To Melani and SRS, I would say that I have never claimed that information sourced from Wikipedia is infallable, in this particular case the passage quoted happened to be in general agreement with what was written elsewhere and the Wikipedia section was more concise.

Estimates of numbers put between 2,000 and 20,000. The former would be too low and the latter way too high. One good way of estimating it is to look at how they would be fed, remembering that the tribes involved were Plains Indians, nomadic hunter gatherers. Think of the effort required under that culture to feed 20,000 people - basically they would be so busy surviving there would be nobody available for fighting. During the early 1800's in Europe the maximum time you could keep an army (50 to 80 thousand men) assembled was about three days, after which time it had to disperse. That was in country fairly intensively given over to agriculture with reasonable roads and means of transport.

Melani, you were prompted to edit an entry in Wikipedia because the information given was incorrect. With regard to what Little Hawk has stated in this thread, I have done nothing more. The fact that he is not too keen on that is of no concern, or significance to me whatsoever.
