Since this battalion was a complete tactical unit, under command of its own field officer, it did not lose its identity on becoming a part of the garrison at the fort. Both its officers and men, sharing tours with the regulars, were carried on the rosters of the post for guard and fatigue duty; but for purposes of discipline and administration the battalion organization remained intact. The acting battalion staff was composed of Lieutenant D. Fuller, adjutant; Lieutenant Phillips, quartermaster; Lieutenant Horton, signal officer; Lieutenant Wing, commissary; and, until relieved on June 23rd, Lieutenant Rolfe, assistant surgeon. The officers of the volunteers also were called upon for the performance of many duties under post details: Major Frye served as president of the post council of administration, as presiding officer at garrison courts martial, and later as trial officer of the summary court; Lieutenant D. Fuller was appointed post treasurer and librarian; Lieutenant Totten was detailed as post adjutant and recruiting officer, as well as mustering officer for the regiment at large, the latter detail requiring many visits to the scattered stations of the command; for much of the time the signal system of the works was under the supervision of Lieutenant Horton, owing to the absence on detached service of Lieutenant Catlin, the regular signal officer; Captains Braley and Williamson, with Lieutenants D. Fuller, Phillips, Wing, Harrison, Nilsson, and Totten also served as members of general courts martial.
