All the following groups, which aided the Union effort, were minor compared to the quality of intelligence provided by black slaves. There were Union sympathizers who were members of the following groups: Orders of the Heroes of America, the Peace and Constitutional Society, organized in Arkansas; and the Peace Society, which existed in Alabama, East Tennessee, Georgia, Mississippi, and perhaps even Florida that furnished the majority of intelligence that were verified by the network of northern spies that infiltrated the South. These groups consisted of Catholic, Methodist, Quakers, Jewish and other religious groups with relatives in the north where they funnelled the intelligence.
