The soldiers at the blast crater sensed something was wrong.
It was August 2008 near Taji, Iraq. They had just exploded a stack of old Iraqi artillery shells buried beside a murky lake. The blast, part of an effort to destroy munitions that could be used in makeshift bombs, uncovered more shells.
Two technicians assigned to dispose of munitions stepped into the hole. Lake water seeped in. One of them, Specialist Andrew T. Goldman, noticed a pungent odor, something, he said, he had never smelled before.
He lifted a shell. Oily paste oozed from a crack. “That doesn’t look like pond water,” said his team leader, Staff Sgt. Eric J. Duling.
The specialist swabbed the shell with chemical detection paper. It turned red — indicating sulfur mustard, the chemical warfare agent designed to burn a victim’s airway, skin and eyes.
All three men recall an awkward pause. Then Sergeant Duling gave an order: “Get the hell out.”
Five years after President George W. Bush sent troops into Iraq, these soldiers had entered an expansive but largely secret chapter of America’s long and bitter involvement in Iraq.
From 2004 to 2011, American and American-trained Iraqi troops repeatedly encountered, and on at least six occasions were wounded by, chemical weapons remaining from years earlier in Saddam Hussein’s rule.
In all, American troops secretly reported finding roughly 5,000 chemical warheads, shells or aviation bombs, according to interviews with dozens of participants, Iraqi and American officials, and heavily redacted intelligence documents obtained under the Freedom of Information Act.
The United States had gone to war declaring it must destroy an active weapons of mass destruction program. Instead, American troops gradually found and ultimately suffered from the remnants of long-abandoned programs, built in close collaboration with the West.
The New York Times found 17 American service members and seven Iraqi police officers who were exposed to nerve or mustard agents after 2003. American officials said that the actual tally of exposed troops was slightly higher, but that the government’s official count was classified.
The secrecy fit a pattern. Since the outset of the war, the scale of the United States’ encounters with chemical weapons in Iraq was neither publicly shared nor widely circulated within the military. These encounters carry worrisome implications now that the Islamic State, a Qaeda splinter group, controls much of the territory where the weapons were found.
The American government withheld word about its discoveries even from troops it sent into harm’s way and from military doctors. The government’s secrecy, victims and participants said, prevented troops in some of the war’s most dangerous jobs from receiving proper medical care and official recognition of their wounds.
“I felt more like a guinea pig than a wounded soldier,” said a former Army sergeant who suffered mustard burns in 2007 and was denied hospital treatment and medical evacuation to the United States despite requests from his commander.
Congress, too, was only partly informed, while troops and officers were instructed to be silent or give deceptive accounts of what they had found. “ ’Nothing of significance’ is what I was ordered to say,” said Jarrod Lampier, a recently retired Army major who was present for the largest chemical weapons discovery of the war: more than 2,400 nerve-agent rockets unearthed in 2006 at a former Republican Guard compound.
Jarrod L. Taylor, a former Army sergeant on hand for the destruction of mustard shells that burned two soldiers in his infantry company, joked of “wounds that never happened” from “that stuff that didn’t exist.” The public, he said, was misled for a decade. “I love it when I hear, ‘Oh there weren’t any chemical weapons in Iraq,’ ” he said. “There were plenty.”
