In August 1914 Admiral Sir David Beatty devised a plan to draw the German Navy into a major sea battle. Beatty used two light cruisers, the Fearless and Arethusa and 25 destroyers to raid German ships close to the German naval base at Heligoland. When the German Navy responded to the attack, Beatty brought forward the battleships, New Zealand and Invincible and three battlecruisers. In the battle that followed, the Germans lost three German cruisers and a destroyer. The British ship, the Arethusa was badly damaged but was towed home to safety. Beatty's aggressive tactics at Heliogoland helped developed his reputation and was a factor in the decision to make him Commander of the Grand Fleet in place of Sir John Jellicoe in December, 1916.
