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.

Continuity: Lawrence & his Arab revolt are supposedly travelling up the right flank of the Army (briefing scene with blackboard) where Harry is told to get with the arab cavalry, but it's the guns that matter, which are supposed to pound the turkish centre. In the later scene where the Arab revolt is pursuing their journey up the right flank into the night, they see gun flashes in the distance and Lawrence says god help them.... he is looking over his right shoulder as he is riding, to look at the barrage. It should be his left shoulder as they are travelling with the turkish centre to their left.

Factual error: On his way to Cairo, history records that after crossing the Sinai Desert, Lawrence arrived at the sea at Akaba (which is at the northern end of the Red Sea). In the film he turns left along the beach when he should have turned right (towards the Suez Canal). The scene was shot on a Mediterranean beach in Spain (from where Cairo WOULD be on his left!)

Factual error: When Lawrence arrives at the Suez Canal, the ship which sails past is of a 1950's design, and I think actually belonged to a company called "Blue Funnel Line".

Plot hole: It's settled that Lawrence takes 50 of Prince Faisal's men with him to fight the Turks in Akaba (as long as they get there through the burning desert). But to my calculations there's only 32 men riding with him, plus those young servant wannabe's who (without permission) follow the party.
