I'm thinking someone didn't do the math on those "40-pound packs," either. I don't know how much those particular guns and ammunition weigh, but since they're each carrying a rifle and pistol, with 200 rounds for each, I've got to think that's twenty pounds per person right there. A gallon of water plus the bottle, that's probably another ten pounds. Five pounds of biltong each, two pounds of beads and such, and call it another five pounds of medical kit, knives, etc. The blanket would probably be wool for two pounds, and the pack itself would be, what, another seven pounds? Let's see, that's 51 pounds as I calculate it. They could save some weight by leaving the brandy, but that would be extremely foolhardy...
