BAGHDAD — Lieutenant General Mahdi Gharawi knew an attack was coming. In late May, Iraqi security forces arrested seven members of militant group Islamic State in Mosul and learned the group planned an offensive on the city in early June. Gharawi, the operational commander of Nineveh province, of which Mosul is the capital, asked Prime Minister Nouri Al-Maliki’s most trusted commanders for reinforcements.



With Iraq’s military overstretched, the senior officers scoffed at the request. Diplomats in Baghdad also passed along intelligence of an attack, only to be told that Iraqi Special Forces were in Mosul and could handle any scenario.



On June 4, federal police in Mosul under Gharawi’s command cornered Islamic State’s military leader in Iraq, who blew himself up rather than surrendering. Gharawi hoped the death might avert an attack. He was wrong. At 2:30 a.m. on June 6, Gharawi and his men returned to their operations room after an inspection of checkpoints in the city of two million. At that moment, convoys of pickup trucks were advancing from the west, driving across the desert that straddles Iraq’s border with Syria. Each vehicle held up to four IS fighters. The convoys shot their way through the two-man checkpoints into the city.



By 3:30 a.m., the militants were fighting inside Mosul. Within three days the Iraqi army would abandon the country’s second-biggest city to its attackers. The loss triggered a series of events that continues to reshape Iraq months later.



It unleashed a two-day charge by IS to within 95 miles (153 km) of Baghdad that caused the collapse of four Iraqi divisions and the capture or deaths of thousands of soldiers. It helped drive Maliki from office. And it pushed Western powers and Gulf Arab nations into launching air strikes on the militants in both Iraq and Syria.



But how Mosul was lost, and who gave the order to abandon the fight, have, until now, been unclear. There has been no official version: only soldiers’ stories of mass desertions and claims by infantry troops that they followed orders to flee.



Nevertheless, Baghdad has pinned the blame on Gharawi. In late August, he was charged by the Defense Ministry with dereliction of duty. He is now awaiting the findings of an investigative panel and then a military trial. If found guilty, he could be sentenced to death. (Four federal police officers who served under Gharawi are also in custody awaiting trial, and could not be reached.) Parliament also plans to hold hearings into the loss of Mosul.



An investigation by Reuters shows that higher-level military officials and Maliki himself share at least some of the blame. Several of Iraq’s senior-most commanders and officials have detailed for the first time how troop shortages and infighting among top officers and Iraqi political leaders played into Islamic State’s hands and fuelled panic that led to the city’s abandonment. Maliki and his defense minister made an early critical mistake, they say, by turning down repeated offers of help from the Kurdish fighting force known as the peshmerga.



Gharawi’s role in the debacle is a matter of debate. A member of the country’s dominant Shi’ite sect, he alienated Mosul’s Sunni majority before the battle, according to the provincial governor and many citizens. That helped give rise to IS sleeper cells inside Mosul. One Iraqi officer under his command faulted Gharawi for not rallying the troops for a final stand. For his part, Gharawi says he stood firm, and did not give the final order to abandon the city. Others involved in the battle endorse that claim and say Gharawi fought until the city was overrun. It was only then that he fled.



Gharawi says three people could have given the final order: Aboud Qanbar, at the time the defence ministry’s deputy chief of staff; Ali Ghaidan, then commander of the ground forces; or Maliki himself, who personally directed his most senior officers from Baghdad. The secret of who decided to abandon Mosul, Gharawi says, lies with these three men. Gharawi says a decision by Ghaidan and Qanbar to leave Mosul’s western bank sparked mass desertions as soldiers assumed their commanders had fled. A senior Iraqi military official backs that assertion. None of the three men have commented publicly on their decisions in Mosul. Maliki has declined Reuters requests for an interview for this article. Qanbar has not responded, while Ghaidan could not be reached.



Lieutenant General Qassim Atta, a military spokesman with close ties to Maliki, told Reuters last week that Gharawi “above all others ... failed in his role as commander.” The rest, he said, “will be revealed before the judiciary.”



In many ways, Gharawi’s story is a window into Iraq. The Shiite general has been a key figure since 2003, when the Shiites began gaining power after the United States toppled Saddam Hussein. Shiite leaders once saluted Gharawi as a hero, while Sunnis see him as a murderer who used Iraq’s war on extremism as a cover for extorting money from businesses and menacing innocent people with arrests and killings.



As IS militants raced toward Mosul before dawn on June 6, they hoped only to take a neighborhood for several hours, one of them later told a friend in Baghdad. They did not expect state control to crumble. They hurtled into five districts in their hundreds, and would, over the next few days, reach over 2,000 fighters.



As the militants infiltrated the city, they seized military vehicles and weapons. The sergeant based there said they also hanged soldiers and lit them ablaze, crucified them, and torched them on the hoods of Humvees.



On the morning of June 8, Gharawi met Nineveh governor Atheel Nujaifi. The governor was no friend — he had previously accused Gharawi of corruption, an allegation the general rejected. Now the city’s fate hinged on Gharawi. One of Nujaifi’s advisers asked the general why he had not counter-attacked.



“There are not enough forces,” Gharawi told them. General Babakir Zebari was Gharawi’s superior and chief of staff for Iraq’s armed forces back in Baghdad. He agrees there were not enough men to defeat the jihadists. And Maliki had already rejected a chance to change that.



On June 7, Kurdistan President Massoud Barzani had offered to send Kurdish peshmerga fighters to help. The offer went all the way up to Maliki, who rejected it twice through his defence minister, according to Zebari.



On the afternoon of June 8, the Islamic State surged. More than 100 vehicles, carrying at least 400 men, had crossed to Mosul from Syria since the start of the battle. Sleeper cells hiding in the city had been activated and neighbourhoods rallied to them, according to police and military.



Within hours, though, Gharawi’s command was thrown into disarray. Multiple military sources say Ghaidan and Qanbar sacked a divisional commander after he refused to send men to defend the Mosul Hotel. The sacked general, who reported to Gharawi, theoretically commanded 6,000 men, though many were AWOL.



General Zebari calls the order another huge mistake: “In crisis, you can’t replace the commander.” — Reuters
