The wars of the 18th century produced a series of tactically indecisive naval battles between evenly matched fleets in line ahead, such as Málaga (1704), Rügen (1715), Toulon (1744), Minorca (1756), Negapatam (1758), Cuddalore (1758), Pondicherry (1759), Ushant (1778), Dogger Bank (1781), the Chesapeake (1781), Hogland (1788) and Öland (1789). Although a few of these battles had important "strategic" consequences, like the Chesapeake which the British needed to win, all were "tactically" indecisive. Many admirals began to believe that a contest between two equally matched fleets could not produce a decisive result. The tactically decisive actions of the 18th century were all chase actions, where one fleet was clearly superior to the other, such as the two battles of Finisterre (1747), and those at Lagos (1759), Quiberon Bay (1759) and Cape St. Vincent (1780).
