1st February 1915
At 12.25 pm the 15th Brigade, including the Dorsets, was relieved by the 13th Brigade, marched to Bailleul and went into billets there.
Lieutenant-Colonel Bols left the Dorsets and took over command of the 13th Brigade because its current commander, Brigadier-General Cooper, was taken ill. According to the Order of Battle of the British Army 1914 Cooper’s initials were F.J. and he took over command of the 13th Brigade on 3rd December 1914. I can’t find any mention of him anywhere else, including Ancestry. Could this be a typo and he’s actually Brigadier-General R. J. Cooper, ex-CO of 1st Grenadier Guards, who went on to lead the 29th Brigade at Gallipoli, where he was seriously wounded.
The author of 15th Brigade’s diary was very pleased with their new HQ billets. 28 Rue de Lille in Bailleul. The 1915 Trip Advisor review: “Good!”.
