In October 43' there were still 98 American POW's on Wake Island when the US Navy conducted an airstrike.
In retribution, they were blindfolded and taken to the north side of the island and machine gunned.
One escaped long enough to carve the Wake Island Rock to let people know what happened but was soon captured and beheaded.
....and those werent just soldiers, sailors, and marines. Most were civilian contractors working on docks, generators, new radar, and seaplane facilities.
