Home State: Pennsylvania

Unit: 1st Delaware Infantry


Before the Antietam Campaign:
Born into a prominent and historic Philadelphia family, he entered the University of Pennsylvania (as had his father and grandfather before him) in 1828, graduating in 1832. He briefly studied Law, served as a civil engineer for 2 years in Pennsylvania and Virginia, and returned to Philadelphia and the law. In 1837 he passed the bar and worked for the District Attorney. He obtained military experience in the mid-1840s as a member of two local militia companies--the National Grays and the Cadwalader Grays.

As the First Delaware was being reorganized from a three-month to three-year unit in October 1861, Hopkinson was elected Lieutenant Colonel. He was with the regiment as they were posted to Fort Monroe and Suffolk, Virginia until the Brigade got orders for Maryland on 6 September 1862.

In the Antietam Campaign:
Passing through Washington, the First reached the Antietam on the 16th and were assigned to French's Division of the Second Corps. Hopkinson was in command of the Regiment at Antietam after Colonel Andrews relieved the wounded General Weber in command of the Brigade in action at the Sunken Lane on the 17th. Hopkinson was himself wounded in combat there.

The remainder of the War:
He resigned his commission 14 December 1862 and was discharged on a Surgeon's Certificate, but was again in service as Colonel of the Second Coal Regiment--the 51st Pennsylvania Infantry--in the Militia of 1863, which was called up by the Governor in response to the invasion of the North by the Army of Northern Virginia that summer.

After the War:
Oliver Hopkinson was long prominent in the Philadelphia legal establishment and died in that city of pneumonia at the considerable age of 93.
