Explanation:

  He was born in Ireland and then moved to the U.S. as an adult. He enlisted in the army and served during the Civil War but did not see almost any action.  He then gathered former Union Army veterans to serve as auxiliaries of the Republican Party in the Reconstruction of America.

  He joined with some friends from that movement and with Murphy´s connections they achieved securing military contracts to give supplies to the Apache Reservation.
