[2] A naval expedition was launched with an army of 1,500 men[3] and 40 ships[4] filled with supplies and provisions, Hussain Agha and Saym Oglu were entrusted with the command of the expedition, they proceeded to Al Qunfudhah, a seaport city, and marched for seven days, the city was ruled by Asir tribe and was in the possession of Tami Bin Shu'aib, the leader of the Asir tribe,[5] it had a small garrison of five hundred men,[6] the capture of the city would open the way for the conquest of Yemen.

[7] The Ottomans besieged the city and began bombarding the walls until the garrison surrendered in March 1814 without any fight;[8][9] most of the inhabitants escaped, The city walls were fortified to defend against enemy attack but had no water supplies, and the nearest water wells were three hours away near the mountains, The Ottomans dispatched 150 Albanian troops to guard the wells; they remained in the city for one month until the Saudis launched a counter-attack led by Tami bin Shu'aib with a force of 8,000 to 10,000 men.

[10][11] The Saudis first attacked the Albanian soldiers protecting the wells; some of them fought and the rest escaped to the town.

without an attempt to defend the walls, panic struck the commanders, and they ordered the troops to retreat towards the ships.

The Ottoman commander then abandoned all who could not escape;[12][13] the ships were badly supplied with water or provisions which caused many to die of thirst on their way to Jeddah.
