The battle began at 5.20 in the morning of October 17. The left of the American line had its jumping-off place in the partially destroyed village of St. Souplet, and it was no easy matter to get forward from the beginning. None the less the whole line fought its way across the stream and up to the high railway embankment beyond. This, as in the area of the Thirteenth Corps, proved to be a very formidable obstacle, the more so as the fog made cohesion of attack and accurate observation equally impossible. Bandoval Farm on the left of the line poured out a destructive volume of machine-gun fire, but it was eventually rushed by the American Infantry. The right of the Twenty-seventh Division got the village of Arbre Guernon. The difficulties of this unit were greatly increased by the fact that their tanks could not ford the stream, and though it had been arranged that they should join them from the south, where there was a crossing, only two did eventually arrive, both of which were destroyed by shell-fire. In spite of everything, however, the Twenty-seventh Division fought their way forward to the Le Cateau-Arbre Guernon {184} Road, where they finally halted, as both of their flanks were, for the moment, in the air. The Thirtieth American Division had encountered a fierce resistance from the start at the villages of Molain and St. Martin, so that they were held up in crossing the river. After taking these villages they were faced by heavy fire from the ridge across the river. They formed a defensive flank, however, up to the point which their comrades had reached on the left. The total achievement of the Second American Corps was a fine one, for their prisoners amounted to nearly 1500 men, while their front had been advanced for 4000 yards. [Sidenote: Oct. 18.] Next morning, October 18, the attack was renewed by General Read, the Thirtieth Division bringing up the 60th Brigade which had been in reserve on the day before. In front of it was a line of well-fortified villages, two of which, Ribeauville and Ecaillon, were captured before evening, while a third, Mazinghien, was ringed round and American patrols were in the streets. This success represented a further advance of 1500 yards. The last-named village was completely cleared by the bayonet on the morning of October 19 and the advance was carried on for a further distance of 3000 yards. The objective of this day's attack was the high ground overlooking the Canal, and by night the west slope of this ridge had been reached all along the divisional front.
