The hatband on the cap worn by William G. Armstrong is marked with his name and regiment. A private in Company F of the 6th Iowa Cavalry, he is pictured here with his cavalry saber and revolver after his November 1862 enlistment. Armstrong was killed in action less than a year later in the Battle of Whitestone Hill, the final engagement in 1863 operations against the Sioux and other Indian nations in Dakota Territory.
