In June 1914, the annual summer cruise of the East Asia Squadron began; "Gneisenau" rendezvoused with "Scharnhorst" in Nagasaki, Japan, where they received a full supply of coal. They then sailed south, arriving in Truk in early July where they restocked their coal supplies. While en route, they received news of the assassination of Archduke Franz Ferdinand in Sarajevo. On 17 July, the East Asia Squadron arrived in Ponape in the Caroline Islands. Here, von Spee had access to the German radio network, where he learned of the Austro-Hungarian declaration of war on Serbia and the Russian mobilization. On 31 July, word came that the German ultimatum, which demanded the demobilization of Russia's armies, was set to expire. Von Spee ordered his ships be stripped for war.
