The collection includes two diaries, for 1864 and 1865. In the 1864 diary, Dean tells of directing and supervising men in erecting and operating sawmills and building storehouses, hospitals, bridges, etc. around Lookout Mountain and Chattanooga. He also writes of the move from there to the siege of Atlanta and the occupation of Atlanta; of deserters, prisoners, destruction of railroads, regimental inspections, and camp life in general; and of the return march to Chattanooga in six and one-half days. The 1865 diary (Jan.-June), kept while he was in Chattanooga, tells about the weather, building barracks, duties, social activities, the surrender of Lee, death of Lincoln, and mustering out. Also includes miscellaneous citations, commissions, legal documents relating to his military service and his work as regent, and a statement (notarized by Dean) of Victor C. Vaughan pertaining to the Douglas-Rose dispute, 1878.
