This James F Gibson photograph of June 1862 is from the Library of Congress. Pictured left to right are: Lt. Henry Clay Meinell, Captain Horatio Gates Gibson, Lt. Edmund Pendleton, and Lt. William Duncan Fuller. The first three were together at Antietam in September that year.

Taken in New Orleans in 1867, this photograph was sold by J. Mountain Antiques of Ashburnham, MA. Pictured, left to right, are 1st Lt. Ballard S. Humphrey, Sgt. John B. Charlton (guidon, Battery K), Capt. William Montrose Graham, 2nd Lt. Charles King (son of Gen. Rufus King), 1st Lt. John J. Driscoll.

At Antietam, Humphrey was First Sergeant of Battery I and Graham was Captain of Battery K.

This fascinating map is found in the 1895 Annual Report to stockholders of the New York Central and Hudson River Railroad Company, Horace John Hayden, Second Vice President. It’s online as a PDF from Terry Link on his Canada Southern Railway (once part of Cornelius Vanderbilt’s 19th Century railroad empire) website.

Horace Hayden was two years out of Harvard and First Lieutenant of Battery L, 3rd United States Artillery at Antietam in 1862, but was rubbing shoulders with robber barons twenty years later.

Credited to Matthew Brady, this 1864 photograph is in the collection of the Library of Congress, and is labeled

Petersburg, Va., vicinity. Maj. Thomas T. Eckert (seated, left) and others of U.S. Military Telegraph Corps

Major Thomas Thompson Eckert was General McClellan’s chief of telegraphic operations on the Peninsula and Maryland Campaigns of 1862, later Chief of the Military Telegraph Office at the War Department and Assistant Secretary of War, and, much later, President then Chairman of the Western Union Telegraph Company, to 1910.

At left here is brevet Lieutenant Colonel and AAG Robert Hampton Ramsey (1838-1876), of General George Thomas’ staff, previously of the 45th Pennsylvania Militia, and on the right a very tired-looking Captain Edward Henry Leib, former First Defender from Pottsville, PA and brevet Major, 5th United States Cavalry.

This is late 1865 and Leib is probably still recovering from a gunshot through his body received at Five Forks, VA on 1 April. Captain Leib was at Antietam in September 1862 and in more than 100 other actions during the war.

His Army career ended in disgrace in 1877, however, due to drinking and conduct unbecoming, related to a “severe and depressing domestic affliction” – unpleasant assertions about his wife and “an affair of honor” with his commanding officer.

Frohne’s Historic Military sold this fine carte-de-visite photograph in about 2010; I found it on ancestry.com.
