Info re 4th Btn Royal Welch Sept 1944

[Juliestagstag]

I found this site when researching for info about my husband's great uncle who died and is buried in Valkenswaard NL on 27th Sept 1944. He was a 19 yr old Private in the 4th Btn Royal Welch. We visited the grave on the 70th anniversary of his death. We have recently received his war records but not a lot of info on there. Does anyone know if we can find out which company he was in in his battalion?? I have access to the battalion diary.

Thanks in advance
