Siege of Tsingtao
The Siege of Tsingtao, fought from 27 August to 7 November 1914, was the principal land engagement involving Japanese forces during the First World War, pitting a combined Anglo-Japanese expeditionary force against the German garrison defending the leased territory of Tsingtao (modern Qingdao) in China.[1][2] Commanded by Major General Mitsuomi Kamio, the Japanese 18th Division—comprising approximately 23,000 infantry supported by 142 artillery pieces—landed in early September and methodically advanced under cover of naval gunfire from British and Japanese warships, including the seaplane carrier Wakamiya, which conducted the conflict's first aerial reconnaissance and bombing raids.[3][2] The outnumbered German defenders, numbering around 4,000 under naval captain Alfred Meyer-Waldeck, relied on fortified positions such as Bismarck Hill and Hui-ch'üan Point, scuttling their warships and mounting a determined resistance that inflicted disproportionate casualties before surrendering on 7 November, yielding nearly 5,000 prisoners.[1][3] This operation, initiated at Britain's request to neutralize the German East Asia Squadron's base, marked the first joint British-Japanese military campaign and expelled Imperial Germany from its Pacific foothold, though Japan later leveraged the victory to assert expanded influence in China.[2][3]
