Random attacks by Indian tribes. The frontier had swamps-to-mountainness terrain. Seeds didn't work in all parts of America, some lived healthy in one area while the same seed could die somewhere else there.

D. Most sides were using older rifles, including the French, which were from the 1880s-early 1900s.
