The 1st Corps and the cavalry advanced on the river. The First Division was directed on Chanouille, viâ the canal bridge at Bourg, and the Second Division on Courteçon and Presles, _viâ_ Pont-Arcy and on the canal to the north of Braye, _viâ_ Chavonne. On the right the cavalry and First Division met with slight opposition, and found a passage by means of the canal which crosses the river by an aqueduct. The Division was, therefore, able to press on, supported by the Cavalry Division on its outer flank, driving back the enemy in front of it. On the left the leading troops of the Second Division reached the river by nine o'clock. The Fifth Infantry Brigade were only enabled to cross, in single file and under considerable shell fire, by means of the broken girder of the bridge which was not entirely submerged in the river. The construction of a pontoon bridge was at once undertaken, and was completed by five o'clock in the afternoon. On the extreme left the 4th Guards Brigade met with severe opposition at Chavonne, and it was only late in the afternoon that it was able to establish a foothold on the northern bank of the river by ferrying one battalion across in boats. By nightfall the First Division occupied the area Moulins-Paissy-Geny, with posts in the village of Vendresse. The Second Division bivouacked as a whole on the southern bank of the river, leaving only the Fifth Brigade on the north bank to establish a bridge head. The Second Corps found all the bridges in front of them destroyed, except that of Condé, which was in possession of the enemy, and remained so until the end of the battle. In the approach to Missy, where the 5th Division eventually crossed, there is some open ground which was swept by heavy fire from the opposite bank. The 13th Brigade was, therefore, unable to advance; but the 14th, which was directed to the east of Venizel at a less exposed point, was rafted across, and by night established itself with its left at St. Marguérite. They were followed by the 15th Brigade, and later on both the 14th and 15th supported the 4th Division on their left in repelling a heavy counter-attack on the Third Corps. On the morning of the 13th the Third Corps found the enemy had established himself in strength on the Vregny Plateau. The road bridge at Venizel was repaired during the morning, and a reconnaissance was made with a view to throwing a pontoon bridge at Soissons. The 12th Infantry Brigade crossed at Venizel, and was assembled at Bucy Le Long by one p.m., but the bridge was so far damaged that artillery could only be manhandled across it. Meanwhile the construction of a bridge was commenced close to the road bridge at Venizel.
