Acker served as Minnesota’s State Adjutant General before the war.  He raised a company for the 1st Minnesota Regiment before resigning his position in order to accept a commission as Captain of Company C.  His gallantry at Bull Run was noted by President Lincoln, who commissioned him Captain in the regular army after he resigned from the 1st Minnesota due to a quarrel with Colonel Gorman.
