On the 10th of January, General von Barnekow entered the fortress, which was found amply provided with arms, ammunition and provisions. The garrison were made prisoners.
On the 7th of January, his Majesty the King had assigned General von Manteuffel to another section of the theatre of war, and had given the supreme command of the Ist Army to General von Goeben.
Freed from concern as to Péronne, that General's only duty thenceforward was to insure the protection of the investment of Paris. For this purpose the Somme, whose passages were all in the hands of the Germans, formed a natural bulwark, behind which the attack even of a greatly superior enemy could be awaited. And some reinforcements now arrived for the VIIIth Army Corps. The peaceful condition of the Lower Seine allowed of two infantry regiments and two batteries being sent from thence to Amiens. By instructions from the supreme Head-quarter an infantry brigade of the Meuse Army was held in readiness, which in case of need was to be sent up by rail to reinforce the Ist Army.
It was still uncertain whither the enemy would direct his stroke. General von Goeben, therefore, spread his forces behind the Somme on a prolonged extension of some forty-five miles, still holding fast the points gained in front of the river, to meet the contingency of his having to renew the offensive. In the middle of the month, the detachments of the Ist Corps under the command of General Count von der Groeben occupied Amiens, Corbie, and the line of the Hallue as a flank position. The 15th Division, holding Bray firmly, took up quarters south of that village. Next to it, on the left of Péronne, was the 3rd Reserve Division, right of it were the 16th Division and the 3rd Reserve Cavalry Brigade, holding Roisel and Vermand to the front. The 12th Cavalry Division was at St. Quentin.
The French army had already begun to advance on the Cambrai high-road, and its XXIInd Corps had pushed back the 3rd Cavalry Division first out of Bapaume and then out of Albert behind the Hallue. The XXIIIrd followed by the same road, and their objective really appears to have been Amiens. But a reconnaissance had exposed the difficulty of attacking in that direction, besides which a telegram from the War Minister announced that the Army of Paris within the next few days was to make a last supreme effort to burst the bonds of the investment, and the Army of the North was enjoined to divert, as far as possible, the enemy's forces from the capital, and draw them on itself.
In accordance with these orders General Faidherbe decided to advance without delay on St. Quentin, whither the Brigade Isnard was already marching from Cambrai. An attack on their right wing, consisting for the time solely of cavalry, directly threatened the communications of the Germans, while the vicinity of the northern forts afforded the French army shelter and also greater liberty of action.
But General von Goeben had foreseen such a leftward movement of the enemy, and concentrated all his forces to meet it.
The convalescents who were fit for service joined the ranks. Only weak detachments were left at Amiens, and because of the approach of the XIIIth Corps from the Sarthe to the Lower Seine, it was now safe to transfer the 3rd Grenadier Regiment and a heavy battery from thence to the Somme.
The departure of the French from Albert and the march of their Corps on Combles and Sailly Saillisel were soon reported by the cavalry in observation. The newly-formed Brigade Pauly occupied Bapaume, and the Brigade Isnard entered St. Quentin, whence General zur Lippe (commanding the 12th (Saxon) Cavalry Division detailed from the Army of the Meuse) retired on Ham in accordance with orders. General von Goeben now moved eastward, using the roads on both banks of the Somme so that he might the sooner reach the enemy.
January 17th.—The 12th Cavalry Brigade moved further to the right on La Fère, the 16th Division to Ham. The 3rd Reserve Division and the Guard Cavalry Brigade arrived at Nesle; the 15th Division and the Corps Artillery, at Villers Carbonnel. An Army-Reserve had been formed of the troops last brought up from Rouen, and it followed to Harbonnières. On the northern bank, the detachment under Count von der Groeben moved to the vicinity of Péronne.
