Siege of Medina  Medina, an Islamic holy city in Arabia, underwent the longest siege during World War I. Medina was at the time part of the Ottoman Empire. In the war, the Ottoman Empire sided with the Central Powers. Sharif Hussain of Mecca revolted against the caliph and the Ottoman Empire which, under the leadership of the nationalistic Young Turks, had ignored the wishes of the Caliph and sided with the Central Powers. Hussain instead sided with the British Empire. Lawrence was instrumental in this revolt. Hussain occupied Mecca and besieged Medina. It was one of the longest sieges in history that lasted until even after the armistice (10 January 1919). Fahreddin Pasha was the defender of Medina. Some celebrated him as ""the Lion of the Desert"" despite the suffering of those who remained in Medina. The siege lasted two years and seven months. In June 1916 Sharif Hussain, the Hashemite ruler of Mecca revolted against the Ottoman Empire which, under the rule of the Young Turks, had by that time begun movement towards ethnic nationalism and was marginalizing the office of the Caliph. Hussain wanted to move north and create an Arab state from Yemen to Damascus and establish a Hashemite Caliphate. Medina was, at the time, deemed important in that regard and was connected to the Ottoman Empire through a railway line. Hussain's forces besieged Medina, beginning in 1916 and lasting till January 1919. With British support, an initial attack led by Hussein's son Feisal was launched against Medina in October 1916; however, the Arabs were repulsed with heavy losses by the Turks, who were heavily-entrenched and armed with artillery, which the Arabs lacked. As the Arab Revolt slowly spread northwards along the Red Sea (ultimately culminating in the seizure of Aqaba), British and Arab strategy for capturing Medina changed, and Faisal and his advisers were determined that the Arabs would gain an advantage by leaving Medina unoccupied; this would force the Turks to retain troops to defend Medina, and to protect the Hejaz Railway, the only means of supplying the city. For this purpose, Nuri as-Said set about creating military training camps in Mecca under the direction of General 'Aziz 'Ali al-Misri. Using a mix of Bedouin volunteers, Arab officers and Arab Ottoman deserters who wanted to join the Arab Revolt, 'Aziz 'Ali created three infantry brigades, a mounted brigade, an engineering unit, and three different artillery groups made up of a patchwork of varying cannon and heavy caliber machine guns.
