When the war in Europe began in August 1914, Britain promptly requested Japanese assistance. On 15 August, Japan issued an ultimatum, stating that Germany must withdraw her warships from Chinese and Japanese waters and transfer control of its port of Tsingtao to Japan. The next day, Major-General Mitsuomi Kamio, General Officer Commanding (GOC), 18th Infantry Division, was ordered to prepare to take Tsingtao by force. The ultimatum expired on 23 August, and Japan declared war on Germany. At the beginning of hostilities, the ships of the East Asia Squadron under Vice Admiral Maximilian von Spee were dispersed at various Pacific colonies on routine missions. Spee's ships rendezvoused in the Northern Mariana Islands for coaling. SMS Emden then headed for the Indian Ocean, while the rest of the squadron made their way to the west coast of South America. The squadron engaged and destroyed a Royal Navy squadron at the Battle of Coronel, before being destroyed at the Battle of the Falkland Islands in the South Atlantic. The Boxer Rebellion at the beginning of the century had led Germany to consider the defense of Tsingtao. The port and town were divided from the rest of the peninsula by steep hills. The natural line of defense lay along the hills, from the Kaiserstuhl to Litsuner Heights. A second 17 km (11 mi) line of defense was set up along a closer line of steep hills. The final line of defense was along hills 200 m (660 ft) above the town. A network of trenches, batteries and other fortifications had been built in preparation for the coming siege. Germany had strengthened the defenses from the sea, laying mines in the approaches to the harbour and building four batteries and five redoubts. The fortifications were well equipped (though some with obsolete Chinese artillery) and were well manned. On 27 August, the Imperial Japanese Navy (IJN) sent ships under Vice-Admiral Sadakichi Kato, flying his flag in the pre-dreadnought Suwo, to blockade the coast of Kiaochow. The British Royal Navy (RN) strengthened the Japanese fleet by sending the China Station's pre-dreadnought HMS Triumph and the destroyer HMS Usk. According to a German press report after the siege, the Triumph was damaged by the German shore batteries. The blockading fleet consisted mainly of nearly obsolete warships, though it did at times include a few modern vessels. These included the dreadnoughts Kawachi, Settsu, the battlecruiser Kongō, her sister Hiei, and the seaplane carrier Wakamiya, whose aircraft became the first of its kind in the world to attack land and sea targets. These Japanese aircraft would also take part in another military first, a night-time bombing raid.
