Hello Granpa GHB - many thanks for your post.
I can help you out with those place names. In order: Ali Musjid, Peiwar Kotal, Charasia, Kabul and Sherpore, Ahmed Khel, and - as you have - Kandahar.
That's quite a list of actions! In fact, it's every clasp available. Looking at the medal roll I am not sure he was awarded all those clasps ... it does look like a tick in each column, but elsewhere, for others, 'yes' is written, and I think the 'yes' indicates an awarded clasp and the tick may actually be a badly styled dash (ie. no clasp).
I don't think anyone received both the Ahmed Khel clasp and the Kabul clasp - it's not impossible, but very unlikely.
It looks like Lt. G H Bittleston was attached to an un-recorded battery for the Afghan campaign - possibly the 4th Brigade, which could be one of five batteries (A, C, D, E or G). In Feb 1881 he moved from the 4th Brigade to serve as Aide-de-Camp to Brigadier-General Cobbe at Allahabad. Two months later he was A-d-C to Major-General Macpherson.
I will see if I can find out some more.
Thanks again - Garen.
