Another Ypres visitor here. We visited Tyne Cot, where I knew my great uncle was buried (I have the govt letter to my great aunt telling her about giving them all proper graves and where his was. Dated 1929?), little graveyards with perhaps a dozen headstones and Langemark, the German cemetery. We visited a few war cemeteries every day we were there. I always got the book of names, addresses and next of kin out, and looked for a couple of soldiers from areas I knew, found their graves and left a stone.
Obviously any graveyard is a sad place, but the important thing was that those lads weren't forgotten.
I like the peace of a cemetery, and if I walk through one now, will always keep an eye open for a war grave. The CWGC do a great job keeping the graves looking loved.
