Troubridge’s cruiser squadron is pursuing the Goeben, a German battlecruiser, and the Breslau, its cruiser escort. Troubridge’s only chance of defeating the mighty Goeben is to catch it before it is fully light. But he does not get close enough. As the day brightens he decides to break off the pursuit, as German battlecruiser would annihilate his light ships if they can see clearly enough to fire.
The British have no idea where the Goeben and Breslau are going. They send ships to defend the Suez Canal and to block the Germans from heading west, unaware that Admiral Souchon’s intention is to reach Constantinople.
