Vimy Ridge: a journey of maps (part 1)

By Ethan M. Coudenys

Cartography is the practice of drawing or making maps; during the First World War, this was vital for planning and preparing attacks and defensive actions. Battles in France like those of the Marne, Somme and Verdun were mostly planned with large maps by high-ranking officers and non-commissioned members. However, for the battle at Hill 145—better known as Vimy Ridge—cartography played an integral role in the planning of the assault by the Canadian Expeditionary Force (CEF).

Before we begin, we should set the scene by talking about the CEF before the Battle of Vimy Ridge. The Canadians had fought in various battlefields in France and Belgium, including with distinction at Flers-Courcelette (August–November 1916) in France, about 50 kilometres from Vimy. Under the command of Lieutenant-General (later Field Marshal and Governor General) Sir Julian Byng, the CEF had become a very successful fighting force. In November 1916, the Canadians began moving to the east of the French town of Arras. There, they began preparing for an attack on Hill 145, where the German forces had taken nearly three years to build very heavily fortified lines of trenches.

The Battle of Vimy Ridge, which began on April 9, 1917, was not an isolated operation; it was a small part of the Battle of Arras. The two major points of the battle for the ridge, for which the Canadians were responsible, were the ridge itself (Hill 145) and the Pimple (Hill 119). Incredible preparations went into planning this attack.

Between the beginning of the war in 1914 and when the Canadians took up positions in late November 1916, French and Moroccan divisions had tried to take Vimy Ridge. They advanced the allied front line closer to the ridge. During the Battle of Verdun, the British took over these positions, and they expanded and strengthened the relatively weak fortifications. By November 1916, the CEF entered the front line at Vimy with very good fortifications.

The Canadians were called to the line at Vimy for the first time as an entire corps, fighting side by side. This was incredibly important not only for the soldiers but also for the young nation. For many, it signified the start of a process whereby Canadians would collectively build their cultural and national identity.

We can better understand the importance of cartography in battle by first reviewing some of the maps that are presented today at the Visitor Education Centre in the Canadian National Vimy Memorial in France. There, Canadian guides—all university and college students—educate the public about the Battle of Vimy Ridge, including the tunnels that were built to support the advance of Canadian troops in April 1917. In maps 1 and 2, the different tunnels and trench lines used during the battle for the ridge are shown.

How were the maps made?

Maps were important for infantry soldiers because they helped to ground and situate them in an environment marked by constant fear, confusion and proximity of death. During the months leading up to the Vimy Ridge battle, soldiers were sent into the German forces’ trenches to gain information about the enemy’s fortifications and weapon emplacements that lined the front. Moreover, the Royal Flying Corps (later the Royal Air Force) used aerial photography to pinpoint areas of fortifications and map points of interest for the attack. Let us examine this gathering of information by soldiers.

The CEF collected information by sending small incursions into the German lines, with soldiers memorizing the layouts of the other side’s trench systems. These could be completed by a small group of men or a very large group (5,000 or more in one instance) and took place from November 1916 until the eve of the battle in April 1917.

During the infamous trench raids, Canadian soldiers would be tasked with memorizing the layout of the trenches and important locations in the German forces’ lines. These vital recollections were later reflected in detailed maps, which were used by the Canadians to help reduce confusion among the infantry. The trench raids could be incredibly dangerous, both for the men raiding and for the defenders. Often these attacks would take place at night, and both attackers and defenders could suffer heavy losses.

The maps that were created as a result of these raids, such as the example above, were often drawn by hand, from memory, by individual soldiers.

What maps were made?

We are very fortunate to have access to a vast number of maps from the Great War in the collection at Library and Archives Canada. Some of the most frequently requested by researchers are the trench line maps of the Western Front. As mentioned above, these maps were drawn through painstaking and sometimes bloody collection of information by soldiers, engineers and pilots. These maps were issued widely to both low-ranking officers and non-commissioned members of the infantry to help them succeed in the attack on April 9, 1917.

The first map issued, and perhaps the most important for the advance, was the barrage map. During the attack on Vimy Ridge, the Canadian artillery, supported by numerous British field artillery units, used the tactic of a rolling (or creeping) barrage to subdue resistance by the German forces while the infantry advanced behind a wall of falling shells. This process was incredibly well timed, and it needed to be, to avoid any friendly fire casualties. Thus, maps were created and used by the artillery units to launch this barrage on the German forces’ lines. These maps detail the targets of the artillery leading up to the four main objectives of the CEF between April 9 and 12, 1917. They show the 100-metre advances of the rolling barrage every three minutes, allowing the infantry units following the barrage to successfully move behind the wall of fire. The maps also show the various targets of particular interest, including fortifications, machine gun emplacements, mortar emplacements and munitions storage areas.

The most widely used maps in the attack on Vimy Ridge were those issued to infantry units. These maps were small copies of larger planning maps used by high-ranking officers, but they included the individual objectives of each platoon and company. This was an incredibly important step in planning and executing the attack on the ridge. Despite the confusion caused by gun and rifle fire, the maps helped the advancing soldiers to stay on course.

The change of policy allowing soldiers to carry their own battlefield maps might seem like a minor one, but it had a significant effect on the CEF’s success in the Battle of Vimy Ridge.

“It made you intensely proud to see it standing there”: How the Vimy Memorial survived the Second World War

By Andrew Horrall

Canadian Army Newsreel No. 42 must have been very exciting to watch in September 1944. In an era before television, cinema audiences followed the events of the Second World War through these short films.

Scenes of liberated cities in this newsreel indicated that the war in Europe had entered its final phase. A particularly poignant segment showed Lieutenant-General Harry Crerar, commander of the Canadian Army, visiting the Canadian National Vimy Memorial, which commemorates the Battle of Vimy Ridge in the First World War.

The Vimy Memorial, which was unveiled in 1936 before thousands of Canadian veterans and their families, dominates the battlefield and is the most moving shrine to Canada’s wartime sacrifices. Photographs of Adolf Hitler visiting the memorial soon after it was captured by the Germans in 1940 were the last images that Canadians had seen of it, and many believed it had been destroyed. When Canadian war correspondent Ross Munro visited the newly liberated memorial on September 1, 1944, he marveled that it “seemed almost as if it had been swept and polished for this visit, but it had been like this through four years of war. It made you intensely proud to see it standing there, a symbol of the gallantry and sacrifice of the last war and which might well become the same for this war.”

Newsreel images of General Crerar’s entourage walking across well-tended grounds to the memorial, which gleamed in the late-summer sun, confirmed Munro’s description. The group was followed by a man in a tweed jacket and beret who was eventually seen speaking with Crerar as the narrator proclaimed, “Even during the occupation, the caretaker kept the Vimy Memorial grounds in order.”

The man in the newsreel was Paul Piroson. Still photographs taken during the visit also show Crerar talking to George Stubbs, who seems too old for his private’s uniform. The two men told Crerar about how they and their wives had safeguarded the memorial during the German occupation.

George Stubbs was an English-born butcher who joined the Canadian Expeditionary Force in Winnipeg in 1914. He fought at Vimy Ridge, married a woman named Blanche in 1919 and settled in England.

Like many veterans, Stubbs had been deeply moved by the war. He returned to Vimy in the early 1920s, paying tribute to those with whom he had served by helping the Canadian government to preserve the battlefield. Piroson, who had grown up nearby, was hired at about the same time.

Stubbs became a familiar figure at Vimy, helping to build the memorial and explaining the valour and sacrifice of Canadians to thousands of visitors each year. When the memorial was unveiled, he became its official caretaker.

George and Blanche Stubbs decided to remain at Vimy with their four children when the Second World War started in 1939. The Allies still controlled France the following spring, when George sent $25 to the Canadian Legion, expressing a desire to help “those of my comrades who are not so fortunately placed as myself.” The words seem ironic today, because the Germans overran France within weeks, sending the Stubbs family racing to the port of Bordeaux in hopes of escape. They were too late and went into hiding, but were arrested in October 1940.

George Stubbs spent the rest of the occupation in an internment camp near Paris, while Blanche and the children returned to the family cottage at Vimy, where they reunited with Paul Piroson and his wife Alice.

The trio of adults ensured that the memorial was treated respectfully while in enemy hands, by explaining to German soldiers about its significance and also preventing damage from vandals. While they were outwardly courteous and deferential, Paul hid weapons for the Resistance in the tunnels under the battlefield.

When George Stubbs was liberated in August 1944, the Canadian Army provided him with the uniform he wore to meet Crerar. Though Stubbs was a civilian, these were likely his first new clothes in years. George then joined Blanche and the Pirosons at Vimy, where they greeted Allied soldiers, told their stories to reporters, and hired local workers to clean and repair the site.

George and Blanche Stubbs stayed at Vimy until 1948, when they returned to Canada. After experiencing two world wars, it is not surprising that George proclaimed he would never go back to Europe.

Paul Piroson succeeded George Stubbs as the Vimy Memorial’s caretaker, protector and guide. The Pirosons were devoted to Canada, a country they had never visited at the time. The couple named their cottage “The Maple Leaf” and always wore the symbol on their jackets. Though only Paul was paid, the pair both led tours and enforced a strict, old-fashioned reverence for the site—women were not permitted to wear shorts, children had to be well behaved, and food was forbidden. Each year on Remembrance Day, Paul laid a wreath for the Canadian government.

When Paul retired in 1965, veterans convinced Prime Minister Lester B. Pearson to invite the Pirosons to Canada as official guests for the 50th anniversary of the Battle of Vimy Ridge. Though Pearson’s invitation dates from a time when women’s work was regularly overlooked, he thanked the pair equally for their “close personal association with so many Canadian service personnel during both world wars, your great kindness to so many of them and your hospitality and help to Canadians who have returned to Vimy Ridge.”

The Pirosons took part in Vimy commemorations across Canada in 1967. When a reporter asked about their impressions of the country they had represented for so long, Alice replied, “We both think a lot of Canadians.” Her simple words expressed the deep gratitude for Canadian wartime sacrifices that had inspired the devotion of the Stubbs and Piroson families to the Vimy Memorial.
