High Water Mark of the Rebellion Monument

The High Water Mark Monument is a Civil War memorial in Gettysburg, Pennsylvania, featuring bronze tablets mounted on a stone base. The tablets list military units that participated in the assault of 1863.

The site marks the furthest advance of Confederate forces at Gettysburg, where a crucial phase of the campaign unfolded. The assault in July 1863 ended with the Southern army's retreat, turning the tide of the war.

The memorial was funded by fourteen northern states working together to honor those who fought here. This shared effort reflects how deeply the battle shaped communities across the North.

The monument sits along Hancock Avenue and can be reached from designated parking spaces or via a walking path from the main battlefield parking area. Visitors can find it easily through the park's signage and can explore nearby memorials from this location.

The memorial is shaped like a large open bronze book with pages listing both Union and Confederate military formations in detail. This unusual design lets visitors discover the names and structures of both sides in a memorable way.
