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. On the same day General Archibald Wavell, Commander-in-Chief of Middle East Command, informed London that he could no longer spare the battalion in Palestine and urged diplomacy and possibly a demonstration of air strength, rather than military intervention.
On 10 April, Major-General William Fraser assumed control over Iraqforce, the land forces from India headed for Basra with orders to occupy the Basra-Shabai area to ensure the safe disembarkation of further reinforcements and to enable a base to be established in that area. The attitude of the Iraqi Army and local authorities was still uncertain and attempts might be made to oppose disembarkation. Fraser was closely to co-operate with the navy commander. If the landing was opposed, Fraser was to defeat the Iraqi forces and establish a base, but Fraser was not to infringe Iranian neutrality. In early April, preparation for hostilities began at Habbaniya, aircraft were modified to carry bombs and light bombers such as the Audaxes were modified to carry larger bombs.
On 12 April, Convoy BP7 left Karachi. The convoy was composed of eight transports escorted by the Template:Sclass Template:HMAS. The forces transported by the convoy were under the command of Major-General Fraser, the commanding officer of the 10th Indian Infantry Division. The forces being transported consisted of two senior staff officers from the 10th Indian Division headquarters, the 20th Indian Infantry Brigade, the personnel of the Royal Artillery's 3rd Field Regiment; but without their guns, and certain ancillary troops.
On 13 April, the Royal Navy force of four ships in the Persian Gulf were reinforced by the aircraft carrier Hermes(en) and two light cruisers, Emerald(en) and Template:HMNZS. HMS Hermes carried the Fairey Swordfish torpedo bombers of 814 Squadron. The naval vessels which covered the disembarkation at Basra consisted of the aircraft carrier HMS Hermes, the light cruiser HMS Emerald, the light cruiser HMNZS Leander, the sloop Falmouth(en), the gunboat HMS Cockchafer, the sloop HMS Seabelle, the minesweeper sloop Template:Ship, and the sloop HMAS Yarra. On the morning of 15 April, Convoy BP7 was met at sea by HMS Seabelle from Basra. Later in the day the escort was reinforced by HMS Falmouth. On 17 April, the convoy was joined by HMIS Lawrence and then proceeded towards the entrance of the Shatt al-Arab. On 18 April, the convoy moved up the Shatt al-Arab and arrived at Basra at 0930 hrs. HMS Emerald was already in Basra. On the same day, HMNZS Leander was released from support duties in the Persian Gulf. On 16 April, the Iraqi Government was informed that the British were going to invoke the Anglo-Iraq treaty to move troops through the country to Palestine. Rashid Ali raised no objection.
