The Cemetery was started in 1915 and used until April.1918 when it fell into German hands. After its recapture only a few more burials were added in September and October. This would be about the time that the last big German Offensive, which almost succeeded, ran out of steam and was being pushed back quickly by the Allies. I think it safe to say Private Wilkes would have been killed or died of wounds somewhere in the vicinity of where he now lies.
I have not discovered exactly what the 10th Battalion were up to but I would think everyone was taking advantage of the chance to take ground from the Germans as seen by the retaking of the Cemetery grounds.
Sorry its not much but I enjoy digging around and sometimes come up with a nugget.
