Nobescourt Farm is smack in the centre of the area of the 21 March 1918 German offensive Operation Michael. Clearly the ground was also fought over in the last days of 1918 during the allied final advance but the former period may well be the fighting referred to.
In March it was the ground over which the German Second Army advanced. Facing there was the allied Fifth Army, so it is there to look for units that took part. Roisel was defended in March 1918 by units of the 66th East Lancashire Division and many men of that division who died in March 1918 are buried at Roisel so it is there to look for diaries.
Need more time.
