At two p.m. the 12th Infantry Brigade attacked in the direction of Chivres and Vregny with the object of securing the high ground east of Chivres, as a necessary preliminary to a further advance northwards. This attack made good progress, but at 5.30 p.m. the enemy's artillery and machine-gun fire from the direction of Vregny became so severe that no further advance could be made. The positions reached were held till dark. The pontoon bridge at Venizel was completed at 5.30 p.m., when the 10th Infantry Brigade crossed the river and moved to Bucy Le Long. The 19th Infantry Brigade moved to Billy-sur-Aisne, and before dark all the artillery of the division had crossed the river, with the exception of the heavy battery and one brigade of field artillery. During the night the positions gained by the 12th Infantry Brigade to the east of the stream running through Chivres were handed over to the 5th Division. The section of the bridging train allotted to the Third Corps began to arrive in the neighbourhood of Soissons late in the afternoon, when an attempt to throw a heavy pontoon bridge at Soissons had to be abandoned, owing to the fire of the enemy's heavy howitzers. In the evening the enemy retired at all points and entrenched himself on the high ground about two miles north of the river, along which runs the Chemin-des-Dames. Detachments of infantry, however, strongly entrenched in commanding points down slopes of the various spurs, were left in front of all three corps, with powerful artillery in support of them. During the night of the 13th and on the 14th and following days the field companies were incessantly at work night and day. Eight pontoon bridges and one foot bridge were thrown across the river under generally very heavy artillery fire, which was incessantly kept up on to most of the crossings after completion. Three of the road bridges, _i.e._, Venizel, Missy, and Vailly, and the railway bridge east of Vailly were temporarily repaired so as to take foot traffic, and the Villers Bridge made fit to carry weights up to six tons. Preparations were also made for the repair of the Missy, Vailly, and Bourg Bridges, so as to take mechanical transport. The weather was very wet and added to the difficulties by cutting up the already indifferent approaches, entailing a large amount of work to repair and improve. The operations of the field companies during this most trying time are worthy of the best traditions of the Royal Engineers. 4. On the evening of the 14th it was still impossible to decide whether the enemy was only making a temporary halt, covered by rearguards, or whether he intended to stand and defend the position. With a view to clearing up the situation, I ordered a general advance.
