The brigade was commanded at the Battle of Gettysburg by Brigadier General Samuel K. Zook, a pioneer in telegraphy and a militia officer from Pennsylvania. Zook was mortally wounded at the beginning of the attack into the Wheatfield on the afternoon of July 2nd. General Zook is honored by a monument on the south side of Wheatfield Road at the site where he was wounded.
