captured by the Al Qasimi, while a sharp engagement with Sultan's Dubai allies resulted in 10 dead on the Abu Dhabi side. A caravan of 50 camels carrying dates was captured and, while Abu Dhabi was reduced to dire straits by the blockade, moves against Dubai's supporters by land and the necessity to bring water and supplies from Sharjah and Ras Al Khaimah meant the blockading force also suffered. A short-lived peace was arranged, followed by a more enduring arrangement in 1834 under which Abu Dhabi agreed that the people of Dubai should be subjects of Sharjah. Perpetual Maritime Truce of 1853 The war, the most enduring and damaging so far of any between the coastal communities of the Persian Gulf, prepared the ground for the Perpetual Maritime Truce of 1853, commencing with a series of treaties negotiated by the British to cover a truce for the annual pearling season, which took effect from 1835 onwards. These annual treaties lasted for eight months each but the third treaty, at the insistence of Sultan bin Saqr, was extended to a full year and subsequent treaties to 1882 were annual. At this point, it was proposed to extend the treaty to a duration of ten years and this, broadly, held (there are several instances of squabbling and jostling on the pearl banks). Subsequently, in May 1853, the Sheikhs signed the Perpetual Maritime Truce, three of them signing as 'Chief' of their towns (Umm Al Qawain, Ajman and Dubai) and two, Saeed bin Tahnoon and Sultan bin Saqr signing as head of their tribes - Bani Yas and Al Qasimi respectively. Agreement with Muscat Ending almost a century of on and off conflict with Muscat, Sultan Bin Saqr in 1850 agreed a compromise with the Sultan of Muscat in which Al Qasimi rule was agreed north of the line between Sharjah and Khor Kalba on the East coast, but excluding the rough, high land North of the line between Sha'am on the West and Dibba on the East coast. The Siege of Hamriyah A blood-feud broke out in Sharjah between members of the Huwalah and Shwaihiyin tribes in Sharjah and Sultan moved the Shwaihiyin, a body of recent immigrants to Sharjah who numbered some 500 fighting men, to Hamriyah, a town on the northern border between Ajman and Sharjah. This provoked the first of what would be many rebellions by Hamriyah against Al
