[This Gazette Issue covered two reports dated 17th September & 8th October] War Office, 18 October, 1914.
THE following despatch has been received by the Secretary of State for War from the Field-Marshal Commanding-in-Chief, British Forces in the Field :—
17th September, 1914
MY LORD, In continuation of my despatch of September 7th, I have the honour to report the further progress of the operations of the Forces under my command from August 28th.
On that evening the retirement of the Force was followed closely by two of the enemy's cavalry columns, moving south-east from St. Quentin.
The retreat in this part of the field was being covered by the 3rd and 5th Cavalry Brigades. South of the Somme, General Gough, with the 3rd Cavalry Brigade, threw back the Uhlans of the Guard with considerable loss.
General Chetwode, with the 5th Cavalry Brigade, encountered the eastern column near Cérizy, moving south. The Brigade attacked and routed the column, the leading German regiment suffering very severe casualties and being almost broken up.
The 7th French Army Corps was now in course of being railed up from the south to the east of Amiens. On the 29th it nearly completed its detrainment, and the French 6th Army got into position on my left, its right resting on Roye.
The 5th French Army was behind the line of the Oise between La Fère and Guise.
The pursuit of the enemy was very vigorous; some five or six German corps were on the Somme, facing the 5th Army on the Oise. At least two corps were advancing towards my front, and were crossing the Somme east and west of Ham. Three or four more German  corps were opposing the 6th French Army on my left.
This was the situation at 1 o'clock on the 29th, when I received a visit from General Joffre at my headquarters.
I strongly represented my position to the French Commander-in-Chief, who was most kind, cordial, and sympathetic, as he has always been. He told me that he had directed the 5th French Army on the Oise to move forward and attack the Germans on the Somme, with a view to checking pursuit. He also told me of the formation of the Sixth French Army on my left flank, composed of the 7th Army Corps, four Reserve Divisions and Sordêt's Corps of Cavalry.
I finally arranged with General Joffre to effect a further short retirement towards the line Compiègne-Soissons, promising him, however, to do my utmost to keep always within a day's march of him.
In pursuance of this arrangement the British Forces retired to a position a few miles north of the line Compiègne-Soissons on the 29th.
The right flank of the German Army was now reaching a point which appeared seriously to endanger my line of communications with Havre. I had already evacuated Amiens, into which place a German reserve division was reported to have moved.
Orders were given to change the base to St. Nazaire, and establish an advance base at Le Mans. This operation was well carried out by the Inspector-General of Communications.
In suite of a severe defeat inflicted upon the Guard 10th and Guard Reserve Corps of the German Army by the 1st and 3rd French Corps on the right of the 5th Army, it was not part of General Joffre's plan to pursue this advantage; and a general retirement on to the line of the Marne was ordered, to which the French Forces in the more eastern theatre were directed to conform.
A new Army (the 9th) had been formed from three corps in the south by General Joffre, and moved into the space between the right of the 5th and left of the 4th Armies.
Whilst closely adhering to his strategic conception to draw the enemy on at all points until a favourable situation was created from which to assume the offensive, General Joffre found it necessary to modify from day to day the methods by which he sought to attain this object, owing to the development of the enemy's plans and changes in the general situation.
In conformity with the movements of the French Forces, my retirement continued practically from day to day. Although we were not severely pressed by the enemy, rearguard actions took place continually. On the 1st September, when retiring from the thickly wooded country to the south of Compiegne, the 1st Cavalry Brigade was overtaken by some German cavalry. They momentarily lost a Horse Artillery battery, and several officers and men were killed and Wounded. With the help, however, of some detachments from the 3rd Corps operating on their left, they not only recovered their own guns but succeeded in capturing twelve of the enemy's.
Similarly, to the eastward, the 1st Corps, retiring south, also got into some very difficult forest country, and a somewhat severe rearguard action ensued at Villers-Cotterets, in which the 4th Guards Brigade suffered considerably. On September 3rd the British Forces were in position south of the Marne between Lagny and Signy-Signets. Up to this time I had been requested by General Joffre to defend the passages of the river as long as possible, and to blow up the bridges in my front. After I had made the necessary dispositions, and the destruction of the bridges had been effected, I was asked by the French Commander-in-Chief to continue my retirement to a point some 12 miles in rear of the position I then occupied, with a view to taking up a second position behind the Seine. This retirement was duly carried out. In the meantime the enemy had thrown bridges and crossed the Marne in considerable force, and wan threatening the Allies all along the line of the British Forces and the 5th and 9th French Armies. Consequently several small outpost actions took place.
On Saturday, September 5th, I met the French Commander-in-Chief at his request, and he informed me of his intention to take the offensive forthwith, as he considered conditions were very favourable to success.
General Joffre announced to me his intention of wheeling up the left flank of the 6th Army, pivoting on the Marne and directing it to move on the Ourcq; cross and attack the flank of the 1st German Army, which was then moving in a south-easterly direction east of that river.
He requested me to effect a change of front to my right - my left resting on the Marne and my right on the 5th Army - to fill the gap between that army and the 6th. I was then to advance against the enemy in my front and join in the general offensive movement.
These combined movements practically commenced on Sunday, September 6th, at sunrise; and on that day it may be said that a great battle opened on a front extending from Ermenonville, which was just in front of the left flank of the 6th French Army, through Lizy on the Marne, Mauperthuis, which was about the British centre, Courtecon, which was the left of the 5th French Army, to Esternay and Charleville, the left of the 9th Army under General Foch, and so along the front of the 9th, 4th, and 3rd French Armies to a point north of the fortress of Verdun.
This battle, in so far as the 6th French Army, the British Army, the 5th French army and the 9th French Army were concerned, may be said to have concluded on the evening of September 10th, by which time the Germans had been driven back to the line Soissons-Reims, with a loss of thousands of prisoners, many guns, and enormous masses of transport.
About the 3rd September the enemy appears to have changed his plans and to have determined to stop his advance South direct upon Paris; for on the 4th September air reconnaissances showed that his main columns were moving in a south-easterly direction generally east of a line drawn through Nanteuil and Lizy on the Ourcq.
On the 5th September several of these columns were observed to have crossed the Marne; whilst German troops, which were observed moving south-east up the left bank of the Ourcq on the 4th, were now reported to be halted and facing that river. Heads of the enemy's columns were seen crossing at Changis, La Ferté, Nogent, Château Thierry and Mezy.
Considerable German columns of all arms were seen to be converging on Montmirail, whilst before sunset large bivouacs of the enemy were located in the neighbourhood of Coulommiers, south of Rebais, La Ferté Gaucher and Dagny.
I should conceive it to have been about noon on the 6th September, after the British Forces had changed their front to the right and occupied the line Jouy-Le Chatel-Faremoutiers-Villeneuve Le Comte, and the advance of the 6th French Army north of the Marne towards the Ourcq became apparent, that the enemy realised the powerful threat that was being made against the flank of his columns moving south-east, and began the great retreat which opened the battle above referred to. On the evening of the 6th September, therefore, the fronts and positions of the opposing armies were roughly as follows :- ALLIES. 6th French Army.—Right on the Marne at Meux, left towards Betz.
British Forces.—On the line Dagny-Coulommiers-Maison.
5th French Army.—At Courtagon, right on Esternay.
Conneau's Cavalry Corps.—Between the right of the British and the left of the French 5th Army. GERMANS. 4th Reserve and 2nd Corps.—East of the Ourcq and facing that river.
9th Cavalry Division.—West of Crecy.
2nd Cavalry Division..—North of Coulommiers
3rd and 7th Corps.—South-west of Montmirail. All these troops constituted the 1st German Army, which was directed against the French 6th Army on the Ourcq, and the British Forces, and the left of the 5th French Army south of the Marne.
The 2nd German Army (IX., X., X.R. and Guard) was moving against the centre and right of the 5th French Army and the 9th French Army. On the 7th September both the 5th and 6th French Armies were heavily engaged on our flank. The 2nd and 4th Reserve German Corps on the Ourcq vigorously opposed the .advance of the French towards that river, but did not prevent the 6th Army from gaining some headway, the Germans themselves suffering serious losses. The French 5th Army threw the enemy back to the line of the Petit Morin river after inflicting severe losses upon them, especially about Montceaux, which was carried at the point of the bayonet.
The enemy retreated before our advance, covered by his 2nd and 9th and Guard Cavalry Divisions, which suffered severely.
Our Cavalry acted with great vigour, especially General De Lisle's Brigade with the 9th Lancers and 18th Hussars. On the 8th September the enemy continued his retreat northward, and our Army was successfully engaged during the day with strong rearguards of all arms on the Petit Morin River, thereby materially assisting the progress of the French Armies on our right and left, against whom the enemy was making his greatest efforts. On both sides the enemy was thrown back with very heavy loss. The First Army Corps encountered stubborn resistance at. La Trétoire (north of Rebais). The enemy occupied a strong position with infantry and guns on the northern bank of the Petit Morin River; they were dislodged with considerable loss. Several machine guns and many prisoners were captured, and upwards of two hundred German dead were left on the ground.
The forcing of the Petit Morin at this point was much assisted by the Cavalry and the 1st Division, which crossed higher up the stream.
Later in the day a counter attack by the enemy was well repulsed by the First Army Corps, a great many prisoners and some guns again falling into our hands.
On this day (8th September) the Second Army Corps encountered considerable opposition, but drove back the enemy at all points with great loss, making considerable captures.
The Third Army Corps also drove back considerable bodies of the enemy's infantry and made some captures. This map (right), from the Daily Express issue of 11th September 1914 gives an idea of the disposition of forces at this volatile early stage of Britain's part in World War 1 alongside the French forces. On the 9th September the First and Second Army Corps forced the passage of the Marne and advanced some miles to the north of it. The Third Corps encountered considerable opposition, as the bridge at La Ferté was destroyed and the enemy held the town on the opposite bank in some strength, and thence persistently obstructed the construction of a bridge; so the passage was not effected until after nightfall.
During the day's pursuit the enemy suffered heavy loss in killed and wounded, some hundreds of prisoners fell into our hands and a battery of eight machine guns was captured by the 2nd Division.
On this day the 6th French Army was heavily engaged west of the River Ourcq. The enemy had largely increased his force opposing them; and very heavy fighting ensued, in which the French were successful throughout.
The left of the 5th French Army reached the neighbourhood of Château Thierry after the most severe fighting, having driven the enemy completely north of the river with great loss.
The fighting of this Army in the neighbourhood of Montmirail was very severe.
The advance was resumed at daybreak on the 10th up to the line of the Ourcq, opposed by strong rearguards of all arms. The 1st and 2nd Corps, assisted by the Cavalry Division on the right, the 3rd and 5th Cavalry Brigades on the left, drove the enemy northwards. Thirteen guns, seven machine guns, about 2,000 prisoners, and quantities of transport fell into our hands. The enemy left many dead on the field. On this day the French 5th and 6th Armies had little opposition.
As the 1st and 2nd German Armies were now in full retreat, this evening marks the end of the battle which practically commenced on the morning of the 6th instant; and it is at this point in the operations that I am concluding the present despatch.
Although I deeply regret to have had to report heavy losses in killed and wounded throughout these operations, I do not think they have been excessive in view of the magnitude of the great fight, the outlines of which I have only been able very briefly to describe, and the demoralisation and loss in killed and wounded which are known to have been caused to the enemy by the vigour and severity of the pursuit:
In concluding this despatch I must call your Lordship's special attention to the fact that from Sunday, August 23rd, up to the present date (September 17th), from Mons back almost to the Seine, and from the Seine to the Aisne, the Army under my command has been ceaselessly engaged without one single day's halt or rest of any kind.
Since the date to which in this despatch I have limited my report of the operations, a great battle on the Aisne has been proceeding. A full report of this battle will be made in an early further despatch.
It will, however, be of interest to say here that, in spite of a very determined resistance on the part of the enemy, who is holding in strength and great tenacity a position peculiarly favourable to defence, the battle which commenced on the evening of the 12th instant has, so far, forced the enemy back from his first position, secured the passage of the river, and inflicted great loss upon him, including the capture of over 2,000 prisoners and several guns. I have the honour to be,
Your Lordship's most obedient Servant,
(Signed) J. D. P. FRENCH, Field-Marshal,
The British Forces in the Field.
