Mark, Captain "Leary" is undoubtedly Capt. Frederick Lear, an ordnance officer in the District of Arkansas early in the war. His name is often misspelled as "Leary". I show him stationed at Des Arc in late April 1862. His Compiled Service Record is mis-filed as "Leary, Fredrick" in the microfilm of Confederate Staff Officers. He clearly signs his name "Lear".
