Very early in the day the left flank of the position had been entirely exposed by the retirement of the Portuguese, so that during the whole long and desperate struggle the general formation of the division was in the shape of an L, the shorter arm being their proper front, and the longer one facing north and holding up the German attack from inside the old lines. The northern defensive flank does not seem to have been entirely improvised, as some precautions of this nature had already been taken. The new front extended from the hamlet of Loisne upon the {231} stream of that name, through a second hamlet called Le Plantin, and so down to the canal. The first strain of the fighting fell chiefly upon the 165th Brigade (Boyd-Moss), consisting of three battalions of the famous King's Liverpool Regiment. The 6th and 7th Battalions were in the line with the 5th in support at Gorre, but as the day wore on and the pressure increased, units from both the other brigades were drawn into the fight, so that all participated in the glory of the victory. By 8.30 the flank was entirely naked, and the Germans in small but audacious bodies, with a constant rattle of rifle and machine-gun fire, were pushing in between the outer posts of the British division, overwhelming and obliterating some of them by a concentrated fire of trench mortars. Some of these isolated garrisons held out in the most desperate fashion, and helped to take the pressure off the main village line. One particularly brilliant example was that of Captain Armstrong of the 1/4th South Lancashires, who with A Company of that battalion defended a moated farm, literally to the death, having been warned that it was a key position.
