One of Khalid bin Ahmad's first acts on becoming Ruler of Sharjah was to settle the question of Jazirat Al Hamra.
[4] Khalid bin Ahmad's rule was characterised by a number of challenges, not the least of which was losing Ras Al Khaimah as a dependency.
In June 1920, Abdulrahman seized the fort of Ajman and was only removed after the intercession of the British Residency Agent.
Again, the British intervened and an agreement was made that recognised Abdulrahman as a subject of Khalid's and bound him to cause no further trouble.
Khalid then moved against Al Heera, which Abdulrahman now prepared to defend against a combined force from Sharjah and Ajman.
On 1 November 1924, Sultan bin Saqr was welcomed into Sharjah and deposed Khalid in a brief, 11-day conflict.
This ceded the fort at Dhaid and the revenues of the inland oasis town to Khalid bin Ahmad.
Dhaid, in 1906, generated some 228 Marie Theresa Dollars annually in water rates, as well as revenue from the sale of dates.
With the support of the Sheikhs of the Bedouin Bani Ka'ab and Na'im tribes, who favoured any scheme which would weaken Sharjah, it was agreed that the ruler of Ras Al Khaimah, Sultan bin Salim Al Qasimi, would possess Dhaid 'on behalf of Khaled bin Ahmad'.
[13] Khalid bin Ahmad finally took full possession of Dhaid in his own right in July 1928.
Said bin Hamad had been recognised as a Trucial Sheikh by the British in 1936 in return for his agreement to confer landing rights for a backup airstrip to support the Imperial Airways airfield in Sharjah.
