Give us some more information. What are you looking for? What makes you ask the question? Do you have evidence that there was action near Lyman? Roger Hanson of Hurley Miss. may have information since he is familiar with Civil war actions on the Mississippi Coast or Dr. Charles Sullivan, Professor Emeritus Mississippi Gulf Coast Community College, Perkinston, MS. They have the most documentation on the coast region. If you provide more information, we can help you connect to them directly.
