During the forty-five months of World War II, the United States lost just under 1 percent of its adult male population; during the Civil War the casualty rate was somewhere between 4 and 5 percent; during the fourteen months of King Philip's War, Plymouth Colony lost close to 8 percent of its men. But the English losses appear almost inconsequential when compared to those of the Indians. Of a total Native population of approximately 20,000, at least 2,000 had been killed in battle or died of their injuries; 3,000 had died of sickness and starvation, 1,000 had been shipped out of the country as slaves, while an estimated 2,000 eventually fled to either the Iroquois to the west or the Abenakis to the north. Overall, the Native American population of southern New England had sustained a loss of somewhere between 60 and 80 percent.
