8th October, 1914.

My Lord,
I have the honour to report the operations in which the British Forces in France have been engaged since the evening of the 10th September.

1. In the early morning of the 11th the further pursuit of the enemy was commenced; and the three Corps crossed the Ourcq practically unopposed, the Cavalry reaching the line of the Aisne River; the 3rd and 5th Brigades south of Soissons, the 1st, 2nd and 4th on the high ground at Couvrelles and Cerseuil.

On the afternoon of the 12th from the opposition encountered by the 6th French Army to the west of Soissons, by the 3rd Corps south-east of that place, by the 2nd Corps south of Missy and Vailly, and certain indications all along the line, I formed the opinion that the enemy had, for the moment at any rate, arrested his retreat and was preparing to dispute the passage of the Aisne with some vigour. South of Soissons the Germans were holding Mont de Paris against the attack of the right of the French 6th Army when the 3rd Corps reached the neighbourhood of Buzancy, southeast of that place. With the assistance of the Artillery of the 3rd Corps the French drove them back across the river at Soissons, where they destroyed the bridges. The heavy artillery fire which was visible for several miles in a westerly direction in the valley of the Aisne showed that the 6th French Army was meeting with strong opposition all along the line.

On this day the Cavalry under General Allenby reached the neighbourhood of Braine and did good work in clearing the town and
the high ground beyond it of strong hostile detachments. The Queen's Bays are particularly mentioned by the General as having assisted greatly in the success of this operation. They were well supported by the 3rd Division, which on this night bivouacked at Brenelle, south of the river. The 5th Division approached Missy, but were unable to make headway. The 1st Army Corps reached the neighbourhood of Vauxcere without much opposition. In this manner the Battle of the Aisne commenced.

2. The Aisne Valley runs generally East and West, and consists of a flat-bottomed depression of width varying from half a mile to two miles, down which the river follows a winding course to the West at some points near the southern slopes of the valley and at others near the northern. The high ground both on the north and south of the river is approximately 400 feet above the bottom of the valley and is very similar in character, as are both slopes of the valley itself, which are broken into numerous rounded spurs and re-entrants. The most prominent of the former are the Chivre spur on the right bank and Sermoise spur on the left. Near the latter place the general plateau on the south is divided by a subsidiary valley of much the same character, down which the small River Vesle flows to the.
main stream near Sermoise. The slopes of the plateau overlooking the Aisne on the north and south are of varying steepness, and are covered with numerous patches of wood, which also stretch upwards and backwards over the edge on to the top of the high ground. There are several villages and small towns dotted about in the valley itself and along its sides, the chief of which is the town of Soissons.

The Aisne is a sluggish stream of some 170 feet in breadth, but, being 15 feet deep in the centre, it is unfordable. Between Soissons on.
the west and Villers on the east (the part of the river attacked and secured by the British Forces) there are eleven road bridges across it. On the north bank a narrow-gauge railway runs from Soissons to Vailly, where it crosses the river and continues eastward along the south bank. From Soissons to Sermoise a double line of railway runs along the south bank, turning at the latter place up the Vesle Valley towards Bazoches.

The position held by the enemy is a very strong one, either for a delaying action or for a defensive battle. One of its chief military characteristics is that from the high ground on neither side can the top of the plateau on the other side be seen except for small stretches. This is chiefly due to the woods on the edges of the slopes. Another important point is that all the bridges are under either direct or high angle artillery fire. The tract of country above described, which lies north of the Aisne, is well adapted to concealment, and was so skilfully turned to account by the enemy as to render it impossible to judge the real nature of his opposition to our passage of the river, or to accurately gauge his strength; but I have every reason to conclude that strong rearguards of at least three army corps were holding the passages on the early morning of the 13th.

3. On that morning I ordered the British Forces to advance and make good the Aisne. The 1st Corps and the Cavalry advanced on the river. The 1st Division was directed on Chanouille via the canal bridge at Bourg, and the 2nd Division on Courtecon and Presles via Pont-Arcy and on the canal to the north of Braye via Chavonne. On the right the Cavalry and 1st 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 2nd Division reached the river by 9 o'clock. The 5th 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 5 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 1st Division occupied the area Moulins-Paissy-Geny, with posts in the village of Vendresse. The 2nd Division bivouacked as a whole on the southern bank of the river, leaving only the 5th 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 Conde, 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. Marguerite. 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 1 p.m., but the bridge was so far damaged that artillery could only be man-handled across it. Meanwhile the construction of a bridge was commenced close to the road bridge at Venizel.

At 2 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. The action of the First Corps on this day under the direction and command of Sir Douglas Haig was of so skilful, bold and decisive a character that he gained positions which alone have enabled me to maintain my position for more than three weeks of very severe fighting on the north bank of the river. The Corps was directed to cross the line Moulins—Moussy by 7 a.m. On the right the General Officer Commanding the 1st Division directed the 2nd Infantry Brigade (which was in billets and bivouacked about Moulins), and the 25th Artillery Brigade (less one battery), under General Bulfin, to move forward before daybreak, in order to protect the advance of the Division sent up the valley to Vendresse. An officers' patrol sent out by this Brigade reported a considerable force of the enemy near the factory north of Troyon, and the Brigadier accordingly directed two regiments (the King's Royal Rifles and the Royal Sussex Regiment) to move at 3 a.m. The Northamptonshire Regiment was ordered to move at 4 a.m. to occupy the spur east of Troyon. The remaining regiment of the Brigade (the Loyal North Lancashire Regiment) moved at 5.30 a.m. to the village of Vendresse. The factory was found to be held in considerable strength by the enemy, and the Brigadier ordered the Loyal North Lancashire Regiment to support the King's Royal Rifles and the Sussex Regiment. Even with this support the force was unable to make headway, and on the arrival of the 1st Brigade the Coldstream Guards were moved up to support the right of the leading Brigade (the 2nd), while the remainder of the 1st Brigade supported its left.

About noon the situation was, roughly, that the whole of these two brigades were extended along a line running east and west, north of
the line Troyon and south of the Chemin-des-Dames. A party of the Loyal North Lancashire Regiment had seized and were holding
the factory. The enemy held a line of entrenchments north and east of the factory in considerable strength, and every effort to advance against this line was driven back by heavy shell and machine-gun fire. The morning was wet and a heavy mist hung over the hills, so that the 25th Artillery Brigade and the Divisional Artillery were unable to render effective support to the advanced troops until about 9 o'clock.

By 10 o'clock the 3rd Infantry Brigade had reached a point one mile south of Vendresse, and from there it was ordered to continue the line of the 1st Brigade and to connect with and help the right of the 2nd Division. A strong hostile column was found to be advancing, and by a vigorous counter stroke with two of his battalions the Brigadier checked the advance of this column and relieved the pressure on the
2nd Division. From this period until late in the afternoon the fighting consisted of a series of attacks and counter attacks. The counter strokes by the enemy were delivered at first with great vigour, but later on they decreased in strength, and all were driven off with heavy loss.

On the left the 6th Infantry Brigade had been ordered to cross the river and to pass through the line held during the preceding night by the 5th Infantry Brigade and occupy the Courtecon Ridge, whilst a detached force, consisting of the 4th Guards Brigade and the 36th Brigade, Royal Field Artillery, under Brigadier-General Perceval, were ordered to proceed to a point east of the village of Ostel. The 6th Infantry Brigade crossed the river at Pont-Arcy, moved up the valley towards Braye, and at 9 a.m. had reached the line Tilleul—La Buvelle. On this line they came under heavy artillery and rifle fire, and were unable to advance until supported by the 34th Brigade, Royal Field Artillery, und the 44th Howitzer Brigade and the Heavy Artillery. The 4th Guards Brigade crossed the river at 10 a.m. and met with very heavy opposition. It had to pass through dense woods; field artillery support was difficult to obtain; but one section of a field battery pushed up to and within the firing line. At 1 p.m. the left of the Brigade was south of the Ostel Ridge.

At this period of the action the enemy obtained a footing between the First and Second Corps, and threatened to cut the communications of the latter. Sir Douglas Haig was very hardly pressed and had no reserve in hand. I placed the Cavalry Division at his disposal, part of which he skilfully used to prolong and secure the left flank of the Guards Brigade. Some heavy fighting ensued, which resulted in the enemy being driven back with heavy loss. About 4 o'clock the weakening of the counter attacks by the enemy and other indications tended to show that his resistance was decreasing, and a general advance was ordered by the Army Corps Commander. Although meeting with considerable opposition and coming under very heavy artillery and rifle fire, the position of the corps at the end of
the day's operations extended from the Chemin-des-Dames on the right, through Chivy, to Le Cour de Soupir, with the 1st Cavalry Brigade extending to the Chavonne—Soissons road. On the right the corps was in close touch with the French Moroccan troops of the 18th Corps, which were entrenched in echelon to its right rear. During the night they entrenched this position.

Throughout the Battle of the Aisne this advanced and commanding position was maintained, and I cannot speak too highly of the valuable services rendered by Sir Douglas Haig and the Army Corps' under his command. Day after day and night after night the enemy's infantry has been hurled against him in violent counter attack which has never on any one occasion succeeded, whilst the trenches all over his position have been under continuous heavy artillery fire.

The operations of the First Corps on this day resulted in the capture of several hundred prisoners, some field pieces, and machine guns. The casualties were very severe, one brigade alone losing three of its four Colonels. The 3rd Division commenced a furtheradvance and had nearly reached the plateau of Aizy when they were driven back by a powerful counter attack supported by heavy artillery. The division, however, fell back in the best order, and finally entrenched itself about a mile north of Vailly Bridge, effectively covering the passage. The 4th and 5th Divisions were unable to do more than maintain their ground.

5. On the morning of the 15th, after close examination of the position, it became clear to me that the enemy was making a determined
stand; and this view was confirmed by reports which reached me from the French Armies fighting on my right and left, which clearly showed that a strongly entrenched line of defence was being taken up from the north of Compiegne, eastward and south-eastward, along the whole valley of the Aisne up to and beyond Reims. A few days previously the Fortress of Maubeuge fell, and a considerable quantity of siege artillery was brought down from that place to strengthen the enemy's position in front of us. During the 15th shells fell in our position which have been judged by experts to be thrown by eight-inch siege guns with a range of 10,000 yards. Throughout the whole course of the battle our troops have suffered very heavily from this fire, although its effect latterly was largely mitigated by more efficient and thorough entrenching, the necessity for which I impressed strongly upon Army Corps Commanders. In order to assist them in this
work all villages within the area of our occupation were searched for heavy entrenching tools, a large number of which were collected.

In view of the peculiar formation of the ground on the north side of the river between Missy and Soissons, and its extraordinary
adaptability to a force on the defensive, the 5th Division found it impossible to maintain its position on the southern edge of the Chivres
Plateau, as the enemy in possession of the village of Vregny to the west was able to bring a flank fire to bear upon it. The Division had, therefore, to retire to a line the left of which was at the village of Marguerite, and thence ran by the north edge of Missy back to the river to the east of that place. With great skill and tenacity Sir Charles Fergusson maintained this position throughout the whole battle, although his trenches were necessarily on lower ground than that occupied by the enemy on the southern edge of the plateau, which was only 400 yards away. General Hamilton with the 3rd Division vigorously attacked to the north, and regained all the ground he had lost on the 15th, which throughout the battle has formed a most powerful and effective bridge head.

6. On the 16th the 6th Division came up into line. It had been my intention to direct the First Corps to attack and seize the enemy's position on the Chemin-des-Dames, supporting it with this new reinforcement. I hoped from the position thus gained to bring effective fire to bear across the front of the 3rd Division which, by securing the advance of the latter, would also take the pressure off the 5th Division and the Third Corps. But any further advance of the First Corps would have dangerously exposed my right flank. And, further, I learned from the French Commander-in-Chief that he was strongly reinforcing the 6th French Army on my left, with the intention of bringing up the Allied left to attack the enemy's flank and thus compel his retirement. I therefore sent the 6th Division to join the Third Corps with orders to keep it on the south side of the river, as it might be available in general reserve.

On the 17th, 18th and 19th the whole of our line was heavily bombarded, and the First Corps was constantly and heavily engaged.

On the afternoon of the 17th the right flank of the 1st Division was seriously threatened. A counter attack was made by the Northamptonshire Regiment in combination with the Queen's, and one battalion of the Divisional Reserve was moved up in support. The Northamptonshire Regiment, under cover of mist, crept up to within a hundred yards of the enemy's trenches and charged with the bayonet, driving them out of the trenches and up the hill. A very strong force of hostile infantry was then disclosed on the crest line. This new line was enfiladed by part of the Queen's and the King's Royal Rifles, which wheeled to their left on the extreme right of our infantry line, and were supported by a squadron of cavalry on their outer flank. The enemy's attack was ultimately driven back with heavy loss.
