The Ancient Art of War at Sea is a computer game developed by Brøderbund and released for IBM micros and compatibles in 1987 as a sequel to The Ancient Art of War.
The player commands a fleet of ships in this naval-combat simulation which takes place in the mid-19th century. The player faces one of five historic opponents, each of which employs a different strategy against the player: the Duke of Medina Sidonia (1588); Blackbeard (1718); John Paul Jones (1779); Horatio Nelson (1805); and a fictitious opponent Thor Foote.
