Asian and Pacific theatre of World War I consisted of various military engagements that took place on the Asian continent and on Pacific islands. They include naval battles, the Allied conquest of German colonial possessions in the Pacific Ocean and China, and an anti-Russian rebellion in Russian Turkestan and an Ottoman-supported rebellion in British Malaya. The most significant military action was the careful and well-executed Siege of Tsingtao in China, but smaller actions were also fought at Bita Paka and Toma in German New Guinea. All other German and Austrian possessions in Asia and the Pacific fell without bloodshed. Naval warfare was common; all of the colonial powers had naval squadrons stationed in the Indian or Pacific Oceans. These fleets operated by supporting the invasions of German-held territories and by destroying the East Asia Squadron of the Imperial German Navy. Allied offensives Tsingtao Tsingtao was the most significant German base in the area. It was defended by 3,650 German troops supported by 100 Chinese colonial troops and Austro-Hungarian soldiers and sailors occupying a well-designed fort. Supporting the defenders were a small number of vessels from the Imperial German Navy and the Austro-Hungarian Navy. The Japanese Second Squadron consisted of 5 old battleships, 12 cruisers, 24 destroyers, 4 gunboats, 13 torpedo boats, a carrier, multiple support vessels, and 26 transports. This included 23,000 soldiers. The British sent two military units to the battle from their garrison at Tientsin, numbering 1,500, and the Chinese who were unoccupied by the Germans sent over a few thousand troops on the side of the Allies. The bombardment of the fort started on 31 October 1914. An assault was made by the Imperial Japanese Army on the night of 6 November. The garrison surrendered the next day. Casualties of the battle were 703 on the German side and some 3,600 prisoners of war; casualties on the Allied side were 2,066. One Allied protected cruiser was also sunk by a German torpedo boat and when defeat was certain, the Germans and Austro-Hungarians scuttled their squadron. Pacific One of the first land offensives in the Pacific theatre was the invasion of German Samoa on 29–30 August 1914 by New Zealand forces. The campaign to take Samoa ended without bloodshed after over 1,000 New Zealanders landed on the German colony, supported by an Australian and French naval squadron.
