{{Main|Battle of Heligoland (1914)}}
''Invincible''{{'}}s first action was as part of the battlecruiser force under the command of [[David Beatty, 1st Earl Beatty|Admiral Beatty]] during the Battle of Heligoland Bight operation on 28 August 1914. Beatty's ships had originally been intended as distant support of the British cruisers and destroyers closer to the German coast in case large units of the [[High Seas Fleet]] sortied in response to the British attacks. They turned south at full speed at 11:35<ref group=Note>The times used in this section are in [[Coordinated Universal Time|UTC]], which is one hour behind [[Central European Time|CET]], which is often used in German works.</ref> when the British light forces failed to disengage on schedule and the rising tide meant that German capital ships would be able to clear the bar at the mouth of the [[Jade estuary]]. The brand-new light cruiser {{HMS|Arethusa|1913|2}} had been crippled earlier in the battle and was under fire from the light cruisers {{SMS|Strassburg||2}} and {{SMS|Cöln|1909|2}} when Beatty's battlecruisers loomed out of the mist at 12:37. ''Strassburg'' was able to duck into the mists and evade fire, but ''Cöln'' remained visible and was quickly crippled by fire from the squadron. But Beatty was distracted from the task of finishing her off by the sudden appearance of the elderly light cruiser {{SMS|Ariadne||2}} directly to his front. He turned in pursuit, but reduced her to a flaming hulk in only three salvos at a range under {{convert|6000|yd|m}}. At 13:10 Beatty turned north and made a general signal to retire.<ref name=m9>Massie, pp. 109–113</ref> At this time, ''Invincible'', trailing the main body of battlecruisers, opened fire on ''Cöln''. She fired 18 rounds, all misses,<ref>Tarrant, p. 33</ref> before Beatty's main body encountered the crippled ''Cöln'' shortly after turning north and she was sunk by two salvos from {{HMS|Lion|1910|2}}.<ref name=m9/>
