Battle of Helgoland Bight

The first major naval action in the North Sea, the Battle of Helgoland Bight, took place on 28 August 1914. Helgoland was again stationed off Wangerooge. Despite her proximity to the battle, Helgoland was not sent to aid the beleaguered German cruisers, as she could not be risked in an unsupported attack against possibly superior British forces.

However, Beatty's task force nearly ran headlong into the entire High Seas Fleet. At 06:20, Beatty's destroyer screen came into contact with the German torpedo boat V155. This began a confused, 2-hour battle between the British destroyers and the German cruiser and destroyer screen, often at very close range. At the time of the first encounter, the Helgoland class battleships were less than 10 nautical miles (18.5 km) away from the six British dreadnoughts; this was nearly within firing range, but in the darkness, neither British nor German admirals were aware of the composition of their opponents' fleets. Admiral Ingenohl, aware of the Kaiser's order not to risk the battle fleet without his express approval, concluded that his forces were engaging the screen of the entire Grand Fleet, and so, 10 minutes after the first contact, he ordered a turn to the southeast. Continued attacks delayed the turn, but by 06:42, it had been carried out. For about 40 minutes, the two fleets were steaming on a parallel course. At 07:20, Ingenohl ordered a further turn to port, which put his ships on a course for the safety of German bases.

By 23:30, the High Seas Fleet had entered its night cruising formation. The order had largely been inverted, with the four Nassau-class ships in the lead, followed directly by the Helgolands, with the Kaisers and Königs astern of them. The rear was again brought up by the elderly pre-dreadnoughts; the mauled German battlecruisers were by this time scattered. At around midnight on 1 June, the Helgoland- and Nassau-class ships in the center of the German line came into contact with the British 4th Destroyer Flotilla. The 4th Flotilla broke off the action temporarily to regroup, but at around 01:00, unwittingly stumbled into the German dreadnoughts a second time. Helgoland and Oldenburg opened fire on the two leading British destroyers. Helgoland fired six salvos from her secondary guns at the destroyer Fortune before she succumbed to the tremendous battering. Shortly after, Helgoland shifted fire to an unidentified destroyer; Helgoland fired five salvos from her 15 cm guns to unknown effect. The British destroyers launched torpedoes at the German ships, but they managed to successfully evade them with a turn to starboard.

In the course of the battle, Helgoland had fired 63 main battery shells, and 61 rounds from her 15 cm guns.

Later actions

After the Battle of Jutland, Admiral Scheer argued that the fleet could not break the British naval blockade, that only the resumption of unrestricted U-boat warfare would be successful. As a result, the High Seas Fleet largely remained in port, with the exception of two abortive sorties in August and October 1916. In April 1917, Helgoland accidentally rammed the new battlecruiser , which was in the process of fitting-out, as she left her berth. In October 1917 Helgoland, in company with , went to Amrum
