In connection with the large number of stragglers, who were afterwards gathered together and showed {78} by their conduct that they had no want of stomach for the fight, it is to be remembered that the men had been accustomed to the narrow routine of trench operations, that most of them had no idea of open warfare, and that when they found themselves amidst swift evolutions over difficult country, carried on frequently in darkness, it was very natural that they should lose their units and join the throng who wandered down the main roads and were eventually rounded up and formed into formations at the river crossings or other places where they could be headed off. Among the casualties were many senior officers, including General Bailey of the 142nd Brigade. {79} CHAPTER IV THE SECOND BATTLE OF THE SOMME Attack upon the Fifth Army. March 21. The Fifth Army front--The story of a Redoubt--Attack upon Congreve's Seventh Corps--Upon Watts' Nineteenth Corps--Upon Maxse's Eighteenth Corps--Upon Butler's Third Corps--Terrific pressure--Beginning of the Retreat--Losses of Guns. [Sidenote: Fifth Army. March 21.] In dealing with the German attack upon the Fifth Army, the first point which should be emphasised is, that heavy as the fighting was in the north, still it was this southern advance which was the main one. The official account of the disposition of the German forces brings this fact out very clearly. From the Sensée River to the Bapaume-Cambrai Road they are stated to have had nine divisions in line and eight in close reserve, covering a front of nine miles. In the eight miles from Cambrai Road to La Vacquerie they had four divisions. In the southern area from La Vacquerie down to La Fère they had twenty-three divisions in the line and seventeen in reserve, covering a front of over forty miles. This front was defended by eleven British divisions, with three divisions of infantry and three of cavalry in reserve. So far as infantry was concerned the odds were 40 to 14, while the German guns numbered about 3500 to 1300 on the British {80} line. These odds were serious enough if directed equally along the whole area, but when thrown in on special sectors they became more crushing. To add to the total picture of German strength, it should be added that twenty-five fresh divisions were thrown into the fight during the first week, nine upon the Scarpe front, three between the Ancre and the Somme, seven between the Somme and Montdidier, and six between Montdidier and the Oise. Against these have to be set British reinforcements, and the influx of French from the south. It was only on the first five days of battle that the odds were so overpoweringly with the Germans.
