The Siege of Jeddah was a naval battle that took place in the harbor of Jeddah between a Portuguese expeditionary force under Lopo Soares de Albergaria and Ottoman elements under Selman Reis. The Portuguese fleet arrived off the city’s coast on Easter day, 1517 (April 12th), Hijri year 923, and moored in the channel. After a quick naval action that day with few casualties, shore artillery prevented the Portuguese from landing, and weather ultimately caused them to withdraw.
