I can give you a brief overview of what the 15th Hussars got up to in Afghanistan, Cary:
They marched on Kandahar in December 1878/January 1879, with two squadrons of the 15th seeing action en route at Takht-i-Pul and in the Ghlo Pass; they were at Kandahar for just a few days before they accompanied General Biddulph up to Khelat-i-Ghilzai, stayed there a fortnight, and then returned to Kandahar. Soon after they were sent back into the Pishin Valley, opening up a route through Yargistan and then returning to India (Mirat). They started for the Afghan border again in August 1880, pausing at Quetta and eventually reaching Kandahar after the campaign had been effectively ended by Roberts' victory at the city earlier on Sept 1st. They were back in India in October.
Out of interest, the 15th Hussars suffered greatly from the cold at the Bolan Pass on their first advance to Kandahar, and greatly from the heat at the same location on their second advance in August 1880.
The remark 'Depot' on the medal roll means that Tomlinson was, at the time of the regimental roll's compilation (August 1881), serving with one of the depot companies of the 15th Hussars rather than with one of the 'service' troops.
If you're able and willing to
send some biographical info (and a copy of the photo for a mini portrait?) for the database that would be wonderful. I'm sorry I'm being a bit slow with email at the moment (just become a new dad :-)), but I am getting ready to compile some new entries soon (huge thanks to others who have recently sent info too, much appreciated - I will answer all emails eventually!).
All best - Garen
