General Chetwode routs German attack.
General Chetwode, with the Fifth Cavalry Brigade, encountered the eastern column near Cerizy, moving south. The brigade attacked and routed the column, the leading German regiment suffering very severe casualties and being almost broken up.
The Seventh 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 Sixth Army got into position on my left, its right resting on Roye.
The Fifth French Army was behind the line of the Oise, between La Fère and Guise.
Vigorous pursuit of retreating German forces.
The pursuit of the enemy was very vigorous; some five or six German corps were on the Somme, facing the Fifth Army on the Oise. At least two corps were advancing toward my front, and were crossing the Somme east and west of Ham. Three or four more German corps were opposing the Sixth 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 Fifth 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 Seventh Army Corps, four reserve divisions, and Sordêt's corps of cavalry.
Short retirement towards Compiègne-Soissons.
I finally arranged with General Joffre to effect a further short retirement toward 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.
Right flank of German army in dangerous line of connection.
The right flank of the Germany 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.
Retirement to the Marne ordered.
In spite of a severe defeat inflicted upon the Guard Tenth and Guard Reserve Corps of the German Army by the First and Third French Corps on the right of the Fifth Army, it was not part of General Joffre's plan to pursue this advantage; and a general retirement 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 Ninth) had been formed from three corps in the south by General Joffre, and moved into the space between the right of the Fifth and left of the Fourth Armies.
While closely adhering to his strategic conception to draw the enemy on at all points until a favorable 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.
Attack on British First Cavalry Brigade.
On the 1st September, when retiring from the thickly wooded country to the south of Compiègne, the First 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 Third 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 First Corps, retiring south, also got into some very difficult forest country, and a somewhat severe rearguard action ensued at Villers-Cotterets, in which the Fourth Guards Brigade suffered considerably.
British forces in position south of the Marne.
On September 3 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 twelve 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 was threatening the Allies all along the line of the British forces and the Fifth and Ninth French Armies. Consequently several small outpost actions took place.
On Saturday, September 5, 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 very favorable to success.
General Joffre announces intention to take offensive.
General Joffre announced to me his intention of wheeling up the left flank of the Sixth Army, pivoting on the Marne and directing it to move on the Ourcq; cross and attack the flank of the First German Army, which was then moving in a southeasterly 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 Fifth Army—to fill the gap between that army and the Sixth. I was then to advance against the enemy in my front and join in the general offensive movement.
Battle begins Sunday, September 6.
These combined movements practically commenced on Sunday, September 6, 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 Sixth French Army, through Lizy on the Marne, Mauperthuis, which was about the British centre, Courtecon, which was on the left of the Fifth French Army, to Esternay and Charleville, the left of the Ninth Army under General Foch, and so along the front of the Ninth, Fourth and Third French Armies to a point north of the fortress of Verdun.
Battle concluded September 10. Germans driven to the line Soissons-Rheims.
This battle, in so far as the Sixth French Army, the British Army, the Fifth French Army, and the Ninth French Army were concerned, may be said to have concluded on the evening of September 10, by which time the Germans had been driven back to the line Soissons-Rheims, with a loss of thousands of prisoners, many guns, and enormous masses of transport.
About September 3 the enemy appears to have changed his plans and to have determined to stop his advance south direct upon Paris, for on September 4 air reconnoissances showed that his main columns were moving in a southeasterly direction generally east of a line drawn through Nanteuil and Lizy on the Ourcq.
On September 5 several of these columns were observed to have crossed the Marne, while German troops, which were observed moving southeast up the left flank 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.
German columns converging on Montmirail.
Considerable German columns of all arms were seen to be converging on Montmirail, while before sunset large bivouacs of the enemy were located in the neighborhood of Coulommiers, south of Rebais, La Ferté-Gaucher, and Dagny.
I should conceive it to have been about noon on September 6, 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 Sixth French Army north of the Marne toward the Ourcq became apparent, that the enemy
