This year is the centenary of the Aisne Battle on 27 May- the greatest one day advance on the Western Front since trench warfare began in September 1914.
This was a significant battle that also marked the turning point on the Western Front according to Sidney Rogerson it was 'The Last of the Ebb'. After this action in May-June 1918 it was the Allies that took to the offensive until the Armistice in 1918.
