The already-mentioned directions from Versailles had been communicated in advance by the Chief of the General Staff, and in accordance with them General Manteuffel now decided on leaving only the Ist Corps on the Lower Seine, and returning with the VIIIth to the Somme, where the French in Arras were now becoming active. Besides making this evident by various small encounters, on December 9th they had attacked a company detailed to protect the reconstruction of the railway at Ham, surprising it at night, and taking most of the men prisoners; while on the 11th several French battalions advanced as far as La Fere. To check their further progress, the Army of the Meuse had meantime sent detachments to Soissons and Compiegne. General Count von der Groeben[56] (commanding 3rd Cavalry Division) took up a position at Roye with part of the garrison of Amiens, and on the 16th met the 15th Division at Montdidier, which immediately moved up to the Somme. Only the citadel of Amiens now remained in German occupation; but General von Manteuffel, who had not approved of the evacuation of the city, ordered its immediate reoccupation. The inhabitants had, however, remained peaceable, and on the 20th the 16th Division, which had given up the attack on Havre, arrived by way of Dieppe. A reconnoissance fight near Querrieux made it certain that great numbers of French were drawn up on the Hallue, and General von Manteuffel now drew in the whole (VIIIth) Corps on Amiens. Reinforcements were shortly to be expected, for the 3rd Reserve Division was on the march, and had already reached St. Quentin. The Ist Corps was also ordered to send a brigade from Rouen to Amiens by railway, and the Commanding General determined to take the offensive at once with 22,600 men, all his available force at the moment. General Faidherbe had assembled two Corps, the XXIInd and XXIIIrd. His advance on Ham and La Fere, intended to divert the Prussians from attacking Havre, had succeeded. He next turned toward Amiens, advanced to within nine miles of the city, and now stood, with 43,000 men and eighty-two guns, fronting to the west behind the Hallue. Two Divisions held the left bank of this stream for about seven miles, from its confluence at Daours up to Contay, two standing further back, at Corbie and Fravillers. The Somme secured the left flank. On December 23rd General von Manteuffel, with the VIIIth Corps, advanced on the road to Albert. The 3rd Brigade of the Ist Corps formed his reserve. His design was to keep the French engaged by the 15th Division on their front and left wing, and with the 16th Division to outflank their right. The unexpected extension of the French right wing prevented this, and it became a frontal battle along the whole line. The greater height of the eastern bank afforded the French a commanding artillery position, and the villages lying at the foot had in every instance to be stormed.
