On August 10, an offensive by Humbert's Army began to clear the whole region. At 4.20 a.m., the 129th, 165th, 6th, 121st, 74th, 123rd, 67th, 38th and 15th Divs. attacked from Courcelles to Antheuil and from Antheuil to the Oise. At 7 a.m. the first objectives were reached. Ressons, through which ran the enemy's main line (the "Gothenstellung") was passed, whilst Marquéglise, the Château of Séchelles, Chevincourt and Bourmont were captured. The whole of a Regimental Staff was captured at the Château of Séchelles. At Ressons the tanks threw the Germans into confusion. On the 11th, Vignemont, Margny, Le Plessier, Hill 179, Mareuil-la-Motte, Bellinglise Château and Élincourt were captured. The French advanced in the direction of Gury and St. Claude Farm, which formed the key of the "Gothenstellung" position, and by evening had reached the western outskirts of Gury, a point south of La Berlière and Hill 143, and approached St. Claude Farm, Hill 166, Samson, Cense Farm and the quarries of Montigny and Antoval. On the 12th, they captured and progressed beyond Gury and St. Claude Farm, and took Écouvillon and Loges Wood, the latter being, however, lost again in the afternoon. On the 13th, they advanced along the plateau, gained a footing in Plessis Park, reached the eastern outskirts of Belval, and attained a point 800 yards north-east of Gury. Entering Ribécourt on the 14th, they re-occupied the Attiche and Monolithe Farms on the 15th, as well as the quarries situated 2 kms. north-west of Ribécourt. On the 17th, the Germans delivered several powerful attacks near Monolithe and Attiche Farms, but failed to drive back the French, who strongly held the newly conquered ground. [Illustration: ST. CLAUDE FARM.] _From St. Claude Farm, return to Élincourt. Near the church, take Rue de l'Escalier_ (G.C. 142) _and the road on the left of the Calvary. 1 km. further on, near a block of houses, follow the right-hand road, passing through_ =Marest-sur-Matz=. _The road skirts the_ CHATEAU OF RIMBERLIEU, _opposite which is_ a tower--all that remains of an old fortified castle. =Villers-sur-Coudun= _is next reached_, whose church is situated on the left, near the end of the village. The end of the chancel is 12th-13th century, the façade and vaulting 15th-16th century, the remainder modern. _Continue along the road to_ =Coudun=, formerly the Head-Quarters of the Training Camp built in 1698 for the Duke of Burgundy, grandson of Louis XIV. The king, accompanied by James II of England, paid a visit to this camp in August, to attend the military manœuvres. The camp, under the command of Marshal de Boufflers, extended along the plateau which dominates the right bank of the Oise from Lachelle to Margny and from Baugy to the Château of Bienville. 50 battalions of Infantry, 52 squadrons of Cavalry and 40 guns were stationed there.
