In 2006, Diyala province had special significance for the insurgents. When Abu Musab al-Zarqawi was head of al-Qaeda in Iraq, he designated Diyala has the capital of the Islamic caliphate he planned to establish in the country. He located his headquarters in a village north-west of Baqubah. In April 2006, on Saddam Hussein's birthday, insurgents launched a coordinated offensive throughout the province, attacking Muqdadiyah, Balad Ruz, Kanaan, Khalis, Khan Bani Sa'ad and the capital Baqubah. The insurgents used the rural areas east and southeast of the capital, from Balad Ruz to Turki as supply bases for their bombing campaigns in Baghdad and Diyala. They were also based in the Diyala river valley, northeast of Baqubah, where they fought for control of Muqdadiyah, an important line of communication to Lake Hamrin, Kirkuk and Iran. The insurgents also had control of the tribal areas of Khan Bani Sa'ad south of Baqubah to Salman Pak, south-east of Baghdad.
Shortly after the insurgent victory in Baghdad after Operation Together Forward insurgents began, little by little, moving their resources from Baghdad, now more than 80 percent under insurgent control, and Al Anbar province, which was also almost completely under insurgent control, to the province of Diyala northeast of Baghdad. The first signs of increased insurgent activity in Diyala came after U.S. forces found an insurgent bunker complex near the village of Turki and fought a bloody battle. Also a few weeks later fighting between police and insurgents after an attack on Baquba's police headquarters shuts down the city, closing the university, schools and most stores, and clearing the streets of everyone, except a few who scurry about to stock up on food. At least 55 militants are killed in clashes in the preceding days, according to anonymous police sources. During the fighting a mass grave with 28 bodies was discovered. After that U.S. and Iraqi forces begin raids in the city. The morgue in the city reports by the beginning of December 2006 that it had received 102 bodies in the previous two weeks. After the announcement of a new attempt by the U.S. and Iraqi security forces to take back the streets of Baghdad the insurgents started to speed up their move and it is believed that the reason behind the little resistance found by the security forces in Baghdad during Operation Law and Order is that most of the insurgents have moved to Diyala.
On Christmas Day it was reported that the capital of the province, Baquba, had fallen under insurgent control. An Iraqi news cameraman went to the city and reported seeing hundreds of gunmen with AK-47's in cars and pickups parading through the city. There was no sign of the security forces except for the bodies of a few executed by the insurgents. After that there were increased insurgent attacks on the U.S. and Iraqi forces around Baquba and in the rest of the province.
Mid-January U.S. and Iraqi forces conducted a series of raids that resulted in 93 insurgents killed and 57 captured. Despited this however the insurgents had some successes early in the campaign, mainly, when they shot down a Black Hawk helicopter on January 20 killing twelve U.S. soldiers. The helicopter was carrying mostly officers from the U.S. National Guard. The dead included a colonel who was the top American military doctor in Iraq.
In January 2007, it was reported that Sunni insurgents were able to kidnap the mayor of Baquba and blow up his office, despite promises from American and Iraqi military officials that the situation in the city was "reassuring and under control". The city at its peak had over 300,000 residents, but a February 2007 report labeled the city a "ghost town" as most residents had fled.
Iraqi security forces under attack
In two separate incidents in the beginning of March, insurgents captured 32 members of the Iraqi security forces. The bodies of 14 captured policemen were found shortly after, and the 18 other soldiers and policemen were shown on television with a message that they would be executed. Suicide bombers continued to attack in Diyala, targeting not only military but also civilian targets such as a cafe in Balad Ruz, where 30 people were killed on March 7. The capture of policemen continued, with another 10 policemen captured and 1 killed when insurgents overran a police station in the town of Hibhib. The bodies of five of the policemen were found the next month. Also, 20 Iraqi soldiers and policemen were captured at the beginning of April and were executed several days later.
On March 23, the provincial director of civil defense, Colonel Ahmed Kadhim Jawad, was killed in Khalis.
On March 13, 700 men from the Army's 5th Battalion, 20th Infantry Regiment, which includes Stryker armored vehicles, were sent from Baghdad to Diyala as reinforcements to the 3,500 U.S. and 20,000 Iraqi soldiers already in the province. The next day, as the first batch of the reinforcements was moving close to the outskirts of Baquba, the Stryker convoy was hit by machine-gun, RPG and mortar fire. In the ensuing chaos one American soldier was killed, 12 were wounded and two Stryker armored vehicles were destroyed. The same day, in two other separate incidents, two more American soldiers were killed in the province.
Attack on Qubah
On March 24, the U.S. military started operations to retake the Baqubah River valley. The operation started with an attack on the insurgent-held village of Qubah. Up to 13 Chinooks, Blackhawks and Apache gunships from FOB Warhorse flew in 241 soldiers on the edge of Qubah and heavy street fighting ensued as artillery fire provided cover firing into the surrounding palm groves. At the same time, a convoy of 19 Humvees, two Bradley fighting vehicles and several other vehicles were coming from the opposite end. The soldiers encountered several machine gun nests in the town. Some of the fighting was almost hand to hand. The Apaches occasionally strafed insurgent positions with cannons and sent Hellfire missiles into buildings soldiers were attacking from the ground. By sunset 16 insurgents were killed and 3 American soldiers were wounded in the initial clashes. But more fighting happened as the convoy tried to return to base. They were hit two times by roadside bombs. The Apaches identified the trigermen and killed up to 12 more insurgents. In one bomb blast 4 American soldiers were killed and 2 were wounded. By the close of the operation on March 24 only the town of Zaganiya was left as the last insurgent stronghold in the Baquba river valley.
On March 29, three suicide bombers in a coordinated attack on the mostly Shia town of Khalis killed 53 people and wounded 103. This coincided with a double suicide bombing in Baghdad on the Shaab area marketplace that killed 82 people, including many women and children, and wounded 138 others.
Diyala cut off, sectarian war intensifies
By early April it was reported that insurgents had taken control of the roads between Diyala and Baghdad. Large swaths of territory were in insurgent hands and the U.S. military was stretched thin. Meanwhile sectarian warfare intensified in the province with a total of 62 bodies being recovered between April 3rd and 7th. Most of the sectarian killings is done in revenge because after the mass killings of Sunnis by Shiites in Baghdad a large number of Sunnis fled to seek refuge in Baquba. That contributed to the ranks of the Sunni insurgents and also brought a greater sense of hatred toward the Shi'a population of Diyala. Also, even before Baghdad Security Plan, the Shi'a dominated military and police units in Diyala were conducting mass killings of Sunnis. Now, as Diyala has become a new safe haven for Sunni insurgents, like Al Anbar province which has already been overrun by the insurgents, that has changed were the Sunnis are striking back at the Shiites.
Because of the crackdown in Baghdad, many Shiite Mahdi Army units fled from the capital to Diyala where they took up positions in the western parts of the province and carried out attacks against American and Iraqi military targets.
5th Squadron, 73rd Cavalry Regiment under fire
One of the American units that took on the most casualties during the campaign was the 5th Squadron, 73rd Cavalry Regiment of the 82nd Airborne Division. The squadron came to Iraq at the beginning of September 2006 with 330 men, but half-way through their deployment almost 100 men from the original roster had been killed or wounded, all in the province of Diyala. By April 23, the squadron lost 20 soldiers to hostile action in the province and more than 80 had been wounded. They took part in the bloody Battle of Turki before the campaign and had been constantly under hit-and-run attacks later on. 5th Sq 73rd Cav was then augmented with an Infantry Company from 2nd Bn 35th Infantry Regiment stationed out of Schofield Barracks, HI. Together they were known as Task Force 300. TF 300 conducted combat operations clearing the Diyala River Valley of AQIZ and IISI forces. With that the squadron became the only squadron of the U.S. Army to lose almost a third of its force in the Iraq war. By May 11, 2007 the U.S commander in Diyala Maj. Gen. Benjamin Mixon said he needed more reinforcements, his current forces being unable to prevent further insurgent expansion and drive them from their stronghold of Baqubah. By mid-2007 the Islamic State of Iraq, already holding Baqubah and most of the province under its control, declared its capital to be Baqubah. By now there was already strong evidence that the Islamic State of Iraq had moved most of its command and control operations to Diyala.
Operation "Arrowhead Ripper"
In mid-June the U.S. mounted an offensive against Baghdad's northern and southern flanks. In the north an operation dubbed "Arrowhead Ripper" was started with air assaults under the cover of darkness in Baqubah. Heavy street fighting lasted throughout the first day of the operation, mainly in the center of the city and around the main city market. On the first day of the operation 22 insurgents and one U.S. soldier were killed. The next week saw U.S. forces trying to take Baqubah back from the insurgents. The attack on the city came from the west but was complicated by a maze of booby-trapped houses. It took the Americans a week before they secured 80 percent of the western section of the city. The insurgents already had intelligence that the U.S. army was going to attack the city and evacuated up to 80 percent of its principal leadership long before the operation.
After a month of street battles the fighting ceased in large parts of the city but the town of Al Khalis, approx. 15 km to the north, seemed to have become a major restaging point for insurgents retreating form Baqubah, despite the nearby presence of significant US forces at FOB Grizzly and People's Mujahedin of Iran personnel at "Ashraf City". By July 9, the focus of operations seemed to have shifted to the Baghdad-Baqubah road SW of the town.
On August 19, operation Arrowhead Ripper ended and Baqubah was largely secured by Coalition forces but still some insurgent presence remained in the city and surrounding areas but not in such large numbers as it was before the attack on the city.
Al-Qaeda strikes back
On September 24, a suicide bomber attacked a meeting of Iraqi high-level officials of Diyala province in Baquba. The attacker detonated a suicide belt inside the Shifta Shiite mosque in western Baquba during the daily breaking of the Ramadan fast. In all 28 people were killed and 50 were wounded. Among the dead were Baquba police Chief Ali al-Deylan and Brig. Gen. Abdul Karim al-Obaidi, commander of Diyala's police operations. Another slain official was Ahmed al-Tamimi, the head of the local Shiite Endowment, which administers Shiite religious facilities in the province. Two guards of the Diyala's Shiite governor, Raad Rashid Mullah Jawad, were killed. The governor himself was wounded and one of the dead guards was his brother. The dead also included Sheik Ahmed al-Tamer and Sheik Kanaan al-Faraj, both leaders of two former insurgent groups who became U.S.-allied Iraqi militias.
The campaign ends
By the beginning of October most of the heavy fighting had ended and the U.S. and Iraqi forces managed to clear out all remaining insurgent fighters out of the Diyala river valey. The American and Iraqi forces were in a position where they had not been for some time. They held most of the province and the remaining insurgent forces were in full retreat to the north and west, toward the cities of Kirkuk, Mosul, Baiji and Samara. For most of the campaign, until operation Arrowhead Ripper, the insurgents were always one step ahead of the Americans and their Iraqi counterparts and the coalition troops were at a disadvantage. But after Arrowhead Ripper was conducted and the capital city of the province, Baqubah, which was also the headquarters of the insurgent forces in the province, fell to coalition forces mid-August the tide turned and the insurgents were no longer in a position to adequately coordinate the fight. After almost eight months under insurgent control Baqubah was once again in coalition hands and in a month and a half all of the insurgent-held positions in the province crumbled before the coalition's advance. In the end the coalition managed to win an important strategic victory to secure the north-eastern flank of the capital, Baghdad, where heavy street fighting continued.
The campaign's results came at a high price for both sides. More than 425 U.S. and Iraqi troops were killed during the fighting, including the Iraqi police commander of the province. Around 1,070 insurgents were killed and around 500 were captured, more than three quarters of the whole insurgent force that was present in the province during the campaign. The number of coalition troops that were wounded, both U.S. military and Iraqi police and military, was at least 2,000. With that at least 10% of the overall coalition force present during the campaign was put out of action.
Despite coalition claims that most of the province was secure, in reality a large part of the province came under the control of the 1920 Revolution Brigade, a former insurgent group that fought against the American military. The group switched sides in June, to become a U.S.-allied Iraqi militia, who were dubbed "concerned citizens" by the Americans. Most of the group's members are former members of Saddam's army and Ba'ath party, thus it is uncertain what will come out of the alliance that the coalition forces made with the militia.
Al-Qaeda forces in Diyala had been crippled and they were no longer able to take and hold territory or wage war on the same scale as they previously enjoyed. However, some Al-Qaeda in Iraq cells remained in the province to continue to harass the Iraqi security forces and U.S. soldiers. This was evident when on October 27, a suicide bomber attacked a police base in Baqubah killing 28 Iraqi policemen and police recruits. Also, a day before that, insurgents captured in Baghdad 11 pro-US Iraqi tribal leaders, all from Diyala. Eight of the sheiks were later rescued. Three of their kidnappers were killed and four others detained in a bold rescue. Police also found the bullet-riddled body of one of the sheiks, about 50 yards (46 m) away from where the ambush took place. On the same day that the bomber attacked the police base 20 decapitated corpses were found in a village near Baqubah. These guerrilla tactics by remaining Al-Qaeda forces means that while the larger battle for overall control has already been won by the Iraqi and Coalition Forces, Diyala is still a contested province and is far from pacified.
After Coalition troops entered previously insurgent-held territories of the province they started to find in November large numbers of mass graves, mostly around Baqubah, which contained anywhere from 10 to 20 bodies. It was believed that the victims were civilians picked up by Al-Qaeda elements at check-points while Al-Qaeda was in control of the area. The bodies of more than 100 people were found in just one week. By late April 2008, more than 500 bodies were recovered.
In January 2008 the Multinational Force Iraq and New Iraqi Army launched a new offensive (codenamed Operation Phantom Phoenix) in the region to eradicate the remaining insurgents in Diyala and the neighboring Salah ad Din Governorate.
