Battle of Jutland
Beatty's battlecruiser group met the German battlecruiser force, led by Rear-Admiral Franz Hipper. The German advantage in range-finding, with better optics, was important, but the British cruisers were saved by the arrival of the four battleships. Since the battleships were better in both armor and firepower, Hipper was forced to turn away from the east and the main German force of battleships.
