To cover its threatened line of retreat, the Brigade Michelet once more advanced from Fayet, and the Brigade Pauly also marched from Gricourt upon Moulin Coutte. This position, which had in the meantime been strengthened by artillery, was, however, obstinately held by the 44th Regiment, and when the Grenadier companies poured in leftward towards the Roman road, the enemy's attack was here also repulsed. Meanwhile the 29th Brigade, followed by the 30th, had already advanced in the direction of St. Quentin, the 33rd Regiment on its right and the 65th Regiment on the left. The latter regiment now took complete possession of the larger copse, and forty-eight guns were brought up on both sides of the road from Savy. The further advance of the infantry was effected in column of companies and on an extended line, because of the heavy shell fire of the French. The Brigades of Lagrange and Isnard did not await the shock, but at four o'clock retired on St. Quentin with the loss of one gun. Their artillery once more took up a position at Rocourt, but at five o'clock had to abandon it abruptly, and the French now confined themselves to the defence of the barricaded accesses into the St. Martin suburb of St. Quentin. Six Prussian batteries were brought up against these, and the 29th Brigade for some time maintained a stationary fire fight on the strongly held buildings and gardens; but presently several companies from Rocourt established themselves in the suburb, in which street-fighting was still continued, even after Lieutenant-Colonel von Huellessem had succeeded in crossing the canal bridge and entering the town itself. By four o'clock, General Faidherbe had already the conviction that the XXIIIrd Corps would probably be unable to hold its ground. In this event his choice was limited to the alternative of a night retreat, or of being shut up in St. Quentin. He had not yet formed a decision, when he met in the town General Lecointe, who reported that he had abandoned the defence of the left bank of the Somme. Thanks to the resistance still maintained by the XXIIIrd Corps on the north, the XXIInd was enabled to retire unmolested on Le Cateau. The Commanding General now ordered General Paulze d'Ivoy to retire on that place, but the latter only received the order at six in the evening, when the brigades of the right wing--Pauly's and Michelet's--had already started of their own accord for Cambrai. The more obstinately the two remaining brigades now defended the suburb of St. Martin, the more ominous for them must prove the result of the action. Attacked in rear by the battalions of Colonel von Boecking, the greater portion were made prisoners. The 41st Regiment alone took prisoners 54 officers and 2260 men, besides capturing 4 guns. General Faidherbe himself only escaped the same fate by the help of the inhabitants. The action ended at half-past six in the evening, and the troops passed the night in the town and in the captured villages.
