8th Division was next in action at Villers-Bretonneux on 24–25 April, when 490th (HC) Fd Co was in action, losing numerous casualties to Mustard Gas. The division was then moved south, where it faced another heavy German attack and consequent retreat at the Aisne (27 May – 6 June). The exhausted division was then withdrawn into reserve, with the sappers at St Quentin and Le Treport.
