Thomas Edward Lawrence was born on 16 August 1888 in Tremadog, Carnarvonshire (now Gwynedd), Wales in a house named Gorphwysfa, now known as Snowdon Lodge. His Anglo-Irish father Thomas Chapman had left his wife Edith after he fell in love and had a son with Sarah Junner, a young Scotswoman who had been engaged as governess to his daughters. Sarah was the daughter of Elizabeth Junner and John Lawrence, who worked as a ship's carpenter and was a son of the household in which Elizabeth had been a servant. She was dismissed four months before Sarah was born.

The chief elements of the Arab strategy, developed chiefly by Faisal and Lawrence, were firstly to avoid capturing Medina, and secondly to extend northwards through Maan and Deraa to Damascus and beyond. The Emir Faisal wanted to lead regular attacks against the Ottomans, which Lawrence persuaded him to drop. Lawrence wrote about the Bedouin as a fighting force:  "The value of the tribes is defensive only and their real sphere is guerilla warfare. They are intelligent, and very lively, almost reckless, but too individualistic to endure commands, or fight in line, or to help each other. It would, I think, be possible to make an organized force out of them...The Hejaz war is one of dervishes against regular forces-and we are on the side of the dervishes. Our text-books do not apply to its conditions at all".  Medina was an attractive target for the revolt as Islam's second-holiest site, and because its Ottoman garrison was weakened by disease and isolation. It became clear that it was advantageous to leave it there rather than try to capture it, while continually attacking, but not permanently breaking, the Hejaz railway south from Damascus. This prevented the Ottomans from making effective use of their troops at Medina, and forced them to dedicate many resources to defending and repairing the railway line.  The movement north to Damascus and eventually Aleppo is interesting in the context of the Sykes-Picot agreement. While it is not known when Lawrence learned the details of Sykes-Picot, nor if or when he briefed Faisal on what he knew, there is good reason to think that both these things happened, and earlier rather than later. In particular, the Arab strategy of northward extension makes perfect sense given the Sykes-Picot language that spoke of an independent Arab entity in Syria, which would only be granted if the Arabs liberated the territory themselves. The French, and some of their British Liaison officers, were specifically uncomfortable about the northward movement, as it would weaken French colonial claims.
