The wars in Iraq and Afghanistan were brutal, but when ISIS emerged from the chaos, things became much darker. They were not a normal enemy. They hunted, kidnapped, tortured, and executed in ways that shocked the entire world.
The nightmare began in 2003 when the United States invaded Iraq. The primary goal was to topple Saddam Hussein and end his regime. But once Saddam was gone, the country quickly spiraled into chaos.
Various armed groups began fighting not just American forces, but each other as well. This was the beginning of a long and bloody insurgency.
One of the most dangerous groups at that time was al-Qaeda in Iraq, led by a man named Abu Musab al-Zarqawi. He was notorious for his extreme violence. He did not just fight soldiers; he wanted to shock the world.
He was the first to record beheadings of captives on camera, an act that terrified millions as videos spread across the internet. His goal was to intimidate the United States and anyone who opposed him, while simultaneously attracting new fighters who admired his brutality. In 2006, al-Zarqawi was killed in an American airstrike.
Many believed his death would weaken the insurgency forever. But instead, his followers adapted. They changed their names, rebuilt their networks, and waited for the right moment to rise again.
The war in Iraq dragged on, and violence grew worse. By 2011, when American combat troops left Iraq, the country was deeply unstable. Corruption was rampant, the Iraqi army was weak, and sectarian divisions between Sunnis and Shias had created deep anger.
al-Zarqawi’s old group exploited this unrest to rebuild itself. By 2013, they had transformed into something far larger: ISIS, or the Islamic State in Iraq and Syria. Unlike other terrorist groups, ISIS wanted to do more than just carry out bombings.
They wanted to seize territory and rule it. They took over towns, set up their own checkpoints, and even established their own courts and police forces. They called their land a caliphate, claiming it was a religious state for all Muslims.
Thousands of foreign fighters flocked from around the world to join them, making the group more dangerous than anyone had anticipated
When American soldiers returned to the region to help fight ISIS, they quickly realized this enemy was different. ISIS did not view American forces merely as battlefield adversaries. They saw them as powerful symbols.
Capturing or killing an American soldier was not just a military victory; it was an opportunity to send a message to the entire world. For ISIS, every act of violence had to be filmed, published, and used as propaganda. They wanted to show that even the world’s most powerful army could be humiliated.
But even before ISIS existed under that name, the fighters who would later form the group were already displaying the kind of cruelty that would make them infamous
One of the most shocking moments occurred in Fallujah in 2004. Four American contractors working for Blackwater security firm were driving through the city when they were ambushed. Their convoy was attacked with rifles and grenades.
After they were killed, the gunmen did not stop. They burned the bodies and dragged them through the streets. Eventually, they hung the remains from a bridge over the Euphrates River.
For American soldiers watching the news and for families back home, those images were horrifying. Many US troops said this was the moment they realized what kind of enemy they were facing. This was not a group that followed conventional rules of war.
They wanted to shock, humiliate, and terrify. And they succeeded
After that, ambushes became more frequent. Insurgents studied American patrols and waited for the right moment to strike. They often attacked convoys in narrow streets or crowded markets, places where it was nearly impossible for soldiers to respond without risking civilian lives.
The most feared weapon became the improvised explosive device, known as the IED. These roadside bombs were cheap to make but deadly. A simple artillery shell buried in the dirt could destroy a heavily armored Humvee.
By 2006, IEDs had become the number one killer of American troops in Iraq. But the insurgents wanted more than just explosions. They wanted prisoners.
For them, capturing an American alive was more valuable than killing one. A captured soldier could be tortured for information. More importantly, they could be used for propaganda.
Insurgents realized that a single hostage video could spread fear across the world. It gave them attention, power, and leverage over governments
This created a terrifying reality for American soldiers. Many began whispering to each other that if they were ever cornered, it was better to fight to the last bullet rather than be taken alive. But in October 2006, that fear became reality.
An American soldier was captured alive. His name was Corporal Ahmed Qusai al-Taayie. His story was different from most.
He was born in Iraq but grew up in Ann Arbor, Michigan, after moving to the United States with his family. Wanting to serve his new country, he joined the US Army. Because he spoke both Arabic and English, he was especially valuable as a translator.
Many units relied on him to communicate with locals and gather intelligence. But his background also made things complicated. Unlike most American soldiers, he had family ties in Iraq.
While stationed in Baghdad, he married an Iraqi woman. On the day he disappeared, he was not on a combat mission. He was visiting his wife’s relatives when gunmen kidnapped him.
Witnesses later said a group of about twelve gunmen, linked to Shia militias cooperating with groups tied to al-Qaeda in Iraq, stormed the area and took him away
Search efforts began immediately. American troops raided neighborhoods, set up checkpoints, and even offered rewards for information. But Baghdad in 2006 was chaos, filled with sectarian violence, militias, and constant bombings.
Finding one man was like searching for a needle in a haystack. For years, no one knew exactly what happened to Ahmed. Many rumors circulated.
Some claimed he was being held prisoner in safe houses. Others said he was executed shortly after his capture. Gunmen issued threats from time to time, but they never provided clear proof he was alive.
His case haunted his family in Michigan and his fellow soldiers in Iraq. Finally, in 2012, six years after his kidnapping, his remains were found. The truth was confirmed: he had been executed.
The long wait ended in a heartbreaking conclusion. For many in the US military, this case carried a particularly harsh message. Ahmed was not just an American soldier; he was also Iraqi-born.
If anyone deserved mercy, it was him. But the gunmen showed no mercy. For them, wearing the American military uniform mattered more than blood or origins
By the summer of 2014, the war in Iraq took a shocking turn. ISIS stormed into Mosul, Iraq’s second-largest city, and the Iraqi army collapsed within days. Entire divisions of soldiers abandoned their posts, leaving behind weapons, vehicles, and even American-made tanks.
This gave ISIS not just territory, but also vast amounts of weapons, ammunition, and money. They raided banks, seizing hundreds of millions of dollars. With this wealth, they expanded rapidly.
Thousands of new recruits poured in, not just from Iraq and Syria, but from countries across the Middle East, Europe, Africa, and even the United States. Fighters came because ISIS claimed it had established a caliphate. In Mosul and other cities they seized, ISIS began building its own version of government.
They raised their black flag over government buildings, established their religious police, and imposed strict rules on people’s daily lives. They even printed their own currency, trying to show the world they were not just rebels, but rulers
But behind this image of power was a system built on terror. Anyone who resisted ISIS was beaten, tortured, or killed. They established prisons where people disappeared.
Some of these prisons were just basements or abandoned buildings. But inside were cages, chains, and torture devices. Prisoners suffered starvation, beatings, and were often executed.
Videos leaked showing men locked in iron cages, burned alive, or lined up and shot. For American soldiers returning to Iraq during that time, the threat felt more severe than ever. Soldiers knew what happened in those prisons, and they understood ISIS would not keep them alive for long.
Every mission carried the same unspoken rule: do not get captured. But the nightmare became reality again
In June 2009, US Army Sergeant Bowe Bergdahl, who was stationed at a small outpost in eastern Afghanistan, left his base under mysterious circumstances. Shortly afterward, he was captured by the Taliban, an armed group fighting against American and Afghan forces. His disappearance triggered one of the largest search operations of the entire war.
Soldiers risked their lives trying to find him. During those searches, many American troops were killed in firefights and roadside bomb attacks. For the Taliban, Bergdahl became a bargaining chip.
They released videos of him in captivity to prove he was alive, then used his life as leverage. After nearly five years, in 2014, Bergdahl was freed in a controversial prisoner swap, when the United States agreed to release five Taliban leaders from Guantanamo Bay. ISIS, which was rising in power during that period, studied what happened carefully.
They saw how a single captured soldier forced the US government to negotiate, and how that story dominated news for years. But unlike the Taliban, ISIS was not interested in prisoner exchanges. They were not interested in deals or negotiations.
They wanted something darker
But they did not succeed every time. One such case occurred on October 22, 2015, when a secret nighttime raid was launched in al-Huwayja, Iraq. The target was a prison where ISIS held dozens of men who were about to be executed.
The mission was carried out by Kurdish special forces known as the Peshmerga. But they were not alone. A small team of American Delta Force operators accompanied them, providing the kind of expertise and firepower the Kurds did not possess.
These men were among the most highly trained soldiers in the world, used only for the most dangerous missions. As the raid began, intense firefight erupted almost immediately. The prison was defended by ISIS fighters determined to fight and refusing to surrender.
The battle turned into close-quarters combat, room by room, hallway by hallway. Amid the chaos, Master Sergeant Joshua Wheeler, a combat veteran who had participated in numerous missions, saw that the Kurdish fighters were pinned down and in danger. Without hesitation, he rushed forward, leading the way through enemy fire to break the resistance.
His actions allowed the assault team to continue advancing and free more than 70 prisoners who were on the verge of being killed. Tragically, Wheeler was wounded and killed during the battle. He became the first American combat death in the war against ISIS.
His death carried heavy meaning. For American forces, it showed the level of danger involved in fighting ISIS directly, even in limited numbers. For the prisoners he helped rescue, his sacrifice meant life instead of certain death
On May 3, 2016, the war against ISIS claimed another American life. This time, the fallen was a Navy SEAL, Charles Keating IV, a young but highly skilled member of an elite unit. He was part of a small team supporting Kurdish Peshmerga fighters near the town of Tel Skuf in northern Iraq.
That morning, ISIS launched a massive attack with hundreds of fighters, armored vehicles, and heavy weapons. Their goal was to breach Kurdish lines and prove they could still strike hard even after months of defeats. Keating and his fellow special operators found themselves quickly in the storm.
They were vastly outnumbered and caught off guard. Mortar rounds rained down. Machine gun fire swept across open ground, and suicide truck bombs attempted to breach defenses.
Amid that chaos, Keating rushed forward to help secure defensive positions and protect the Kurds he was fighting alongside. During that fierce battle, he suffered fatal wounds. His comrades fought desperately to hold their positions, and airstrikes were eventually called in to repel ISIS.
But Keating’s fate could not be changed. Back in the United States, the news hit like a thunderbolt. He was only 31 years old, a graduate of Arizona State University, from a military family with a long history of service.
His loss was not just felt on the battlefield; it was deeply personal for many back home. ISIS quickly exploited his death for propaganda. They released videos boasting that one of America’s best soldiers had fallen at the hands of their fighters.
For them, every American loss was a way to claim victory and inspire new recruits. But for Americans, Keating’s sacrifice was a painful reminder that the fight against ISIS was far from over
One of the bloodiest moments occurred in 2017 in the dusty village of Tongo Tongo in Niger, Africa. Not all ISIS battles were in Iraq and Syria. The group had branches and allies in Africa as well.
There, a small team of American special forces, working with local Nigerian soldiers, was on what was supposed to be a routine patrol. They thought it would be low-risk, but they were moving through an area where ISIS fighters were growing stronger. That morning, the soldiers were suddenly ambushed.
About 50 ISIS fighters, armed with machine guns, vehicles, and rocket launchers, attacked them from multiple directions. The American and Nigerian soldiers were heavily outnumbered. Amid the chaos, four Americans were killed, including Sergeant Bryan Black, Sergeant Jeremiah Johnson, Sergeant Dustin Wright, and Staff Sergeant David Johnson.
Many Nigerian soldiers also lost their lives. The fighting lasted for hours. The soldiers fought bravely, calling for air support and trying to escape the kill zone.
The US Army later admitted that the team did not expect such a large enemy force, and poor planning had left them vulnerable. Families back home were shocked to learn their loved ones were operating in such dangerous conditions, in a country many Americans did not even know their troops were in. Adding to the tragedy was what happened after the battle.
ISIS fighters found the body of Staff Sergeant David Johnson, who had become separated from his team. They filmed his remains and posted the footage online as propaganda, boasting that they had killed an American soldier. The video spread quickly across jihadist networks before American officials could stop it.
For Johnson’s family, it was unbearable. One final cruelty added to their devastating loss
Back in Syria, the war was especially dangerous for civilians who came from other countries. Journalists like James Foley and Steven Sotloff went there to cover the conflict, hoping to show the world what was really happening. Instead, they were captured by ISIS.
Both men were brutally executed on camera. Those videos were released online for the entire world to see. For American soldiers, those executions felt deeply personal.
Although Foley and Sotloff were not military, their deaths showed how far ISIS was willing to go. Soldiers immediately understood that if ISIS could treat innocent journalists that way, captured troops would likely face something even worse. Behind the scenes, the US government was working desperately to find where hostages were being held.
Intelligence agencies tracked phone calls, satellite imagery, and informants on the ground to try to locate secret prisons. Special forces prepared and launched rescue raids whenever there was a slight chance of saving someone. But many of those missions ended too late.
By the time soldiers reached locations, hostages had already been killed or moved elsewhere
But by mid-2017, the tide had turned decisively against ISIS. American forces, working with the Iraqi army, Kurdish fighters, and Syrian allies, launched a series of ferocious offensives to eliminate ISIS strongholds one by one. The battles were long, bloody, and exhausting.
Mosul became the main target. In July 2017, after months of intense street fighting, Mosul finally fell. But the cost was staggering.
Soldiers described the battle as one of the toughest since World War II. Every building was a fortress. Every street was booby-trapped.
ISIS fighters used civilians as shields, planted bombs in doorways, and turned entire neighborhoods into minefields. Many American soldiers who worked alongside Iraqis witnessed atrocities they would never forget. Just three months later, in October 2017, Raqqa, the so-called capital of ISIS, collapsed after a massive assault led by Kurdish and Arab fighters backed by relentless American airpower.
The victory was celebrated around the world. But again, victory came with deep scars. The city was left in ruins, filled with mass graves and grieving families.
For American soldiers who fought in Mosul, Raqqa, and countless small towns, the victories did not feel clean. Many returned home carrying wounds that were not always visible. They had seen ISIS’s cruelty up close.
Some came back missing limbs. Others carried memories that haunted them in silence. The physical fighting was ending, but the trauma would never end
The Pentagon has never released full details about every American who fell into ISIS hands. Some cases remain classified, hidden from public view. Families whisper about loved ones lost under mysterious circumstances.
Rumors circulate among veterans about soldiers who were captured alive, tortured, and never seen again. By 2019, the last piece of ISIS territory fell in Baghuz, Syria. But even as the black flag fell, the memories remained.
