Trouble in the Umphosi Valley
Zulus
2 units of rifles (12 figures each), one on the Kopje, one in the village.
8 Impis (24 figures each). 2 behind the left hand hill, 6 behind the right hand hill.
For every 2 bases lost, you may bring on a fresh base behind the village (wise to bring them on only when you have a complete unit).
