On the left of the attack English and Irish troops forced the passage of the Scheldt Canal at Gouy and Le Catelet and captured both villages. At the farthest point of this advance the British penetrated German positions to a depth of about five miles. Over 5,000 prisoners were taken by the British during the drive.
In Flanders the Germans were in retreat on the twenty-mile front between Armentières and Lens, which the British now occupied. Between these strongholds the British had advanced their line three miles eastward through Avion, Vendin, Wieres, and Herlies.
St. Quentin was completely cleared of German troops by October 2, 1918. Not one of its original 56,000 inhabitants remained. All were carried away by the Germans. As it was believed the enemy had mined the town with time fuses the French did not occupy the town, but remained outside waiting for developments.
From St. Quentin to the Argonne the French armies continued to gain ground all along the line. They were closing the only avenue of escape for the Germans on the west side of the Argonne Forest, and clearing the region north and west of Rheims.
General Gouraud on the eastern side of the line by the occupation of the important railway town of Challerange now controlled the western exit from the Grand Pré Gap through the forest. Southeast of Orfeuil the French held a wooded area, their guns dominating the only railway which was available to the Germans north of that position. The French also enlarged their gains north of Somme-Py in the Champagne, capturing Mont Blanc with the Americans and the Medeah Farm.
Around Rheims the Germans had been forced back so far that the city must soon be freed from the menace of bombardment. Cormicy, northwest of the city, was captured by the French and Loivre to the north, while the Aisne Canal was reached between Concevreux and La Neuvillette.
Debeney's indomitable troops north and east of St. Quentin continued to drive forward. He broke the Hindenburg line from Le Tronquoy to Lesdins and gained a hold on the railway east of St. Quentin. Progress was also made at Neuville St. Armand and Itancourt. Continuing their pressure on the Germans seeking to repair the gap torn in the Hindenburg defenses northeast of St. Quentin, British troops on October 4-5, 1918, pushed on toward Fresnoy-le-Grand in the face of determined and powerful enemy counterattacks.
The Germans continued to retreat on the Lens-Armentières front. The British lines were advanced over two miles to Erquinghem and Wavrin west and southwest of Lille.
In the Champagne the entire enemy front was crumbling before the hammer blows of the French army under Berthelot and the Franco-American legions under Gouraud. North of Rheims the capture of Fort Brimont and strong mountain positions to the east gave the French enormous advantage over the enemy, of which they were not slow to avail themselves. The entire massif of Moronvilliers was conquered; by the afternoon of October 5, 1918, the French had reached Bethenville, three miles to the north. In the course of the advance the Germans were forced to evacuate many positions which they had held since 1914.
Threatened by the British thrust toward Lille the enemy began the evacuation of the city. Farther south, in the crucial area north of St. Quentin, British forces again broke through the Hindenburg system of defenses. They crossed the Scheldt Canal on the eight-mile front between Crèvecœur and Le Catelet and won a section of the famous line on the plateau of La Terrière in this sector, the Germans hurriedly retiring from the high ground east of the canal.
