This photograph of the Minnesota First Infantry Volunteer Regiment's officers was taken in 1862. From left to right(back row): Cpt. Wilson B. Farrell, Lt. Samuel T. Raguet, Lt. Charles Zierenberg, Cpt. Louis Muller, and Cpt. Henry Coates. Colonel Mark Downie is seated. Muller and Zierenberg were both mortally wounded at the Battle of Cemetery Ridge on the first day of Gettysburg, and Farrell was killed the next day during Pickett's charge, leaving Coates as the only man pictured to avoid death or major injury in the war. Downie was the first wounded officer to return to command that October, after surviving two wounds to his right arm, a bullet through his left foot, and shell damage to his left lung at Gettysburg.
