John P. Sheahan on commission as lieutenant, Virginia, 1864
John P. Sheahan of the 1st Maine Cavalry wrote to his parents in Dennysville to tell them about the reaction to his commission as a 1st lieutenant. He had been studying for exams to be promoted.
He decided to leave the 1st Maine Cavalry in part because of the way he was treated by the captain. When the captain heard about Sheahan's commission, he ordered him held in the guard house. The captain told the Adjutant that he intended to have Sheahan court martialed for "a good many things."
The adjutant advised the captain that he would be hurting himself if he proceeded with his plans. Sheahan was released.
