“Everyone burst out singing a full-throated song in honour of Emir Feisal and his family. The march became rather splendid and barbaric. First rode Feisal in white, then Sharraf at his right in red head-cloth and henna-dyed tunic and cloak, myself on his left in white and scarlet,
behind us three banners of faded crimson silk with gilt spikes, behind them the drummers playing a march, and behind them again the wild mass of twelve hundred bouncing camels of the bodyguard, packed as closely as they could move, the men in every variety of coloured clothes and the camels nearly as brilliant in their trappings. We filled the valley to its banks with our flashing stream.”

Events of 4 January 1917 as recounted by T. E. Lawrence in Seven
Pillars of Wisdom (1926).

On 4 January,  Feisal’s army began its advance on Wejh. Lawrence joined the army for the first leg, before turning back to ride the 22 miles to Yenbo in the late afternoon. There, he would liaise with the Navy to have supplies shipped north to the Arabs, while waiting the arrival of Colonel Stewart Newcombe to take over his liaison role.
