see his Battle Report

Before Antietam

He enlisted in Company A of the 5th New York Heavy Artillery on 29 November 1861 at New York City for three years service. He mustered as First Lieutenant on 2 December, and was promoted Major of the Regiment on 7 March 1862.

On the Campaign

He supervised artillery operations at Harpers Ferry on the Campaign, and was captured there with the rest of the garrison on 15 September 1862. According to the Colonel's aide Lieutenant Binney, the Major was among the few mentioned by Colonel Miles "upon his death-bed" for his actions there:

Major H. B. McIlvaine, chief of artillery, was also mentioned as deserving much credit for bravery, and for his cool and firm manner of placing batteries under the galling fire of the enemy on Camp Hill and other places, where the most danger existed, encouraging the artillerists.

The rest of the War

After being exchanged he returned to service, and was promoted briefly to Lieutenant Colonel, serving from 2 February to 7 March 1863, but that appointment was "revoked", and he mustered out at the rank of Major 16 Dec 1864 at Harpers Ferry at the end of his term of service.

After the War

Sometime after his son Harry was born in 1870, "H.B." moved to Minnesota, and by 1880 he was living and farming in Faribault, Rice County.
