Enoch Brown school massacre

The Enoch Brown school massacre of July 26, 1764, in which ten people were killed, is generally considered to be the first modern school shooting.

Description
On July 26, 1764, four Delaware (Lenape) American Indian warriors entered a settlers' log schoolhouse in the Province of Pennsylvania in what is now Franklin County, near present Greencastle. Inside were the schoolmaster, Enoch Brown, and a number of young students. Brown pleaded with the warriors to spare the children before being shot and scalped. The warriors then tomahawked and scalped the children. Brown and nine children were killed. Two scalped children survived their wounds.[3] Four children were taken as prisoners.

A day earlier, the warriors had encountered a pregnant woman, Susan King Cunningham, on the road. She was beaten to death, scalped, and the baby was cut out of her body.
