The Official History of Australia in the War of 1914–1918 is a 12-volume series covering Australian involvement in the First World War. The series was edited by C. E. W. Bean, who also wrote six of the volumes and was published between 1920 and 1942. The first seven volumes deal with the Australian Imperial Force while other volumes deal with the Australian Naval and Military Expeditionary Force at Rabaul, the Royal Australian Navy, the Australian Flying Corps and the home front; the final volume is a photographic record.
Unlike other official histories which have been aimed at military staff, Bean intended the Australian history to be accessible to a non-military audience. The relatively small size of the Australian forces, enabled the history to be presented in great detail, giving accounts of individual actions that would not have been possible when covering a larger force. Bean devoted over to the Battle of Fromelles, a relatively small action intended as a diversion during the Battle of the Somme, which lasted one night and involved the 5th Australian Division. Fromelles was also the first time that the First Australian Imperial Force (AIF) saw action on the Western Front and was very costly for the Australians, with 5,533 men killed, wounded or captured.
The three volumes of the Official History of the Australian Army Medical Services, 1914–1918, mostly written by Arthur Butler, are also considered by the Australian War Memorial to be Volumes XIII, XIV & XV of the Official History.
Following the publication of the final volume, Bean compiled Anzac to Amiens, a condensed history in one volume aimed at the general public, which was published in 1946. This was followed in 1948 by Gallipoli Mission which detailed how he and his team had researched what had happened in Gallipoli.
