Daniel Joseph Burns Following the Revolutionary War, in 1779, General George Washington commissioned General John Sullivan and James Clinton to destroy the Cayugas and other members of the Haudenosaunee. These two Generals led 6,200 troops into many villages and crop fields of the Cayugas and the Haudenosaunee and destroyed them.
Lewis Ward Not following, in the middle of the Revolutionary War after devastating raids by some Haudenosaunee nations and the Tories in the Mohawk Valley. More (people) were massacred there than the Sullivan Campaign. (Scorched earth) warfare was not invented by Washington.
PLUS I think the crusades lead by the Catholic Church and the Spanish Conquest of Latin and Central America were much a few years earlier.
