アングロ＝イラク戦争
On 6 May, the Luftwaffe ordered Colonel Werner Junck to take a small force to Iraq, to operate out of Mosul. Between 10 and 15 May the aircraft arrived in Mosul via Vichy French airbases, in Syria, and then commenced regular aerial attacks on British forces. The arrival of these aircraft was the direct result of fevered consultations between Baghdad and Berlin in the days following RAF strikes on the Iraqi forces above Habbaniya. The Luftwaffe force, under the direction of Lieutenant General Hans Jeschonnek, was named "Flyer Command Iraq" (Fliegerführer Irak) and was under the tactical command of Colonel Junck.
By 10:00 Kingstone arrived with reinforcements, from Habbaniya, who were immediately thrown into battle. The newly arrived infantry companies, of the Essex Regiment, methodically cleared the Iraqi positions house-by-house. By 18:00 the remaining Iraqis had fled or were taken prisoner, sniper fire was silenced, six Iraqi light tanks were captured, and the town was secure. On 23 May, aircraft of Fliegerführer Irak made a belated appearance. British positions at Fallujah were strafed on three separate occasions. But, while a nuisance, the attacks by the Luftwaffe accomplished little. Only one day earlier an air assault coordinated with Iraqi ground forces might have changed the outcome of the counter-attack.
On 8 April, Winston Churchill contacted Leo Amery, Secretary of State for India, and asked him what force could be quickly sent from India to Iraq. Amery contacted General Auchinleck and Lord Linlithgow, Viceroy and Governor-General of India, the same day. The response from India was that most of a brigade group due to set sail for Malaya on 10 April, could be diverted to Basra and the rest sent ten days later; 390 British infantry could be flown from India into RAF Shaibah and when shipping was available, the force could quickly be built up to a division. On 10 April this offer was accepted by London, and the move of these forces was codenamed.
The Chiefs-of-Staff accepted full responsibility for the dispatch of troops to Iraq.
On 8 May a column of the Arab Legion, under Glubb Pasha, reached the fort at Rutbah. They picketed the ground surrounding the fort, to wait the RAF bombardment. The fort was defended by approximately 100 policemen, the majority of them being Iraqi Desert Police. The H4-based Blenheims of 203 Squadron arrived and bombed the fort, and thinking that they had surrendered, left. The fort did not surrender and the RAF returned twice that day to bomb the fort without success.
The next day, the RAF continued to bomb the fort at intermittent intervals.
At this point in the Second World War, the situation developing in Iraq did not figure highly in British priorities. Churchill wrote, "Libya counts first, withdrawal of troops from Greece second. Tobruk shipping, unless indispensable to victory, must be fitted in as convenient. Iraq can be ignored and Crete worked up later."
The British Chiefs-of-Staff and the Commander-in-Chief for India, General Claude Auchinleck, were in favour of armed intervention but the three local commanders, already burdened by the ongoing Western Desert Campaign, East African Campaign and the Battle of Greece, suggested that the only force available was an infantry battalion in Palestine and the aircraft already in Iraq.
Initially, the Iraqi siege of RAF Habbaniya and the ability of the besieged British force there to withstand the siege was the primary focus of the conflict. Air Vice-Marshal Smart's decision to strike at the Iraqi positions with air power not only allowed his force to withstand the siege, but to neutralise much of Iraq's air power. While the relief force from Palestine arrived in Habbaniya after the siege was over, it did allow an immediate change over to the offensive.
Wilson's primary task was "to secure at all costs from land and air attack the oil fields and oil installations in Persia and Iraq." His secondary task was "to ensure the transport from the Persian Gulf ports of supplies to Russia to the maximum extent possible without prejudicing [his] primary task."
While Rashid Ali and his supporters were in alliance with the Fascist Regime in Italy the war demonstrated that Iraq's independence was at best conditional on British approval of the government's actions. Rashid Ali and the Mufti of Jerusalem fled to Persia, then to Turkey, then to Italy, and finally to Berlin, Germany, where Ali was welcomed by Hitler as head of the Iraqi government-in-exile.
The two Iraqi forces met around 5マイル (8.0 km) east of Habbaniya on the Fallujah road. The reinforcing Iraqi column was soon spotted and 40 aircraft from RAF Habbaniya arrived to attack; the two Iraqi columns were paralysed and within two hours, more than 1,000 Iraqi casualties were inflicted and further prisoners were taken. Later in the afternoon Iraqi aircraft carried out three raids on the airbase and inflicted some damage.
The British forces from Habbaniya pressed on to Baghdad after the defence of Fallujah. Major-General Clark decided to maintain the momentum because he suspected that the Iraqis did not appreciate just how small and vulnerable his forces actually were. Clark had a total of about 1,450 men to attack at least 20,000 Iraqi defenders. However, Clark did enjoy an advantage in the air.
He was also tasked with integrating Fliegerführer Irak with Iraqi forces in operations against the British. On 15 May, he flew from Mosul to Baghdad. On its approach to Baghdad, the aircraft was engaged by Iraqi ground fire, and von Blomberg was killed.
At this time, Germany and the Soviet Union were still allies (due to the Molotov–Ribbentrop Pact of 1939) and this was reflected in Soviet actions regarding Iraq. On 12 May, the Soviet Union recognised Rashid Ali's "National Defence Government." An Iraqi-Soviet exchange of notes established diplomatic relations between the two governments.
