i would think that they would have been used.
could you imagine the pshycological effect on your enemy,just think
there they are hunkered down in the cabin ir their soddie home,guns sticking out the windows ready to shoot at anything and everything that moves,
the people inside thinking tha they were safe, then all of a sudden in the midle of the night hey hear that sond of an arrow being released pffffffffft
they look and they see this little red flame getting closer and bigger and then it strikes the roof or wall of the their home,then they smell smoke.
then they see flames,then there re more arrows being shot at them,all on fire.
i think tha t would be enough for most people to run outside with gun in their hands and take thier chances wth theso called "savages" whoe were just trying to
protect their land and food stroes.
ya i think they were used, the natives may have been primitive by the whitemans standards back then,however they were far from being stupid, they used
any means they found to be usefull to survive
