Mohammed ash-Sheikh
The Portuguese installed a governor there, but they were quickly opposed by pre-existing tribes in the region who were hostile to their presence. Beginning in 1530, they were blockaded in Santa Cruz. Portuguese weakness showed itself on 12 March 1541 when Sherif Saâdien Mohammed ash-Sheikh captured the fortress of Santa Cruz de Aguer. Six hundred Portuguese survivors were taken prisoner, including the governor, Guterre de Monroy, and his daughter, Dona Mecia. The captives were redeemed by the holy men, who were mostly from Portugal. Dona Mecia, whose husband was killed during the battle, became the wife of Sheikh Mohammed ash-Sheikh but died in childbirth in 1544. In the same year, Mohammed ash-Sheikh released Guterre de Monroy, whom he had befriended.
