The fine strategic movement of the 42nd (_see p. 14_) is easy to follow. The Division gained the plain from the plateau north of Sézanne which we traversed yesterday. The infantry descended the slopes of Broyes and Allemant. The military wagons followed the N. 34 and the railway which skirts this road. The batteries stopped on the way at Broyes, in order to take part in the bombardment of Mondement Castle. The division formed up between Linthes, Linthelles and Pleurs, and it was from this point that it began its attack. The tourist may picture to himself these red and blue columns marching eastwards under a violent artillery fire, and causing the German troops, bewildered by the arrival of these unexpected French reinforcements, to disappear again behind the ridge. The villages of Péas (panorama II) and Saint-Loup (panorama III) served as shelters for the reserves of the Ninth Corps. Much-tried companies withdrew there to reform. It was from Saint-Loup that the 77th Infantry Regiment started forth to take Mondement. Leaving their dinner which was warming, these gallant fellows stormed the slopes of Allemant and of Broyes in order to take in this action the heroic part explained on p. 117. _Rejoin_ G. C. 39. _The long dike of the marshes of Saint-Gond becomes visible almost immediately._ From this distance nothing indicates the marshes, whose reeds are lost to view among the crops; one can only distinguish the line of the Petit Morin, marked by poplar trees, which traverses the depression from one end to the other. After passing a small group of houses, take, at the cross-roads, the road on the left descending towards the marshes. We can perceive Mont-Août first in front, then to the right. This solitary little hill played an important part in the battle. There, until September 9, the 17th Division resisted all attacks from the north and from the east. _Follow_ G. C. 39, _and arriving at =Broussy-le-Grand= (16 km.), pass through it._ Held first by the Moroccan Division, Broussy was carried by the Germans after a fierce struggle. The French troops were thrown back on the slopes of Allemant which we have just descended. There are still many ruined houses in Broussy. _The road now turns towards =Bannes= (19 km.)._ Across the plain which stretches south and east of Bannes, the 17th and 52nd Divisions fought desperate engagements to prevent the Germans from breaking through the marshes. On the 8th, the French front, which followed the boundary of the marshes from east to west, was pushed back with violence. The left remained in the neighbourhood of Bannes, but the centre drew back to Mont-Août, and the right to the south of this hill. On the 9th, Mont-Août fell in its turn. Between Bannes and Mont-Août, in a trench, numerous letters and telegrams and a box bearing the address of Prince Eitel, son of Wilheim II., were found. Many new roofs are to be seen in Bannes, a proof of the violence of the bombardment.
