The description of the engagement as a battle is disputed because of both the overwhelming firepower of the attackers and the lopsided casualties. The author Vic Hurley wrote, By no stretch of the imagination could Bud Dajo be termed a 'battle'. Mark Twain commented, In what way was it a battle? It has no resemblance to a battle ... We cleaned up our four days' work and made it complete by butchering these helpless people. A higher percentage of Moros were killed than in other incidents now considered massacres. For example, the highest estimate of Native Americans killed at the Wounded Knee Massacre is 300 out of 350 (a death rate of 85 percent), whereas in Bud Dajo there were only six Moro survivors out of a group estimated at 1,000 (a death rate of over 99 percent). As at Wounded Knee, the Moro group included women and children.
