Thank you very much for this, Ady and rac1473. William Henry's personal records seem to be missing ('burnt' I guess), so it is really useful to have these bits of information. He also got Military Medal, and I have a copy of that card and the War Diary where it was reported. I am wondering if he got the medal at the same time he was wounded, and I will look into that via some war diary copies I have.
I am wondering if you would be so kind as to have a look at his brother's medal card - Joseph James - this will be the last one, I promise. You may notice they both went to France on the same day. Again, it is the 'remarks' that I don't understand. Also' W.O.Bl.II' - ? Joseph also was mentioned in despatches at the same time as William, and he also got Silver War Badge, so I am thinking he too must have been wounded.
Both men survived and had lives after the war, I am pleased to report.
Many thanks for all your help.
