Having established the Al Bu Falasah in Dubai, Maktoum proceeded to consolidate his position, taking over entirely when Obeid bin Said died of old age in 1836. The settlement expanded, with the natural port in the area near the Al Fahidi Fort providing a wharfage for trading vessels as well as pearling boats. Khalifa bin Shakhbut of Abu Dhabi was in favour of punishing Dubai for the nature of the Maktoums' secession and in May 1838 led a raid against the town when its pearling fleet had departed for the season's fishing. The raiding party invested a watchtower in Dubai which was the scene of fierce fighting, eventually retaken by Dubai forces but completely destroyed in the process. In 1840, Maktoum actively encouraged Saqr bin Sultan Al Qasimi, the
Wali of Sharjah, to declare independence from his father Sultan bin Saqr Al Qasimi, the ruler of
Ras Al Khaimah and head of the Qawasim federation. In this, his aim was the creation of a friendly buffer state between Dubai and the aggressive Sultan bin Saqr. Saqr bin Sultan was eventually deposed and taken to Ras Al Khaimah but escaped and sought refuge in Dubai. Sultan bin Saqr, enraged by Saqr's escape to Dubai, agreed with Khalifa bin Shakhbut of Abu Dhabi on the destruction of Dubai. Sultan then invited
Abdulla bin Rashid Al Mualla of Umm Al Quwain to join the coalition against the town. Faced with almost certain ruin, Maktoum offered Sultan bin Saqr his submission and 1,000 dollars and Sultan not only abandoned his plan, but reinstated Saqr bin Sultan as
Wali of Sharjah. A substantial majority of the
Al Bu Muhair tribe became dissatisfied with Maktoum's rule, with some 500 removing themselves from Dubai to settle in Sharjah in 1841. Following their departure and that of the fleet for the pearling season, Dubai was hit with a violent outbreak of fever, which saw many of its people fleeing across the creek to settle temporarily in
Deira, then under Sharjah's rule, with Saqr bin Sultan's blessing. The town of Bur Dubai itself being virtually abandoned, Khalifa bin Shakhbut fell on it with a force of some 150 men, plundering the town and destroying date plantations and food stores as well as firing any boats his men came across. Maktoum raised a force including 200 men from Sharjah but, following the occupation of
Jumeirah, Khalifa's forces looted the Sharjah town of
Al Khan and captured 15 slaves before his victorious army returned to Abu Dhabi. Khalifa then raised another army to move northwards, aiming to take Dubai and Sharjah but they were met with a combined force and Khalifa's camel was shot out from under him. Beaten back, Khalifa sued for peace with Maktoum and the two reconciled. By 1843 the two rulers were close friends and allies. Perhaps encouraged by his new-found friend, Khalifa went to war with the tribes of the interior, particularly the
Bani Qitab,
Ghafalah and
Na'im. Supporting Khalifa's successful raid and sack of the interior town of Dhaid, Maktoum led his forces against the Ghafalah and put them to flight, losing an eye in the process. Khalifa had established primacy over the interior tribes by 1844, when he brought together a gathering of them at
Buraimi in the summer. The
Omani Walis of both
Sohar and
Shinas, as well as representatives of the interior tribes, presented themselves. Maktoum, invited to settle with the Ghafalah, sent
Saeed bin Butti, his brother, to the negotiations - fearful of his own safety. == Trucial relations ==
