Last week my sister visited what is now known to be the grave of my grandfather who was killed at Neuve Chapelle. Athough I have visited it several times over the years it has always been listed as "believed to be" his grave. I have no idea what has changed but they are now certain his remains are there.

For many people, and I include myself, it needs a visit to somewhere like Tyne Cot to begin to grasp the scale of the killings on both sides.
