The Iraqi Air Force was equipped with a few obsolete aircraft given by the British, and a few of what it considered modern ones - but of a rather second class, like the Breda Ba.65 - some 60 in all. In April, 1941, at German urgings and with the promise of supporting Luftwaffe air units, the Iraqi government was overthrown by pro-nationalist prince of the Royal house backed by a cabal of officers (the Golden Square). The military of Iraq was thrown against the British presence, which included the British Middle East RAF training school at Habbinayah.
The most modern aircraft at Habbinayah were 9 Gladiators, everything else being older and more obsolete. Some 9,000 Iraqi ground troops and light artillery came to lay seige, but were beaten off by strafing attacks and attacks by the 400 troops airlifted in just before the seige. Began. By the time relieveing troops appeared (HabForce, coming in from Transjordan), the seige ha dalready been lifted and the beseiging force retreated.
Meanwhile, the promised Axis air support finally materialized however weakly: He111s, Bf110s and CR.42s flew into Mosul through Syria. However, supporting them by air at such a distance proved too difficult (and in the face of the collapse of the Iraqi rebellion) and the air units were withdrawn after only a couple of weeks.
