Detail showing the British sector of the Western Front from a map of the Allied offensives of 1918, from July 18 and the Second Battle of the Marne to the Armistice on November 11. From The Memoirs of Marshall Foch by Marshall Foch. The 1st and other armies to the south are French.
"On the first day of their attack in this region, September 29, the British Fourth Army advanced five kilometers. After two more days of heavy fighting, the British pushed their way through German defenses. Though the density of enemy divisions between Arras and Soissons was almost double that between Soissons and Verdun, the British made rapid progress south of Arras while the French and Americans made only small progress between Soissons and Verdun. . . .To the south of St.-Quentin, Debeney's First Army, which had the mission of supporting the British Fourth Army's operation, did nothing more on the twenty-ninth than provide assistance with artillery and launch a small attack on an enemy strong point ten kilometers south of St.-Quentin."
The British offensive on September 29, 1918 was the last of Allied Commander-in Chief Ferdinand Foch's four offensives on four consecutive days at the end of the month, preceded by the Franco-American Meuse-Argonne Offensive of the 26th, the British offensive by the First and Third Armies towards Cambrai on the 27th, and the attack by the Flanders Group of Armies — Belgian, French, and British — under the command of Albert, King of the Belgians on the 28th.
