Bean was appointed as the official war correspondent with the AIF Troops in September of 1914. He was given the rank of Captain in the AIF and was able to follow the Australian infantry campaigns for the war. Bean landed with other troops at Anzac Cove at 10am on 25 April 1915 and remained on the peninsula for most of the campaign. When the AIF moved to Europe, Bean followed and would survive the war.
Bean’s volumes were published between 1920 and 1942 and can be found in the Ballarat Library Non-Fiction Area to be loaned out. The Australian War Memorial website also has digital copies that can be downloaded as PDF versions.https://www.awm.gov.au/histories/first_world_war/
