Kut

Kūt (), officially Al-Kut, also spelled Kutulamare or Kut al-Imara, is a city in eastern Iraq, on the left bank of the Tigris River, about south east of Baghdad. the estimated population is about 389,400 people.
It is the capital of the province long known as Al Kut, but since the 1960s renamed Wasit.
The old town of Kut is within a sharp "U" bend of the river, opposite from the point where the Shatt al-Gharraf branches off from the Tigris. This "U"-shaped bend almost makes it an island but for a narrow connection to the shore. For centuries Kut was a regional center of the carpet trade. The area around Kut is a fertile cereal grain growing region. The Baghdad Nuclear Research Facility, looted following the 2003 US invasion of Iraq, is located near Kut.
The Kut Barrage was constructed in the city in the 1930s to provide irrigation water for the surrounding area. The barrage supports a road and includes a lock for boats passing up and down the Tigris. Its purpose is to maintain a sufficiently high water level in the Tigris to provide water for the Gharraf irrigation canal.
In 1952, were irrigated from water provided by the Gharraf Canal. Of this newly reclaimed land, was distributed to small farmers as part of a social land reform program. These farmers received per family and were required to live on the land they farmed. In 2005, repairs and maintenance works were carried out at the Kut Barrage and the Gharraf Head Regulator for a total cost of US$3 million.

History.
The medieval city of Madharaya was at the site of modern Kut. It lay at the point where the Nahrawan Canal flowed out into the Tigris. Madharaya has been identified as the hometown of the Sasanian-era Zoroastrian religious leader Mazdak. By the early 1200s, however, Yaqut al-Hamawi wrote that Madharaya was in ruins.
Modern Kut owes much of its prosperity to the advent of steamboat transportation on the Tigris in the 1800s.
World War I.
Kut was the scene of a fierce battle during World War I. The British Mesopotamian Expeditionary Force, led by Major General Charles Townshend, marched north from Basra in September 1915 in what became known as the Mesopotamian Campaign. They reached Kut on September 26, where after three days of fighting they drove the Ottoman forces from the town.
After a halt of nearly nine months, Townshend then headed up river to Ctesiphon. Following a battle there, the British forces withdrew back to Kut. On December 7, 1915, the Turks, under their commander, the Colonel Nurettin Pasha, arrived at Kut and began a siege. The British cavalry under Colonel Gerard Leachman succeeded in breaking out, but Townshend and the bulk of the force remained besieged. Many attempts were made to relieve Townshend's forces, but all were defeated. Some 23,000 British and Indian soldiers died in the attempts to retake Kut, probably the worst loss of life for the British away from the European theater. Near the end of the siege, T. E. Lawrence and Aubrey Herbert of British Intelligence unsuccessfully tried to bribe Khalil Pasha to allow the troops to escape. Townshend, with some 8,000 surviving soldiers, finally surrendered Kut on April 29, 1916. The captured soldiers were divided, where the officers were sent to separate facilities, and many of the enlisted soldiers were impressed into hard labour until the surrender of the Ottoman Empire; more than half of them died. The British went back on the offensive in December 1916 with a larger and better-supplied force under General Sir Frederick Stanley Maude and retook Kut on February 23, 1917.
Kut suffered heavy damage during the First World War, and was almost entirely rebuilt afterward.
Contingency Operating Base Delta (COB Delta).
In the early 21st century, the Contingency Operating Base (COB) Delta was an American military installation located on the right bank of the Tigris southwest from Kut. Designated as a Forward operating base (FOB) in the early stages of Operation Iraqi Freedom, Delta was centered on a former Iraqi Air Force base, Ubaydah Bin Al Jarrah Air Base. In 2005 Delta was selected to become an "enduring" FOB, remaining open after other FOBs had closed. During the Operation Iraqi Freedom, FOB Delta was 
manned by Polish, Kazakhstan, El Salvadorian, Georgian, Lithuanian, British, and US Multi-National Forces. Sometime after 2009 the FOB was re-designated as a COB. COB Delta was closed on October 24, 2011 and officially turned over to the IAF in a handover ceremony that afternoon in the main flight line hangar/terminal. Later that evening, approximately 2,200, the last Force Pro civilians flew out by helicopter.
