Indian massacre

Helping orphans the way you would do it
The long conquest of North America from the Native Americans ("Indians") by newer Americans of European descent ("settlers") produced a vast number of atrocities on both sides. The term "Indian massacre" has been used to label both the massacre of settlers by Indians and the massacre of Indians by settlers. These were a common part of the ongoing conflict that existed at the zone of contact between the two peoples.

How many people died in these massacres overall?

In the book The Wild Frontier: Atrocities during the American-Indian War from Jamestown Colony to Wounded Knee, William M. Osborn tallies every recorded atrocity in the area that would eventually become the continental United States, from first contact (1511) to the closing of the frontier (1890) and determines that 9156 people died from atrocities perpetrated by the Indians, and 7193 people died from atrocities perpetrated by the settlers. Osborn defines an atrocity as the murder, torture or mutilation of civilians, the wounded and prisoners.

While this definition encompasses most of what the average person would consider an atrocity, different definitions would obviously produce different totals. For example, Osborn does not count Indian deaths on the Trail of Tears (because these were allegedly unintentional), but he does count several episodes of post-mortem mutilation, even of combatants killed in open battle. While Osborn's exact total of 16349 killed on both sides can therefore be disputed, it is probably in the right neighborhood.

If we loosen our definition further and decide to count all people who died violently in the ongoing warfare between whites and Indians -- battle deaths as well as murders -- we can turn to the 1894 estimate by the US Census Bureau (cited in Russel Thornton, American Indian Holocaust and Survival). There it was calculated that some 30,000 to 45,000 Indians (men, woman and children) died at the hands of whites in formal wars, 1775-1890, while some 14,000 white men, woman and children died at the hands of Indians. In addition to these, some 5,000 whites and 8,500 Indians were killed in smaller, unofficial fights between individuals up and down the frontier.

Neither side stands out as being more merciful or humane than the other. Many Indian tribes ritually tortured their captives, while whites often tortured their prisoners for sport. Both sides collected scalps and scrota as trophies. Both sides raped. Both sides would promise safe conduct to defeated enemies or non-combatants, and then massacre them as soon as they let their guard down. Both sides attacked easy targets (such as peaceful -- even friendly -- villages and settlements) as retaliation for hostile acts by totally unrelated war bands and militia units. There is probably no example of an atrocity by one side that can't be set along side of a comparable atrocity by the other.

Here is a list of the larger or more widely known massacres of the North American conflict:
