Daniel B. Kaufmann was among the ten officers chosen by Colonel James Nagle in the summer of 1861 to help recruit volunteers to serve in what would become the 48th Pennsylvania Infantry. A resident of Port Clinton, Kaufmann had served under Nagle during the first three months of the war, as captain of the Port Clinton Artillery in Nagle's 6th PA Infantry. When the call thus went out again for volunteers, this time to serve for three years, Kaufmann had little difficulty in getting his artillerists (converted to infantry) to re-enlist. Additional recruits came from the townships of southern Schuylkill County, near the Berks County line, as well as Tamaqua. Most of his volunteers were canal laborers or boatman on the Schuylkill Canal; Kaufmann was himself a dispatcher. Mustered into service of Company A, 48th PA, on September 17, 1861, Kaufmann was then 29 years old, stood 5'9" in height, had a dark complexion, gray eyes, and black hair.
Captain Kaufmann faithfully led his company throughout the war's first three years, emerging unhurt from the various campaigns and battles. Then, on August 1, 1864, Captain Kaufmann was dismissed from service.
I cannot recall the circumstances that led to Kaufmann's dismissal, though I do know that that information is available at the Pennsylvania State Archives. I am thinking it may have had something to do with the fiasco at the Crater, since his dismissal came just two days after the explosion of the mine. I am not sure, however, so when next in Harrisburg, I will be sure to look it up.
