Gallipoli Mission can be found online here:Students of Gallipoli owe Bean an enormous debt. But for the general reader one of his most accessible books is Gallipoli mission, which tells the story of the Australian Historical Mission's return to the peninsula in early 1919. Bean and other members of the mission returned to Gallipoli to answer some of the many questions that remained about the campaign and to collect relics for the war memorial that Bean hoped to establish on his return to Australia. Regarded by some as Bean's finest book, it is an easy and extremely informative read. Although its focus is the mission's visit to Gallipoli in 1919, Gallipoli mission tells us much about the campaign; members of the mission retraced the steps of the first men to land on April 25 1915 and visited the sites of all of the major battles fought at ANZAC Cove. With the assistance of a Turkish officer, Zeki Bey, who had also fought in the campaign, the historical mission answered some of the riddles that had puzzled participants in the fighting. Zeki Bey's contribution adds much to Bean's narrative, as he was able to describe many incidents of interest to Bean from the Turkish point of view.
