In return for active campaigning effectively, Ibn Saud demanded firearms as he sought to recapture Ha'il like previous Saudi states and get revenge for his father's exile.
Yet, the British advancement in the Ottoman province of Palestine made the Saudis less relevant, while the Hashemite leader in turn concluded a peace agreement with Jabal Shammar.
Ibn Saud dispatched a warning to the Hashemites, that their presence in Turaba or advance on Khurma would provoke a war, but neither side was willing to compromise at that time.
An Ikhwan force led by Sultan bin Bajad, Hamud ibn Umar and Khalid meanwhile advanced on Turaba, and attacked the Hashemites by surprise on May 25–26 in their camp.
In the next 4 years, the Saudi ruler was preoccupied with consolidation of his domain, undertaking several campaigns in new regions of Arabia, while keeping the Hejazi frontier quiet.
Jabal Shammar was annexed in 1920–21, while Kuwait was defeated in 1922, defining the border with Iraq and Transjordan through the Uqair protocol of 1922, while simultaneously conquering Asir in south Arabia.
The key turning point was the decision by the British in late 1923 as an economy measure to cease paying subsidies to Ibn Saud and the Sharif of Mecca.
[3] Without the £60, 000 annual subsidy in gold coins paid to him by the British government, the principle reason for Ibn Saud to not invade the Hejaz was removed.
[3] The worsening relations between Britain and Hashemite rulers and the proclamation of Sharif Husayn as Caliph, finally prompted Ibn Saud to undertake the campaign, enthusiastically supported by the religiously insighted Ikhwan, who had hoped to take over the holy sites of Islam.
