The following information is from Coyningham's book on the Irish Brigade (has been adapted slightly). Here he sketches out profiles of the officers of the 69th New York State Volunteers from 1861 until the wars end.
GENERAL ROBERT NUGENT - Post-civil war brevet-Colonel and Captain 16th Infantry, U. S. A., formerly major and Lieutenant-Colonel of the 69th New York Volunteers, was a native of Kilkeel, county Down; was in all the battles of the Brigade, except Antietam, when he was absent, sick, until Fredericksburg, when he was wounded by a rifle ball in the groin, his pistol, which was shattered, saving his life; was Acting Assistant Provost-Marshal-General of New York for a considerable period, during which he administered a dangerous and important office with dignity and honour. He commanded the Irish Brigade after General Meagher's resignation. He was a very dignified commander and an officer of high executive ability and undoubted gallantry.
LIEUTENANT-COLONEL JAMES KELLY - He was also a Captain of the 16th Infantry, U. S. A., was a native of Monaghan; was with the regiment up to the battle of Antietam, when he commanded and led the 69th in their famous charge. Here he received two wounds in the face and shoulder.
On the consolidation of the regiment, June, 1863, he was ordered to join his regiment in the regular army, and was subsequently in command of the recruiting depot at Grand Rapids, Michigan, from which at this post he was transferred to his old command as Lieutenant Colonel. He then commanded the Brigade for a short period, at the end of which he rejoined his regular command, and served with renewed distinction and popularity under Sherman in his famous campaigns. No braver or more efficient officer could be found in the service.
LIEUTENANT-COLONEL JAMES E. McGEE - He succeeded Colonel Kelly, and commanded two brigades of the First Division, Second Corps, for a considerable period during the most active preliminary movements of Grant's campaign, until he was honourably discharged after three years' service, and on account of wounds received at Petersburg, Virginia, June 16, 1864.
Colonel McGee was born in 1830, near the village of Cushendall, in the county of Antrim, Ireland; and was educated at St. Peter's College. Between 1847 and 1848, he was sub-editor of the "Nation", and secretary of a Confederate club. After the failure of the Young Ireland movement he emmigrated to the United States, and was for several years connected with the Irish American Press. He finally joined the volunteer service of the United States; commanded Company F, 69th until 1865, when, after reorganizing the regiment, he was commissioned Lieutenant Colonel.
Colonel McGee was very popular in the army, on account of his agreeable, social, manly demeanour; for gallantry and great executive ability and military tact, he had few superiors.
LIEUTENANT-COLONEL JAMES J. SMITH - He was for a long period the adjutant of the " Old Sixty-ninth," entered into active service with that command in the early months of the rebellion. He was with the Brigade in that capacity in every engagement, except Fredericksburg, when he was absent, detailed on recruiting service. Colonel Smith was a fine executive officer, and remarkable for coolness, intrepidity, and almost excessive modesty. He was promoted Lieutenant-Colonel, February 16th, 1865. He was a native of Monaghan.
MAJOR JAMES CAVANAGH - He was popularly known as " the little Major;' he was a native of Tipperary, and a gallant soldier. He was severely wounded at Fredericksburg, and was obliged to resign after that disastrous battle.

He subsequently joined the 69th New York Volunteers as surgeon, and became popular in the Brigade, both as a clever surgeon and polished gentleman. The doctor was frequently under fire, and on three occasions a prisoner, but was immediately released. He was principally engaged as operator, brigade surgeon, or in charge of hospitals.
DR. JAMES PURCELL - (whose father, Dr. Purcell, of Henry-street, New York-a native of Carrick-on-Suir, Tipperary-had to emigrate to this country on account of his connection with the '48 business), was born in Ireland, and after taking out his diploma, joined the Irish Brigade as assistant-surgeon, with which he served all through the war. He was a great favourite, and a young man of much promise in his profession.

After being exchanged, he joined General Meagher, as Captain in the 69th, amongst whose officers he was beloved, and served in every hard-fought battle in which the green flag was borne against the enemy. He was wounded at the battle of Malvern Hill, but had again taken command of his company before the evacuation of Harrison's Landing. He was a thoroughly brave young officer, of the most cheerful disposition and unblemished reputation, who would feel a stain deeper than a wound. He fell at Antietam, while bravely leading on his company. His remains were interred in the Catholic Cemetery at Frederick.
CAPTAIN FELIX DUFFY - commanding Company G, 69th, was a brave and experienced officer, and had already served his adopted country in the Mexican war, receiving the strongest marks of approbation from his commanding officers. He was for many years connected with the First Division of New York State Militia, and for some time before the breaking out of the rebellion held the post of Captain of Co. G., 69th Regiment N. Y.

A soldier, almost by instinct, he accompanied the Sixty-ninth Regiment, under Colonel Corcoran, to Virginia at the outbreak of the rebellion, and at the first battle of Bull Run was wounded in the right hand. When the Irish Brigade was commenced, he at once joined its ranks, and served with his regiment all through the desperate struggles in which it has borne so distinguished a part.
