army he was not well-respected by his men.[1]

After an assignment in New York City, Gillmore traveled to Lexington, Kentucky, where he supervised the construction of Fort Clay on a hilltop commanding the city. He was then assigned to replace Maj. Gen. Ormsby M. Mitchel in charge of the X Corps after that officer's death from yellow fever. In addition, Gillmore commanded the Department of the South, consisting of North and South Carolina, Georgia and Florida, with headquarters at Hilton Head, from June 12, 1863, to May 1, 1864. Under his direction, the army constructed two earthen forts in coastal South Carolina—Fort Mitchel and Fort Holbrook, located in the Spanish Wells area near Hilton Head Island.

He commanded forces that occupied Morris Island, Fort Wagner, and Fort Gregg, and also participated in the destruction of Fort Sumter. On July 18, 1863, during the siege of Charleston, South Carolina, Gillmore launched a major assault on Fort Wagner. The troops who assaulted Ft. Wagner were comprised primarily of the 54th Massachusetts Regiment, which included only African-Americans in its complement. Gillmore had ordered that his forces be integrated and that African-Americans were not to be assigned menial tasks only, such as KP or latrine duty, but instead they were to carry arms into battle. They and their assault on Ft. Wagner were the subject of the 1989 Civil War movie Glory, which starred Morgan Freeman and Matthew Broderick. "So shortly after 6:30 p.m., on July 18, 1863, the Union Colonel Robert Gould Shaw (played by Matthew Broderick) readied the 600 men of the 54th Massachusetts regiment for an assault on Ft. Wager. Shaw was the 25 year old son of Boston abolitionists, was white, as were all his officers. Again, all the regiment's enlisted complement were black, i.e. African-American." [from the History Net, African American History, 54th Massachusetts Regiment].

Although he does not received attribution for his command in the credits, the African American troops in the movie "Glory" were in fact under General Gillmore's command and were engaged in battle because of his orders ordering that they be allowed to do so. Prior that time, a 1792 law forbid African Americans from participating in the military, i.e., it forbid "persons of color from serving in the militia". However, his troops were unable to seize Charleston. In February 1864, Gillmore sent troops to Florida under the command of General Truman Seymour. Despite orders from Gillmore not to advance into the interior of the state, General Seymour advanced toward Tallahassee, the capitol, and fought the largest battle in Florida, the Battle of Olustee, which resulted in a Union defeat[2].

In early May, Gillmore and the X Corps were transferred to the Army of the James and shipped to Virginia. They took part in the Bermuda Hundred operations and played a principal role in the disastrous Drewry's Bluff action. Gillmore openly feuded with his superior, Benjamin F. Butler over the blame for the defeat. Gillmore asked for reassignment and left for Washington, D.C., On July 11, 1864, Gillmore organized new recruits and invalids into a 20,000-man force to help protect the city from a threat by 10,000 Confederates under Jubal A. Early, who had reached the outer defenses of the Union capital.

Gillmore was breveted as a major general of volunteers and a lieutenant colonel of engineers in the regular army. In mid-May 1865, Gillmore ordered all remaining slaves in the territory under his command to be freed; later that month he imposed martial law to enforce his orders.

With the war over, he resigned from the volunteer army on December 5, 1865.

Postbellum career[]

Gillmore returned to New York City and became a well known civil engineer, authoring several books and articles on structural materials, including cement. He was involved in the reconstruction of fortifications along the Atlantic coast (including, ironically, some that he had destroyed as a Union general). He served on the Rapid Transit Commission that planned the elevated trains and mass public transportation, as well as leading efforts for harbor improvements and coastal defenses. He was a prominent member of the University Club of New York.

His first wife died (date unknown for this post). He is reported to have married the widow of General Braxton Bragg, sometime after Bragg dropped dead in New Orleans in 1876. One of General Gillmore's sisters, Sophia, married a Civil War officer named Daniel Seth Leslie; Leslie was from the same area near Lorain, OH, as Gillmore. Three descendants of Daniel Seth Leslie were named in General Gillmore's honor, i.e. "Quincy Gillmore Leslie", his son "Quincy Charles Leslie" and his son, "Quincy Gilmore Leslie". In light of General Gillmore's association with African American troops under his command, Daniel Leslie was assigned some responsibilities for African American veterans after the Civil War. His name (Daniel Seth Leslie) is reported to appear on a monument to African American troops in the Washington, DC area.

Some African Americans carried the Gillmore and Leslie names forward. The Traveling Secretary for the Negro Leagues Kansas City Monarchs was named Quincy "J." Jordan Gilmore. (note the change from two LL's in Gilmore). He was nicknamed "Sect" and held that position from 1920–1925, with the Monarchs winning the Negro League World Series in 1924. He was born in Gary, IN, on June 29, 1882, died Feb 2, 1952. A baseball card has been published in his honor, by "Phil Dixon, 1987". Also, there are at least two contemporary (1990's to 2007) African American's named Quincy Leslie, one of whom is a Sergeant in the US Air Force.

General Gillmore died at Brooklyn, New York, at the age of 63. His son and grandson, both also named Quincy Gillmore, were also generals in the U.S. Army.

In memoriam[]

A coal schooner named in his honor, the General QA Gillmore, sank in 1881 in Lake Erie about 45 miles west of Lorain, near Kelley's Island. The shipwreck remains in the shallow waters of the lake.

A second ship was launched bearing his name, called the "Q. A. Gillmore". It was a steam powered tugboat "Hull #24" built for the Great Lakes Towing Company of Cleveland, Ohio, and launched around 1912-13. She also sailed on the Great Lakes and participated in rescues of ships in the famous and infamous Great Lakes storm of 1913. She was later sold and renamed the Reiss, which was a line of Great Lakes ore and commodity carriers, but which went out of business in the 1970s or so; one such ship was the Richard Reiss. The tug Q. A. Gillmore, now named the Reiss, is still afloat, anchored and located off of Tower Marine in Saugatuk, Michigan, and about 100 yards from the retired cruise ship S.S. Keewatin. Saugatuk is on the shores of Lake Michigan.

According to the owner of Tower Marine, R.J. Peterson of Saugatuk, as of the winter of 2007, her engines were still operational. The Reiss was owned by the Saugatuk Marine Museum and they donated the vessel to the Northeastern Maritime Historical Foundation of Duluth, Minnesota, sometime around May 2004. However, she is stuck in a mud bank out in the harbor and has not moved in recent years.
