The Battle of Gettysburg had already been raging for two days when the 66th Regiment of Ohio Volunteer Infantry got the order to step beyond the safety of their breastworks early on the morning of July 3, 1863. They were to enfilade the expected Confederate attack coming up Culp’s Hill. The order would leave the unit with their flank in the air and exposed to enemy counter attacks. Bravely the men left the safety of their lines as dawn swept the night’s darkness from the hill.

Their fire would pin down many Confederate troops after they began their assault, and with no opportunity to flee or advance many surrendered where they were. The 66th was instrumental in preventing a successful Confederate assault and helped to secure the right flank of the Union line.
