The monument to Perrin’s Brigade is southwest of Gettysburg on the west side of West Confederate Avenue. (West Confederate Avenue – Pt. 2 tour map) The brigade was commanded by Colonel Abner Perrin, a South Carolina lawyer and Mexican War veteran.
The brigade was under Perrin’s command as senior colonel while its assigned commander, Brigadier General Samuel McGowan, recovered from a wound from the Battle of Chancellorsville. The brigade is often (and properly) called “McGowan’s Brigade.”
