The Battle of the Avre (4–5 April 1918), part of the First Battle of Villers-Bretonneux, constituted the final German attack towards Amiens in World War I. It was the point at which the Germans got the closest to Amiens. It was fought between attacking German troops and defending Australian and British troops. The attack was an attempt to take Amiens, where other aspects of Operation Michael had failed. The Avre marked the beginning of the end for Ludendorf's German spring offensive.
