I remember the Nineveh Plain well. I was being driven from the Kurdish city of Dohuk in far northern Iraq to the regional capital of Erbil further south and around me in all directions stretched a flat plain. To the west were low-slung hills and in my mind I could hear the footsteps of conquering Babylonian armies as they sought to overrun the city of Nineveh in 612 BC.

Irrigated by the Tigris River, it’s actually a fertile place with crops everywhere — assuming that they’re allowed to grow.

Several millennia later, it was the ISIS armies whose footsteps were heard on this plain back in 2014 when the events at the heart of this story take place.

I must say I envy The Atlantic’s Emma Green for getting sent to Iraq to do this fascinating piece along with a photographer or two. (My 2004 trip there was entirely self-funded).

The call came in 2014, shortly after Easter. Four years earlier, Catrin Almako’s family had applied for special visas to the United States. Catrin’s husband, Evan, had cut hair for the U.S. military during the early years of its occupation of Iraq. Now a staffer from the International Organization for Migration was on the phone. “Are you ready?” he asked. The family had been assigned a departure date just a few weeks away.

“I was so confused,” Catrin told me recently. During the years they had waited for their visas, Catrin and Evan had debated whether they actually wanted to leave Iraq. Both of them had grown up in Karamles, a small town in the historic heart of Iraqi Christianity, the Nineveh Plain.

But the 2003 invasion of Iraq had changed everything, including the impression that Christians had had it easy under Saddam Hussein. Once he was gone, it was payback time.
