Frank on the Lower Mississippi

The narrative follows a young naval gunboat officer, Frank, who takes part in river operations after the fall of a key Confederate stronghold. He leads and joins shore expeditions, night raids, and scouting missions, often accompanied by his cousin Archie, and confronts guerrillas, rival spies, and sudden dangers. Episodes show him improvising as detective and commander, coping with setbacks, narrow escapes, and an unlucky flight, and ultimately receiving promotion and an honorable discharge. Action emphasizes youthful courage, leadership at sea and ashore, and practical problem-solving amid wartime riverine campaigning.
