The Battle of the Menin Road Ridge, sometimes called "Battle of the Menin Road", was the third British general attack of the Third Battle of Ypres in the First World War. The battle took place 20–25 September 1917, in the Ypres Salient in Flanders on the Western Front. During the pause in Allied general attacks between late August and 20 September, the British changed some infantry tactics, by adopting the "leap-frog" method of advance, when waves of infantry stopped once they reached their objective, then consolidated the ground, while other waves passed through the objective to attack the next one and the earlier waves became the tactical reserve. General adoption of the method was made possible when more artillery was brought into the salient and by increasing the amount of air support of ground operations and specialising the tasks of air defence, contact-patrol, counter-attack patrol, artillery observation and ground-attack.
