Before Antietam

He was appointed Colonel of the 90th on it's organization in September 1861 as a 3-year unit, having just completed service in command of the same Regiment in 90-days' service. It had then been known as the 19th.

On the Campaign

" At daylight of the 17th the battle was opened by the Third Brigade, and the Ninetieth was sent to the support of Matthews' Battery. When the Third was overcome and driven back, the Second, to which the regiment belonged, and to which it had now returned, relieved the Third, and remained in action until its ammunition was exhausted, when it was withdrawn. It was later in the day sent to the extreme right to cover the Hagerstown Road, where Colonel Lyle was placed in command of the brigade, Lieutenant Colonel Leech assuming command of the regiment. The loss in this battle was ninety-eight. Colonel Lyle, Captain Charles F. Maguire, and Lieutenants Samuel W. Moore, Anthony Morin and James M. Moore were among the wounded."
(from Bates)

The rest of the War

He served periodically as Brigade Commander as senior Colonel, and as Division commander briefly in May 1864. He was honorably mustered out of the service with his regiment in November 1864. He was honored by brevet to Brigadier General of Volunteers on 13 March 1865 for his war service.
