Oliver H. Trester

(1836 - 1862)

Home State: Indiana

Branch of Service: Cavalry

Unit: 3rd Indiana Cavalry

Before Antietam

A 25 year old farm worker on his father's place in Washington Township, Dearborn County, he mustered as Private, Company D, 3rd Indiana Cavalry on 22 August 1861.

On the Campaign

He was mortally wounded in action near Middletown, MD on 13 September 1862.

A mile from our camp of the night before [in Frederick] the enemy was in these [Catoctin] mountains waiting for us. They greeted us with a battery posted in a mountain pass.

The Third Indiana counted off by fours and the dismounted men crawled up the mountainside through bushes and over stone fences, and soon made it too hot for that battery to operate. In this fight Oliver H. Trestor, of Company D, was killed as he leaped a stone wall right into a bunch of confederates in hiding behind it.

The rest of the War

He was admitted to a US Army hospital in Frederick, MD later that day with a gunshot to his lungs but died the next day, 14 September 1862. His body was taken home by relatives.
