At the session held in Brooklyn in 1862, great interest was manifested in the vespers, then a novelty, that were arranged by Samuel Longfellow. This meeting was marked by its glowing patriotism, that rose to a white heat. A sermon of great power was preached by Dr. Bellows, interpreting the duty of the hour and the destiny of America. The resolutions and the discussions were almost wholly along the lines of patriotic duty and devotion suggested by the sermon. At the last of the Autumnal Conventions, held in Springfield, Mass., October 13-15, 1863, the sermons were preached by Rev. Edward Everett Hale and Rev. Octavius B. Frothingham, while the essays were by Professor Charles Eliot Norton and Rev. James Freeman Clarke. The Autumnal Conventions came to an end, probably in part because the civil war was more and more absorbing the energies of the people both in and out of the churches, and partly because the desire for a more efficient organization had begun to make itself felt. In the spring of 1865 was held the meeting in New York that resulted in the organization of the National Conference, the legitimate successor to the Autumnal Conventions. [Sidenote: Influence of the Civil War.] During the period of the civil war, Unitarian activities were largely turned in new directions. Unitarians bore their full share in the councils of the nation, in the halls of legislation, on the fields of battle, in the care of the sick and wounded, and in the final efforts that brought about emancipation and peace. At least fifty Unitarian ministers entered the army as chaplains, privates, officers, and members of the Sanitary Commission.[14] The Unitarian Association also directed its attention to such work as it could accomplish in behalf of the soldiers in the field and in hospitals. Books were distributed, tracts published, and hymn-books prepared to meet their needs. Rev. John F.W. Ware developed a special gift for writing army tracts, of which he wrote about a dozen, which were published by the Association. As the war went on, the Association largely increased its activities in the army; and, when the end came, it had as many as seventy workers in the field, distributing its publications, aiding the Sanitary Commission, or acting as nurses and voluntary chaplains in the hospitals. The end of the war served rather to increase than to contract its labors, aid being largely needed for several months in returning the soldiers to their homes and in caring for those who were left in hospitals.
