The Third Battle of Antwerp, 1-10 October 1914, was the final phase of a more prolonged period of fighting around Antwerp that had begun during the third week of August 1914 when the bulk of the Belgian army had fallen back from its initial front line to a new line based around Antwerp. It ended with the surrender of the city on 10 October.
The Battle of Cambrai, 20 November-7 December 1917, was the first large scale tank battle in history.

It began as a German offensive (the Champagne-Marne Offensive, 15-18 July) but ended with a successful Allied counter-attack (the Aisne-Marne Offensive, 18 July-5 August) which saw the German army pushed back almost to the line it had occupied before their great success during the Third Battle of the Aisne
The Champagne-Marne Offensive, 15-18 July 1918, was the last of Ludendorff’s five offensives of 1918 that had come close to breaking the Allied lines
The Aisne-Marne Offensive, 18 July-6 August 1918, was the second phase of the Second Battle of the Marne (15 July-6 August) and marked a major turning point in the fighting on the Western Front in 1918.
