Factual error: In the foreground of the Akaba raid scene, Turks are using a Browning M1919 machine gun, which wasn't yet designed and certainly would not be available to the Turkish Army.

Factual error: En route westwards to Cairo, Lawrence is pictured arriving supposedly at the east bank of the Suez Canal but the direction of sunlight from the right with the Canal in the background can only mean that Lawrence has already crossed the Canal and is standing on the west bank (or on that day alone, the sun in the northern hemisphere shone from north to south???....NAH!)

Continuity: The shadows in the scene with Lawrence sleeping on his camel are short because it's the middle of the day. In the next shot you see long shadows on the sand. When Ali wakes up Lawrence they are short again.
