Soldiers of the Army Sustainment Command invited Cub Scouts from Davenport, Iowa's Garfield Cub Scout Pack 19 to participate in the evening retreat ceremony, Oct. 1, at Rock Island Arsenal, Ill. The tradition of honoring the U.S. flag during an evening ceremony began in 1835 and is comprised of the sounding of "Retreat," the firing of the evening gun, followed by the playing of "To the Color" as the flag is lowered.
