The operation succeeded in its aim of reducing French influence in Oman and in dissuading the political forces in the region from encouraging attacks on British shipping, but it was unable to totally halt Al Qasimi activity in the Persian Gulf. By 1811, when much of the Royal Navy and HEIC forces in the Indian Ocean were diverted to Java, the Al Qasimi returned in force, although their destructive actions were weaker than before and rarely strayed into the Arabian Sea. Ultimately, it was not until the forces of the Ottoman Empire seized Medina in 1812, that some measure of control could be exerted over the tribes of the Arabian peninsula. Subsequent British intervention, both military and diplomatic, also reduced the threat of attacks during the nineteenth century.
