On the morning of 9 April 1917, four divisions of the Canadian Corps rose from their trenches in the Pas-de-Calais and began climbing a frozen, shell-pocked escarpment that two years of French offensives had failed to take. By nightfall, most of Vimy Ridge was in Canadian hands. The battle lasted just four days. Its shadow has lasted more than a century.
A Ridge That Refused to Fall
To understand why Vimy Ridge mattered, you have to understand what it was. Rising gradually on its western face and dropping sharply on the eastern side, the ridge sits about 8 kilometres northeast of Arras, at the edge of the Douai Plain. From its highest point — roughly 145 metres above sea level, or about 60 metres above the plains below — the terrain offered an unobstructed view for tens of kilometres in every direction. Whoever held the ridge held the eyes of that entire stretch of the front.
Germany had held it since October 1914, seized during the frantic back-and-forth of the Race to the Sea, when Franco-British and German forces tried to outflank each other through northeastern France. After that, the French tried twice to take it back. During the Second Battle of Artois in May 1915, the French 1st Moroccan Division actually managed to reach the crest — briefly — before collapsing back for lack of reinforcements. A second attempt in September 1915 gained only the village of Souchez at the western base of the ridge. By the time French forces handed the sector to British troops in February 1916, France had suffered approximately 150,000 casualties trying to dislodge the Germans from Vimy Ridge alone. The ridge had become a kind of monument to futility.
Planning a Different Kind of Attack
When the Canadian Corps relieved British forces along the western slopes in October 1916, they inherited both the ridge problem and the bitter lessons of everyone who had tried before them. What they did with those lessons made all the difference.
Planning for what would become the Battle of Vimy Ridge began in earnest at a corps commanders’ conference in November 1916. In January 1917, three Canadian Corps officers attended French Army lectures on the Battle of Verdun, where General Robert Nivelle’s counter-offensive had achieved notable success through a combination of overwhelming artillery and infantry flexibility. The officers came back and produced a detailed tactical analysis, delivering lectures at the corps and divisional level that stressed the primacy of artillery, the value of harassing fire, and the importance of giving companies and platoons room to adapt on the fly.
Arthur Currie, commanding the 1st Canadian Division, was among those who drew lessons directly from the Verdun experience. The final assault plan reflected that thinking closely. The Canadian Corps attack would unfold in four coloured objective lines — Black, Red, Blue, and Brown — with infantry advancing in timed increments behind a creeping barrage of field guns, while medium and heavy howitzers hammered defensive positions further ahead. Units would leapfrog one another to maintain momentum. The geometry of the plan was designed so that, if the schedule held, the ridge would be largely in Canadian hands by 1:00 pm on the first day.
The Weight of the Guns
What made the plan credible was the firepower behind it. The artillery assembled for Vimy Ridge was staggering by the standards of any previous operation in the sector. Four hundred and eighty 18-pounder field guns, 138 howitzers, and hundreds of siege guns and heavy mortars were brought to bear. The density worked out to one heavy gun for every 20 metres of front, and one field gun for every 10 metres — three times the concentration of heavy artillery used at the Battle of the Somme in 1916.
Brigadier-General Edward Morrison produced a 35-page artillery instruction document — Canadian Corps Artillery Instruction No. 1 for the Capture of Vimy Ridge — detailing a multi-phased fire support plan. The preparatory bombardment was not a sudden shock but a sustained, methodical effort designed to suppress German defenders, destroy their machine gun positions, and keep them pinned underground at the moment the infantry advanced. The Canadians were also not going in blind: the extensive German tunnel network in the sector, the layout of their defensive positions, and even the disposition of their reserves were known in detail before the attack began.
Four Days on the Ridge
The attack opened on 9 April 1917 — Easter Monday — with all four Canadian divisions advancing together for the first time in the war. The Canadian Corps captured most of the ridge on that first day. On the second day, the village of Thélus fell, along with the crest of the ridge, after hard fighting through a German salient. The final objective — a fortified knoll outside the village of Givenchy-en-Gohelle, known in the plan as the Pimple — fell on 12 April. The German 6th Army retreated to the Oppy–Méricourt line.
The German position had not been strong in ways that the ridge’s fearsome reputation might suggest. The new German defensive doctrine, published by Ludendorff in December 1916, called for elastic defence in depth — flexible garrisons with room to manoeuvre, rather than rigid lines. But the terrain at Vimy Ridge made that doctrine nearly impossible to implement. At its narrowest, the ridge was only 700 metres across, with a steep drop on the eastern side that all but eliminated the possibility of counterattacks once the crest was lost. German commanders knew this was a weakness. Their reserve divisions were kept roughly 15 miles back, in keeping with the new doctrine’s theory, which meant they couldn’t respond quickly when the Canadian advance moved faster than expected. Each German rifle company at Vimy contained around 150 men — well below the full-strength figure of 264 — facing two or more full Canadian battalions.
Historians have pointed to several interlocking reasons for the Canadian success: technical and tactical innovation, meticulous planning, overwhelming artillery support, extensive training, and the failure of the German 6th Army to properly apply its own new defensive doctrine. The Canadians were not simply lucky. They had studied, prepared, and rehearsed in ways that earlier attacks on the same ground had not.
What We Still Don’t Know
The battle’s status as a symbol of Canadian national identity is well established — but also contested in ways the historical record reflects honestly. The claim that Vimy Ridge was the moment “Canada became a nation” is a narrative that developed over decades after the war, and historians continue to debate how much of that symbolism was constructed retrospectively rather than felt in the moment. The Wikipedia sources on the battle describe it as “made a symbol of Canadian national achievement and sacrifice” — the passive construction is telling. Symbols are made, not born.
There are also genuine military questions that remain open. The battle was the first time all four Canadian divisions fought together, but the contribution of attached British units — including the 5th Division and extensive artillery and engineering support — to the outcome is not always fully accounted for in popular tellings. The precise role of individual tactical decisions, versus the weight of materiel advantage, in producing victory is the kind of question that military historians continue to argue.
What is not in doubt is the human cost, or the scale of the achievement relative to what had come before. Where 150,000 French casualties had failed to take the ridge, four Canadian divisions took it in four days. The 100-hectare memorial park that now covers part of the battleground, and the Canadian National Vimy Memorial that stands on it, mark a place where something remarkable happened — even if exactly what it meant, and to whom, is still being worked out.
