"Early in May, 1861, the writer belonged to the Howitzer Corps, Company D, 2nd N. Y. Militia, later known as 82nd N. Y. Our Captain was Thaddeus P Mott. We frequently drilled the howitzer in Tompkins Square, pulling the guns by ropes. When we arrived in Washington the war Department would not recognise a volunteer howitzer company, and the choice was given the men to be merged into one of the infantry companies or permanently detached from the regiment and organised as a battery of field artillery, Captain Mott selected the latter for the me. We were stationed at Chain Bridge, Va. We were finally designated the 3rd, N. Y. Independent battery, as 'Mott's Battey' and one of the famous Sixth Corps batteries to the end of the war."
