Reisinger received his country's highest award for bravery during combat, the Medal of Honor, for actions taken on July 1, 1863 during the Battle of Gettysburg.

At age 2, the family moved to Venango County, Pennsylvania, and worked as farmers, lumberers, and blacksmiths.

The 150th engaged a large Confederate advance near the McPherson house, and here Reisinger was shot a second time, in the right leg.

After his recovery, Reisinger was assigned to Company B of the 14th Reserve Corps, and then served as an officer in the 114th Regiment Infantry U.S.
