Well look no further:
Anonymous, Record Book of the Scinde Irregular Horse Regiment, Volume 1, 1839-1851, Nissen & Parker, London, 1853
(Record Book of the Scinde Horse)
Just enter the phrase directly above at Google Books and Google Play and VOILA, you have tonnes of material to create everything from squadron versus horde to major battles and everything in between.
Note: This book should also be available on Archive.org/Texts.
Download both of the Volume One efforts for two reasons:
The Google Books version, or the one that pops up first, is an earlier edition, or possibly printed in/for India. Includes lots of typed inserts and raw data, along with battlefield maps.
The Google PLAY version is a much more polished effort, especially for Iphone/Ipad/Tablet owners. Among its many advantages are a lot of professionally drawn sketches of the terrain over which the smaller engagements were fought by the Scinde horse, giving you a good idea of just what you need to represent on your tabletop.
You may have to sift to find the two different versions, but it's worth it.
Besides regimental reports, there are a whole slew of Official Despatches ranging from the 1st Afghan War to the 2nd Sikh War and everything in between.
The 2nd Volume is primarily administrative during the lull between the 2nd SW and Sepoy Revolt, but it's also available for download.
It should keep you busy over the Memorial Day weekend.
This book is an absolute goldmine and should provide almost infinite gaming possibilities!
