SWA - Looking for Individual Accounts / Cavalry Images

[Heliographen-Abteilung]

Greetings

I am working on a written documentary of the Northern campaign in GSWA 1914-1915 - basically Botha's advance from Walfisch Bay to Karib and the battles fought in the Swakop River Valley.

Any information on where I might find individual soldier's accounts or locations of images pertaining to the battle (especially from the Union side) would be greatly appreciated.
