Russell Weigley wrote that analysis of the campaign before the Second World War led to "a belief among most of the armed forces of the world" that amphibious assaults could not succeed against modern defences and that despite landings in Italy, Tarawa and the Gilberts, arguably this perception continued until Normandy in June 1944. Hart wrote that despite the pessimistic analyses after 1918, the situation after 1940 meant that landings from the sea were unavoidable and it was only after Normandy that the belief that opposed landings were futile was overcome. The memory of Gallipoli weighed upon the Australians during the planning of the Huon Peninsula campaign in late 1943. In September, the Australians made their first opposed amphibious landing since Gallipoli at the Battle of Finschhafen in New Guinea. The landing was hampered by navigational errors and troops came ashore on the wrong beaches but they had been trained according to the lessons of Gallipoli and quickly reorganised to push inland.
