There are no reliable estimates of the size of the attacking force. Isaac Stevens (who was not present), wrote to Washington that settlers estimated that 200 to 500 Indians had taken the field against them. Phelps put the number of enemy at 2,000, but (write Crowley and Wilma) "frontier military officers often inflated the number of opposing forces to reinforce their accomplishments (or to minimize their failures)." Community college historian Murray Morgan writes that early "reports seem to have multiplied by ten the actual numbers. There could not have been more than one hundred and fifty."
