The Second Battle of Bapaume was a battle of World War I that took place at Bapaume, France between 21 August and 3 September 1918. It followed the Battle of Amiens and is also referred to as the second phase of that battle. The British and Commonwealth attack is often taken to be the turning point of the First World War on the Western Front and the beginning of what was later known as the Allies'Hundred Days Offensive. Improved armoured support and artillery bombardment weakened once impregnable positions and helped the Allied forces tear holes through trench lines. On 29 August New Zealanders, after heavy fighting, occupied Bapaume having broken through, with the British 5th Division, the very strong Le Transloy–Loupart trench system and having overcome many other strong points around the town.
