House Undivided - The Story of Freemasonry and the Civil War. This book is by Allen Roberts and was published in 1976 by Macoy Publishing and Masonic Supply Co.   It has 356 pages and explains the Masonic role in the Civil War.  The brotherhood was confronted with a difficult conflict when the Civil War broke out in 1861.  Freemasons, both northern and southern, were forced to choose a side and go against the very foundation of the society of Freemasonry.   Despite all their differences, Masons continued to practice their principles of brotherly love and good will on the battlefield, thus proving that the men who joined under the order would not, under any circumstances, sever their bonds of Masonic unity.  Here is their story told by the famous Masonic author Bro. Allen E. Roberts.
