Technology is ever-advancing. These days you can keep a whole library's worth of books right in your pocket. Digital books are easier to carry, and can be easier to sift through to find exactly what you need. Warlord Games is adding to your available digital library now with two supplements for Black Powder, Zulu and Blood on the Nile, available in .pdf format.
As one would expect, Zulu covers the Anglo-Zulu War of 1879. Within the 92 pages, you'll see the history of and rules for forces for troops that fought in such battles as Islandlwana, Rorke's Drift, and Ulundi. Meanwhile, Blood on the Nile does much the same. However, this time we're in Sudan in North Africa and it's Mahdi and his troops that's fighting against the British. Again, you'll get a detailed history, as well as stats for the various troops that fought in that conflict.
