In 1975, Helmut Pemsel attempted to evaluate naval battles in history by a scoring system. He assigned a score to each of four aspects of a battle as follows; Numbers involved (1-4), Strategic Significance (0-2), Tactical Execution (0-2) and Political Significance (0-1). According to him, the largest naval battle ever is the Battle of Leyte Gulf at 8 points total, and six others tied for second at 7 points: Salamis, Aegates Is., Actium, La Hogue, Trafalgar and Jutland.
