[Sidenote: March 23.] It was soon clear on the morning of March 23 that the Butt position on the right could not be maintained. The French had taken it over, but they were unable to hold it. A line was built up near Noreuil, where the remains of the 8th and 3rd Londons, aided by some French details, endeavoured all day to check the German advance. The main attacks were driving down from the north, and were heralded by a very severe machine-gun barrage, which rained bullets over the British position. The defence was much aided by a French armoured car upon the Quessy-Rouez road, and by a battery of 75's. The 4th London were to the south of the village and less exposed to the force of the advance. About six, after an hour of intense shelling, the Germans closed in upon Noreuil, the defenders, after a stout resistance which occasionally came to hand-to-hand fighting, being driven westwards. Colonel Burt, commanding the 6th Cavalry Brigade, barricaded his headquarters in the village and held the Germans off a long time by his deadly fire. It was not until long after the lines had been withdrawn that this brave officer had to be specially summoned to leave his post and fall back on Chauny. Finally, the retreat became general, but was rallied at the end of the Noreuil valley, where {183} some 200 men collected, and with a good field of fire to help them, remained for some time on the defence. Late at night this small force was ordered to fall back to a new line at Chauny. It has already been stated that two companies (C and D) of the 8th London (Post Office Rifles) had been cut off when the Germans got across the lock gate on the afternoon of March 22. These men, under Captain Gunning, had made a remarkable defence, crawling out with Lewis guns on to the lock gates in order to enfilade the advancing Germans. In the afternoon of March 23 they found themselves with the Germans on three sides of them and the canal on the fourth. Captain Gunning and Captain Kelly with the survivors then fought their way through to Condren, where they still continued their resistance. These soldiers, who made so admirable a resistance, were largely men who had been combed from the Army Service Corps.
