Though its flanks were still exposed, the 91st was told to go ahead the next day, the plan of the Army command, as we have seen, being to use all the fight there was in every division on the 28th, when our ambition still dared an immediate conquest of the whale-back after the taking of Montfaucon. Switching now to a two-regiment front, after fifteen minutes of preparation by the artillery, which was all in position, the Pacific Coast men again attacked on the third day, which, in turn, they were to find different from the second. While the guns kept moving forward and striving to lay down protecting barrages and to smash machine-gun nests, they made a mile and a half against resistance hourly becoming more vicious and determined, taking Epinonville and entering the Cierges Wood, which was to earn such a sinister reputation. Despite the general results of September 28th, which had somewhat dampened its ambition for a prompt decision, the Army command, now seeking to drive a wedge into the heights between the Aire and whale-back in order to break the chain of its covering defenses, ordered the 91st to continue attacking on the 29th. The two regiments in the rear, which had had a little rest, passed through the two that had been exhausted by the hard work in front on the 28th. Two battalions of the engineers, whose indefatigability had kept the roads in shape, were sent into line. As we know, the engineers were never allowed to be idle. If they had nothing else to do, they could fight.
