Many thanks for this. I have confirmed him as present and entitled to the medals with both clasps. It looks as though he is also entitled to an Indian Mutiny, no clasps,
Agness enlisted into the 15th Hussars on 30 January 1846 at Westminster, London. In early April 1846 he transferred to the 3rd Light Dragoons staying with that regiment till 31 January 1856 when he moved to the 6th Dragoon Guards.
The timing of his initial enlistment means that he could not have served in the Sutlej Campaign. His army pension papers are available. He is indexed as William Agness 15th Hussars despite the papers clearly showing that he retired while serving in the 6th Dragoon Guards.
Needless to say, I am delighted.
I will add the books to my growing collection. I have just finished Churchill's Malakand Field Force boot and am now on to Con Coughlin's new book on Churchill and David Loyn's Butcher and Bolt. The whole North West Frontier history is fascinating.
