The transport of the troops from England both by sea and by rail was effected in the best order and without a check. Each unit arrived at its destination in this country well within the scheduled time. The concentration was practically complete on the evening of Friday, the 21st ultimo [August], and I was able to make dispositions to move the Force during Saturday, the 22nd, to positions I considered most favourable from which to commence operations which the French Commander-in-Chief, General Joffre, requested me to undertake in pursuance of his plans in prosecution of the campaign. The line taken up extended along the line of the canal from Conde on the west, through Mons and Binche on the east. This line was taken up as follows: - From Conde to Mons inclusive was assigned to the Second Corps, and to the right of the Second Corps from Mons the First Corps was posted. The 5th Cavalry Brigade was placed at Binche. In the absence of my Third Army Corps I desired to keep the Cavalry Division as much as possible as a reserve to act on my outer flank, or move in support of any threatened part of the line. The forward reconnaissance was entrusted to Brigadier-General Sir Philip Chetwode with the 5th Cavalry Brigade, but I directed General Allenby to send forward a few squadrons to assist in this work.

During the 22nd and 23rd these advanced squadrons did some excellent work, some of them penetrating as far as Soignies, and several encounters took place in which our troops showed to great advantage.

At 6 a.m., on August 23rd, I assembled the Commanders of the First and Second Corps and Cavalry Division at a point close to the position, and explained the general situation of the Allies, and what I understood to be General Joffre's plan. I discussed with them at some length the immediate situation in front of us. From information I received from French Headquarters I understood that little more than one, or at most two, of the enemy's Army Corps, with perhaps one Cavalry Division, were in front of my position; and I was aware of no attempted outflanking movement by the enemy. I was confirmed in this opinion by the fact that my patrols encountered no undue opposition in their reconnoitring operations. The observation of my aeroplanes seemed also to bear out this estimate.

About 3 p.m. on Sunday, the 23rd, reports began coming in to the effect that the enemy was commencing an attack on the Mons line, apparently in some strength, but that the right of the position from Mons and Bray was being particularly threatened. The Commander of the First Corps had pushed his flank back to some high ground south of Bray, and the 5th Cavalry Brigade evacuated Binche, moving slightly south: the enemy thereupon occupied Binche. The right of the 3rd Division, under General Hamilton, was at Mons, which formed a somewhat dangerous salient; and I directed the Commander of the Second Corps to be careful not to keep the troops on this salient too long, but, if threatened seriously, to draw back the centre behind Mons. This was done before dark.

In the meantime, about 5 p.m., I received a most unexpected message from General Joffre by telegraph, telling me that at least three German Corps, viz., a reserve corps, the 4th Corps and the 9th Corps, were moving on my position in front, and that the Second Corps was engaged in a turning movement from the direction of Tournay. He also informed me that the two reserve French divisions and the 5th French Army on my right were retiring, the Germans having on the previous day gained possession of the passages of the Sambre between Charleroi and Namur.

In view of the possibility of my being driven from the Mons position, I had previously ordered a position in rear to be reconnoitred. This position rested on the fortress of Maubeuge on the right and extended west to Jenlain, south-east of Valenciennes, on the left. The position was reported difficult to hold, because standing crops and buildings made the siting of trenches very difficult and limited the field of fire in many important localities. It nevertheless afforded a few good artillery positions. When the news of the retirement of the
French and the heavy German tnreatehing on my front reached me, I endeavoured to confirm it by aeroplane reconnaissance; and as a result of this I determined to effect a retirement to the Maubeuge position at daybreak on the 24th.

A certain amount of fighting continued along the whole line throughout the night, and at daybreak on the 24th the 2nd Division from the neighbourhood of Harmignies made a powerful demonstration as if to retake Binche. This was supported by the artillery of both the 1st and 2nd Divisions, whilst the 1st Division took up a supporting position in the neighbourhood of Peissant. Under cover of this demonstration the Second Corps retired on the line Dour-Quarouble-Frameries. The 3rd Division on the right of the Corps suffered considerable loss in this operation from the enemy, who had retaken Mons. The Second Corps halted on this line, where they partially entrenched themselves, enabling Sir Douglas Haig with the First Corps gradually to withdraw to the new position; and he effected this without much further loss, reaching the line Bavai-Maubeuge about 7 p.m.

Towards midday the enemy appeared to be directing his principal effort against our left. I had previously ordered General Allenby with the Cavalry to act vigorously in advance of my left front and endeavour to take the pressure off.

About 7.30 a.m. General Allenby received a message from Sir Charles Fergusson, commanding 5th Division, saying that he was very
hard pressed and in urgent need of support. On receipt of this message General Allenby drew in the Cavalry and endeavoured to bring
direct support to the 5th Division. During the course of this operation General De Lisle, of the 2nd Cavalry Brigade, thought he saw a good opportunity to paralyse the further advance of the enemy's infantry by making a mounted attack on his flank. He formed up and advanced for this purpose, but was held up by wire about 500 yards from his objective, and the 9th Lancers and 18th Hussars suffered severely in the retirement of the Brigade.

The 19th Infantry Brigade, which had been guarding the Line of Communications, was brought up by rail to Valenciennes on the 22nd and 23rd. On the morning of the 24th they were moved out to a position south of Quarouble to support the left flank of the Second Corps.

With the assistance of the Cavalry Sir Horace Smith-Dorrien was enabled to effect his retreat to a new position; although, having two corps of the enemy on his front and one threatening his flank, he suffered great losses in doing so. At nightfall the position was occupied by the Second Corps to the west of Bavai, the First Corps to the right. The right was protected by the Fortress of Maubeuge, the left by the 19th Brigade in position between Jenlain, and Bry, and the Cavalry on the outer flank.

The French were still retiring, and I had no support except such as was afforded by the Fortress of Maubeuge; and the determined attempts of the enemy to get round my left flank assured me that it was his intention to hem me against that place and surround me. I felt that not a moment must be lost in retiring to another position. I had every reason to believe that the enemy's forces were somewhat exhausted, and I knew that they had suffered heavy losses. I hoped, therefore, that his pursuit would not be too vigorous to prevent me effecting my object. The operation, however, was full of danger and difficulty, not only owing to the very superior force in my front, but also to the exhaustion of the troops.

The retirement was recommenced in the early morning of the 25th to a position in the neighbourhood of Le Cateau, and rearguards were ordered to be clear of the Maubeuge-Bavai-Eth Road by 5.30 a.m. Two Cavalry Brigades, with the Divisional Cavalry of the Second Corps, covered the movement of the Second Corps. The remainder of the Cavalry Division with the 19th Brigade, the whole under the command of General Allenby, covered the west flank. The 4th Division commenced its detrainment at Le Cateau on Sunday, the 23rd, and by the morning of the 25th eleven battalions and a Brigade of Artillery with Divisional Staff were available for service. I ordered General Snow to move out to take up a position with his right south of Solesmes, his left resting on the Cambrai-Le Cateau Road south of La Chaprie. In this position the Division rendered great help to the effective retirement of the Second and First Corps to the new position.

Although the troops had been ordered to occupy the Cambrai-Le Cateau-Landrecies position, and the ground had, during the 25th, been partially prepared and entrenched, I had grave doubts—owing to the information I received as to the accumulating strength of the enemy against me—as to the wisdom of standing there to fight. Having regard to the continued retirement of the French on my right, my exposed left flank, the tendency of the enemy's western corps (II.) to envelop me, and, more than all, the exhausted condition of the troops, I determined to make a great effort to continue the retreat till I could put some substantial obstacle, such as the Somme or the Oise, between my troops and the enemy, and afford the former some opportunity of rest and reorganisation. Orders were, therefore, sent to the Corps Commanders to continue their retreat as soon as they possibly could towards the general line Vermand-St. Quentin Ribemont. The Cavalry, under General Allenby, were ordered to cover the retirement.

Throughout the 25th and far into the evening, the First Corps continued its march on Landrecies, following the road along the eastern border of the Foret De Mormal, and arrived at Landrecies about 10 o'clock. I had intended that the Corps should come further west so as to fill up the gap between Le Cateau and Landrecies, but the men were exhausted and could not get further in without rest. The enemy, however, would not allow them this rest, and about 9.30 p.m. a report was received that the 4th Guards Brigade in Landrecies was heavily attacked by troops of the 9th German Army Corps who were coming through the forest on the north of the town. This brigade fought most gallantly and caused the enemy to suffer tremendous loss in issuing from the forest into the narrow streets of the town. This loss has been estimated from reliable sources at from 700 to 1,000. At the same time information reached me from Sir Douglas Haig that his 1st Division was also heavily engaged south and east of Maroilles. I sent urgent messages to the Commander of the two French Reserve Divisions on my right to come up to the assistance of the First Corps, which they eventually did. Partly owing to this assistance, but mainly to the skilful manner in which Sir Douglas Haig extricated his Corps from an exceptionally difficult position in the darkness of the night, they were able at dawn to resume their march south towards Wassigny on Guise. By about 6 p.m. the Second Corps had got into position with their right on Le Cateau, their left in the neighbourhood of Caudry, and the line of defence was continued thence by the 4th Division towards Seranvillers, the left being thrown back.

During the fighting on the 24th and 25th the Cavalry became a good deal scattered, but by the early morning of the 26th General Allenby
had succeeded in concentrating two brigades to the south of Cambrai. The 4th Division was placed under the orders of the General Officer Commanding the Second Army Corps. On the 24th the French Cavalry .Corps, consisting of three divisions, under General Sordet, had been in billets north of Avesnes. On my way back from Bavai, which was my " Poste de Commandemeht'' during the fighting
of the 23rd and 24th, I visited General Sordet, and earnestly requested his co-operation and support. He promised to obtain sanction
from his Army Commander to act on my left flank, but said that his horses were too tired to move before the next day. Although he rendered me valuable assistance later on in the course of the retirement, he was unable for the reasons given to afford me any support on the most critical day of all, viz., the 26th.

At daybreak it became apparent that the enemy was throwing the bulk of his strength against the left of the position occupied by the Second Corps and the 4th Division. At this time the guns of four German Army Corps were in position against them, and Sir Horace Smith-Dorrien reported to me that he judged it impossible to continue his retirement at daybreak (as ordered) in face of such an attack. I sent him orders to use his utmost endeavours to break off the .action and retire at the earliest possible moment, as it was impossible for me to send him any support, the First Corps being at the moment incapable of movement. The French Cavalry Corps, under General Sordet, was coming up on our left rear early in the morning, and I sent an urgent message lo him to do his utmost to come up and support the retirement of my left flank; but, owing to the fatigue of his horses he found himself unable to intervene in any way. There had been no time to entrench the position properly, but the troops showed a magnificent front to the terrible fire which confronted them.

The Artillery, although outmatched by at least four to one, made a splendid fight, and inflicted heavy losses on their opponents. At length it became apparent that, if complete annihilation was to be avoided, a retirement must be attempted; and the order was given to commence it about 3.30 p.m. The movement was covered with the most devoted intrepidity and determination by the Artillery,
which had itself suffered heavily, and the fine work done by the Cavalry in the further retreat from the position assisted materially in the final completion of this most difficult and dangerous operation. Fortunately the enemy had himself suffered too heavily to engage in an energetic pursuit. I cannot close the brief account of this glorious stand of the British troops without putting on record my deep appreciation of the valuable services rendered by General Sir Horace Smith-Dorrien. I say without hesitation that the saving of the left wing of the Army under my command on the morning of the 26th August could never have been accomplished unless a commander of rare and unusual coolness, intrepidity, and determination had been present to personally conduct the operation.

The retreat was continued far into the night of the 26th and through the 27th and 28th, on which date the troops halted on the line Noyon-
Chauny-La Fere, having then thrown off the weight of the enemy's pursuit. On the 27th and 28th I was much indebted to General Sordet and the French Cavalry Division which he commands for materially assisting my retirement and successfully driving back some of the enemy on Cambrai. General D'Amade also, with the 61st and 62nd French Reserve Divisions, moved down from the neighbourhood of Arras on the enemy's right flank and took much pressure off the rear of the British Forces. This closes the period covering the heavy
fighting which commenced at Mons on Sunday afternoon, 23rd August, and which really constituted a four days' battle. At this point, therefore, I propose to close the present despatch.

I deeply deplore the very serious losses which the British Forces have suffered in this great battle; but they were inevitable in view of the
fact that the British Army—only two days after a concentration by rail—was called upon to withstand a vigorous attack of five German
Army Corps. It is impossible for me to speak too highly of the skill evinced by the two General Officers commanding Army Corps; the self-sacrificing and devoted exertions of their Staffs; the direction of the troops by Divisional, Brigade and Regimental Leaders; the command of the smaller units by their officers; and the magnificent fighting spirit displayed by non-commissioned officers and men.

I wish particularly to bring to your Lordship's notice the admirable work done by the Royal Flying Corps under Sir David Henderson. Their skill, energy and perseverance have been beyond all praise. They have furnished me with the most complete and accurate information which has been of incalculable value in the conduct of the operations. Fired at constantly both by friend and foe, and not hesitating to fly in every kind of weather, they have remained undaunted throughout. Further, by actually fighting in the air, they have succeeded in destroying five of the enemy's machines.

I wish to acknowledge with deep gratitude the incalculable assistance I received from the General and Personal Staffs at Headquarters
during this trying period. Lieutenant-General Sir Archibald Murray, Chief of the General Staff; Major-General Wilson, Sub-Chief of the General Staff; and all under them have worked day and night unceasingly with the utmost skill, self-sacrifice, and devotion; and the same acknowledgment is due by me to Brigadier-General Hon. W. Lambton, my Military Secretary, and the Personal Staff. In such operations as I have described the work of the Quartermaster-General is of an extremely onerous nature. Major-General Sir William Robertson has met what appeared to be almost insuperable difficulties with his characteristic energy, skill and determination; and it is largely owing to his exertions that the hardships and sufferings of the troops—inseparable from such operations—were not much greater. Major-General Sir Nevil Macready, the Adjutant-General, has also been confronted with most onerous and difficult tasks in connection with disciplinary arrangements and the preparation of casualty lists. He has been indefatigable in his exertions to meet the difficult situations which arose.

I have not yet been able to complete the list of officers whose names I desire to bring to your Lordship's notice for services rendered during the period under review; and, as I understand it is of importance that this despatch should no longer be delayed, I propose to forward this list, separately, as soon as I can.
