# Battle of the Canal du Nord

vteCanal du Nord :
Legend :
The Battle of Canal du Nord was part of the Hundred Days Offensive of the First World War by the Allies against German positions on the Western Front. The battle took place in the Nord-Pas-de-Calais region of France, along an incomplete portion of the Canal du Nord and on the outskirts of Cambrai between 27 September and 1 October 1918. To prevent the Germans from sending reinforcements against one attack, the assault along the Canal du Nord was part of a sequence of Allied attacks at along the Western Front. The attack began the day after the Meuse-Argonne Offensive commenced, a day before an offensive in Belgian Flanders and two days before the Battle of St. Quentin Canal.
The attack took place along the boundary between the British First Army and Third Army, which were to continue the advance started with the Battle of the Drocourt-Quéant Line, Battle of Havrincourt and Battle of Epehy. The First Army was to lead the crossing of the Canal du Nord and secure the northern flank of the British Third Army as both armies advanced towards Cambrai. The Third Army was also to capture the Escaut (Scheldt) Canal, to support the Fourth Army during the Battle of St. Quentin Canal.

## Background

Construction of the Canal du Nord began in 1913 to link the Oise River to the Dunkirk–Scheldt Canal. When the First World War began, work stopped with the canal in varying stages of completion. During their retreat, the Germans made the area along the canal north of Sains-lès-Marquion virtually impassable by destroying bridges and flooding the already swampy ground surrounding the canal. The only passable ground was to the south, where a small 4,000 yd (2.3 mi; 3.7 km) section of the canal between Sains-lès-Marquion and Mœuvres remained largely dry, on account of its incomplete state. Even in a partially excavated state, the dry section of the canal was still a serious obstacle. The canal was approximately 40 yd (37 m) wide, with a western bank that was between 10 and 15 ft (3.0 and 4.6 m) high and an eastern bank about 5 ft (1.5 m) high. The British First Army (General Henry Horne) was forced to stop its offensive until a route was secured across the canal.
The British assault on the Drocourt-Quéant Line on 2 September 1918 resulted in the Germans being overrun along a 7,000 yd (4.0 mi; 6.4 km) front. Several formations in the German forward line quickly yielded to the British advance but then the British met more resolute opposition from regiments of the German 1st Guards Reserve Division, 2nd Guards Reserve Division and the 3rd Reserve Division. To gain observation of all bridges over the Sensée River and the Canal du Nord, the British attack was supposed to continue the following day but the Germans forestalled the British by withdrawing along a wide front.
Oberste Heeresleitung (OHL, the German army high command) had ordered the 17th Army to retreat behind the Sensée River and the Canal du Nord on the night of 2 September and the 2nd Army to withdraw to the Hindenburg Line the following night. Further to the south, the 18th and 9th Armies were to follow in succession, resulting in the abandonment of the salient gained during the Spring Offensive by 9 September. In the north the 4th and 6th Armies retreated between Lens and Ypres, abandoning the Lys salient and the gains made during the Battle of the Lys.
British air patrols on the morning of 3 September reported seeing no Germans between the Dury Ridge and the Canal du Nord. The Third Army was able to occupy the towns of Quéant and Pronville unopposed and saw that the Germans were withdrawing on a wide front. As the British advanced to the new German front line they reported that the east bank of the Canal du Nord was strongly held and that the canal crossings had been destroyed except at Palluel, where the Germans held a bridgehead on the western side of the canal.

## Tactical plan and preparations

On 3 September Supreme Commander of the Allied Armies Généralissime Ferdinand Foch outlined the future course of the Allied offensive campaign along the Western Front. To avoid the risk of having extensive German reserves massed against a single Allied attack, Foch devised a plan for a general offensive between Verdun and the Belgian coast. The plan called for Allied attacks at four separate points in the German line, to be launched on four successive days. Army Group Flanders under King Albert I of Belgium would conduct the most northern operation and attack German positions in Flanders and move towards Ghent and Bruges. The British First and Third Armies would attack and cross the Canal du Nord, move across the northern extension of the Hindenburg Line and capture the city of Cambrai, a crucial German communications and supply centre. The British Fourth Army and French First Army would attack the Germans along the Saint-Quentin Canal in an effort to breach the Hindenburg Line between Holnon and Vendhuile. To the south, the First United States Army and French Fourth Army would mount the Meuse-Argonne Offensive between Reims and Verdun, moving along the Meuse River and through the Argonne Forest.
The Canal du Nord defensive system was the Germans' last major prepared defensive position opposite the British First Army. It was a significant obstacle as the Germans had taken measures to incorporate the unfinished canal into their defensive system. Beyond the damage done to make crossing the canal as difficult as possible, north of Mœuvres a lesser arm of the Hindenburg Support Line, the Canal du Nord Line, ran directly behind the east side of the canal. The greater arm of the Hindenburg Support Line crossed the canal at Mœuvres and thus remained well established on the eastern side of the canal south of Mœuvres. This was supplemented by the Marquion-Cantaing Line which ran along a north–south axis one mile east of the canal and the Marcoing Line located just west of Cambrai. The attack on the Canal du Nord was to begin on 27 September 1918, a day after the Meuse-Argonne Offensive, one day before the offensive in Flanders and two days before the Battle of St. Quentin Canal.
The British First Army was operating in a framework whereby its main task was to secure the northern flank of the British Third Army. The British Third Army was tasked with securing the Escaut (Scheldt) Canal so as to be in a position to support the British Fourth Army during the Battle of St. Quentin Canal. On the British First Army front, the Canadian Corps would lead the attack under the direction of Arthur Currie, crossing the largely dry canal on a front of only 2,700 yards (2,500 m) between Sains-lès-Marquion and Mœuvres. Once over the canal the corps was to capture the Marquion Line, the villages of Marquion and Bourlon, Bourlon Woods and lastly secure a general line running from Fontaine-Notre-Dame to Sauchy-Lestrée. Currie separated the Canadian Corps' objectives into two phases; the first to take Canal du Nord and Bourlon Wood, the second taking the bridges at Canal de l'Escaut and "high ground near Cambrai".
In an attempt to make the Germans second guess or question the location of the main assault, XXII Corps was instructed to engage German positions along the Canal du Nord between Sauchy-Lestrée and Palluel. Likewise, VII Corps and the remainder of XXII Corps were instructed to carry out minor attacks north of the Scarpe River to prevent the Germans from moving units from that area to the location of the main attack. If the Canadian Corps was successful in its advance the intention was to immediately and quickly exploit the territorial gain with the support of the British Third Army's XVII, VI and IV Corps.

## Battle

Over the next week, Currie and Byng prepared for the engagement. Two divisions were sent south, to cross the canal at a weaker point, while Canadian combat engineers worked to construct the wooden bridges for the assault. The bridges were necessary because where the Canadians were crossing the Canal du Nord was flooded and the only locations that had no flooding were being guarded by the German defences. Currie had the Canadians cross mostly through a flooded area but included a "narrow strip" of the unflooded area to hit the German flank.
At 5:20 on the morning of 27 September, all four divisions attacked under total darkness, taking the German defenders of the 1st Prussian Guards Reserve Division and the 3rd German Naval Division by absolute surprise. By mid-morning, all defenders had retreated or been captured. Stiffening resistance east of the canal proved that only a surprise attack had the possibility of ending in victory.
The Canadian Corps had the important objective of capturing Bourlon Woods, the German army used the high ground of the woods for their guns. The objectives of the Canadian Corps were reached by the end of the day, including the Red, Green and Blue lines.
The British attack was supported to the south by the French First Army during the Battle of Saint Quentin (French: Bataille de Saint-Quentin). (However, this attack was a secondary attack, and did not start until after the Canadian Corps had penetrated the German defences along the canal.)
Because of Canal du Nord's capture, the final road to Cambrai was open.

## Aftermath

The battle penetrated a majority of the defenses of the Hindenburg Line and allowed the next attack (the Battle of Cambrai (1918)) to complete the penetration and begin the advance beyond the Hindenburg Line.
