[2] In May 1869, Salim bin Sultan and his brother Ibrahim moved together against Humaid bin Abdullah with the intention of establishing Ibrahim as Ruler of Ras Al Khaimah, landing 1,500 men from 32 boats.
The British Resident, Colonel Lewis Pelly, on hearing of this breach of the maritime truce (the embarkation of troops in an act of war by sea breached the treaty) sailed from Lingeh in the Dalhousie with the gunboat Hugh Rose.
[3] Alliances shifted quickly, however, and in 1871 Humaid bin Abdullah, together with the Ruler of Umm Al Qawain, supported Salim bin Sultan when he took advantage of Ibrahim's absence on a journey to Abu Dhabi and cemented his ascendancy by retaking total control of Sharjah.
At the same time, Humaid bin Abdullah retook the dependencies of Sha'am, Rams and Shimal, which had managed to secede from his rule.
[3] An attempt by Sha'am to secede in 1885 resulted in Humaid extracting a fine of 1600 Marie Theresa Dollars.
