The Indian approach to warfare was quite different to that of the US Cav.
War was for advancement, be that honour, prestige or possessions.
There was not a command system as the Cav. would have recognised.
If YOU felt you had got enough, honour, prestige or possessions, out of the
battle, then you would leave. e.g. I have killed 3 of the enemy & now have
a fine new horse, rifle & hat. Well it has been a good day. I will leave the rest
for the others.
