NOWAG) will give it a try on January 18th, 2015. If you would like to do the same, a .pdf can be downloaded here. Please let us know how it goes.
The scenario is designed for use with Roy and Eric Alvarado's The Herero War Rules and Scenarios book based on The Sword and the Flame (TSATF) system. You can get a copy of Roy and Eric's Book in the US from Recreational Conflict and On Military Matters and in the UK from Caliver Books.
If you do decide you'd like to ride out into the bush with Oberlt. Volkmann, or lead Mbatona's Herero war band against him, you will need figures representing mounted troops (with foot dismounts and horse holders) for Volkmann's small force of 20 Schutztruppen and war volunteers (including boers), and also for 16 of the 64 Herero and two of their commanders. If you would prefer to read the extensive documentation for the historic battle that informs this scenario, there is a twelve part series archived with the label Uitkomst that should keep you busy for a while.
