John Baillie McIntosh
John Baillie Mcintosh was born on June 6, 1829, at Fort Brooke, Florida (the site of Tampa), where his father, a Regular Army officer later killed in the Mexican War, was stationed. He was the brother of the Confederate brigadier, James M. Mcintosh, and great-grand-nephew of the Revolutionary general who killed Button Gwinnett, causing his signature to become the highest priced of all autographs of a signer of the Declaration of Independence. During the war with Mexico John served aboard the U.S.S. Saratoga as midshipman, resigning from the navy soon after to reside in New Brunswick, New Jersey, where he engaged in business with his father-in-law. In 1861, feeling that his brother's defection to the Confederate cause constituted a blot on the family honor, he reentered the service of the United States as a second lieutenant of the 2nd (Regular) Cavalry. He compiled a most distinguished record from the beginning of the war until the last shot was fired. He was brevetted major in the Regular Army for services during the Peninsular campaign under George B. McClellan in 1862; and after taking part in the Maryland campaign against General Robert E. Lee, he was made colonel of the 3rd Pennsylvania Cavalry on November 15, 1862. Upon the reorganization of the cavalry of the Army of the Potomac in the spring of 1863, Mcintosh was assigned a brigade under Alfred Pleasonton and fought at Kelly's Ford and during the Chan-cellorsville operations in May. Following Gettysburg, William W. Averell, his former division commander, pronounced him the inferior of no officer in command of a cavalry brigade in Federal service. In May, 1864, after recuperating from injuries received when his horse fell with him, he resumed command of his brigade. At the battle of Winchester in September, 1864, he received the wounds which necessitated the amputation of his right leg. For his gallantry in this battle he won the brevet of brigadier in the Regular Army. Commissioned major general by brevet in both the regular and volunteer services at the end of the war, he became lieutenant colonel of the 42nd Infantry in 1866 and was retired in 1870 as a brigadier general. Thereafter General Mcintosh made his residence in New Brunswick, where he died on June 29, 1888, and was buried in Elmwood Cemetery.
