In early June 1916, the Ottoman government was putting pressure on Sharif Husayn to supply Hijazi troops and to issue a call for jihad from
Mecca in support of the Ottoman participation in
World War I. In exchange for the troops, Husayn wanted greater autonomy, but the Ottoman authorities would not concede it. Ottoman officials were holding Husayn's son
Faysal and told Husayn that if he ever wanted to see his son again, he must send the troops. On June 9, 1916, the Ottomans sent Faysal to
Medina to get the armed forces that Husayn had been organizing, but when he arrived, he escaped with his brother ‘Ali. At the beginning of the revolt, the Sharifian Army consisted of these forces that had been assembled by Husayn and his sons under the guise that they were to fight with the Ottoman forces. After escaping, Faysal wrote a letter stating that if Husayn's demands for greater autonomy were not met their relations with the Ottomans would end. Rather than wait for a reply, the Arab Revolt was started with an attack on the Hijaz Railway by forces that consisted of members of local Arab tribes and Ottoman defectors. The following day the first shots of the revolt were fired in Mecca and within two days, the Sharifian Army was in control of Mecca. By June 16, the Sharifian Army, with the assistance of the British
Royal Navy, captured the important port of
Jeddah. By the end of the summer, the Arab forces under the control of Sharif Husayn had managed to overtake coastal cities as far north as
Yanbu and as far south as
Qunfudhah. The Ottomans decisively won a battle for the first time when the Sharifian Army attacked Medina in October 1916. The Ottoman forces were entrenched in Medina with artillery that the poorly equipped Sharifian Army lacked. The Sharifian forces retreated and were forced to develop a new strategy in regard to Medina. Rather than attack the well-protected Ottoman army and suffer large casualties, the Arabs surrounded the city and cut it off from access to other Ottoman forces. For much of the war the Ottomans managed to keep the Hijaz Railway open to Medina and, through this, were able to continue to supply their men with weapons, ammunition, and other equipment until near the end of the war. The constant need for supplies in Medina played into the Sharifian strategy which was designed to have the Ottomans station troops along the railway and in Medina, wasting troops and supplies, while the Arabs continued up the coast of the Red Sea. As the British and Sharifian forces sought a way to overtake the Ottoman forces at
Aqaba, the British decided to send
Captain (later
Colonel)
T. E. Lawrence (commonly referred to as “Lawrence of Arabia”) to help Faysal lead his forces. Lawrence's plan was to make the Ottomans think that the Arabs were planning on attacking
Damascus by creating a few diversions, including the destruction of a railroad bridge in
Baalbek. Upon arrival in Aqaba on July 6, 1917, the Sharifian forces brutally massacred about three hundred Ottomans before their superiors could get them under control. Another 150 Ottoman troops were taken prisoner and after a few subsequent small scale attacks by Ottomans, the Arab and British forces solidified control in Aqaba. From this point onwards, the Sharifian Army fought at the side of the British armed forces that were coming from British-occupied Egypt. The well executed
Battle of Megiddo included a small amount of Sharifian forces who marched into Damascus on October 1, 1918, with their revolt almost complete. The only city still under Ottoman control in the Hijaz was the city of Medina. Although they were cut off from the rest of the Ottoman world, forces inside of Medina continued to resist Sharifian forces until their lack of supplies forced them to surrender in January 1919. ==Forces==
