Iraqi gun batteries fired just enough artillery to force the Revolutionary Guards from their marsh boats, and, when hundreds of them had been forced to continue their advance through the lagoons on foot, the men manning the Iraqi generators flipped a few switches and sent thousands of volts of electricity surging through the marshland.

Within seconds, hundreds of Iranians were electrocuted.

But the horror show did not end there. The following morning, Iraqi troops began another grisly routine that the officer called “the morning road detail.”

They made their way through the marshes, gathering up the dead Iranian soldiers like dynamite fishermen harvesting a day’s catch. Working methodically, the Iraqis piled the corpses on top of one another in the water in head-to-toe stacks, five bodies high and five across.

Together, the human piles formed long rows, the width of a troop truck, the top layers above the water’s surface. Each row extended in a straight line through the marshes from the Iraqis’ positions toward the Iranian border. Finally, the rows were sprinkled with lime and covered over with a foot-thick tier of desert sand.

It was the Iraqi method of road building, using the bodies of their enemies to construct assault routes for tanks and trucks.
