The news that the Seminoles had begun hostilities in Florida spread slowly early in January, 1836. The intelligence stirred the country, however. The War Department had heard of the Dade’ massacre and of other Indian atrocities as early as January 4, but it was not until January 17 that it received official verification of the battle of the Withlacoochee.
