Battle of St. Quentin Canal

Overview

The Battle of St Quentin Canal was a pivotal battle of World War I that began on 29 September 1918 and involved British, Australian and American forces operating as part of the British Fourth Army under the overall command of General Sir Henry Rawlinson. Further north, part of the British Third Army also supported the attack. South of the Fourth Army's 19 km (12 mi) front, the French First Army launched a coordinated attack on a 9.5 km (6 mi) front. The objective was to break through one of the most heavily defended stretches of the German Siegfriedstellung, which in this sector used the St Quentin Canal as part of its defences. The assault achieved its objectives, resulting in the first full breach of the Hindenburg Line, in the face of heavy German resistance. In concert with other attacks of the Grand Offensive along the length of the line, Allied success convinced the German high command that there was little hope of an ultimate German victory.

Significance

The Battle of St Quentin Canal, beginning 29 September 1918, produced the first full breach of the Hindenburg Line—the heavily fortified Siegfriedstellung that German planners regarded as the backbone of their defensive position on the Western Front. The assault was conducted by British, Australian, and American forces under the Fourth Army, with the British Third Army supporting to the north and the French First Army attacking on a 9.5 km front to the south. Breaking through a sector where the St Quentin Canal itself formed part of the German defenses, the operation inflicted roughly 36,000 German casualties against approximately 8,800 Allied losses. Coming alongside concurrent Allied attacks across the length of the line during the Grand Offensive, the result persuaded the German high command that ultimate victory was no longer attainable, accelerating the collapse of German strategic confidence in the war's final weeks.
