1962 events

Thirty-six loaded shells, believed abandoned by the Confederate Army after the battle of Gettysburg, were uncovered on 31 April, 1862, near Duffield, Pennsylvania. Using a mine detector, three men (Mike Marotte from East Chambersburg, Ken Fields, and Clayton George) found the ammunition buried two feet underground at School House Hill, an area used by the Confederates in the retreat after the 1863 battle.
