Second Battle of Ypres

Second Battle of Ypres was a major engagement of the First World War fought from 22 April to 25 May 1915 for control of the strategic Flanders town of Ypres. It is historically notorious for the first large-scale use of chemical weapons on the Western Front by the German Empire. The battle, which included the heroic stand of the 1st Canadian Division at the Battle of St. Julien, ultimately resulted in a bloody stalemate but significantly contracted the Ypres Salient held by the Allied forces.

Background

By the spring of 1915, the Western Front had solidified into a network of opposing trench lines following the First Battle of Ypres in late 1914. The German High Command, seeking to test a new weapon and potentially break the deadlock around the critical Ypres Salient, deployed specialized pioneer troops from Pionier-Regiment 35 under the command of Albrecht, Duke of Württemberg. The Allied forces defending the salient were a mix of the British Expeditionary Force, including the Indian Army, the Canadian Expeditionary Force, and the French Army under General Henri Gabriel Putz. The strategic aim for Germany was to divert Allied resources from the Eastern Front and capture the high ground of the Yser canal.

The battle

The battle commenced on the afternoon of 22 April 1915 with the release of 168 tons of chlorine gas from cylinders near Langemark, which drifted across the lines held by the French 45th Algerian Division and the French 87th Territorial Division. This first large-scale chemical attack created a massive breach in the Allied line. The 1st Canadian Division, positioned north of the city, famously plugged the gap during the ensuing Battle of Gravenstafel, despite having only primitive gas masks. Fierce fighting continued for control of key terrain, including the Battle of Frezenberg and the Battle of Bellewaarde. A second major gas attack on 24 April targeted the Canadian sector at the Battle of St. Julien, but the line held. Subsequent German assaults, including the capture of Hill 60, were met with determined resistance from units like the Princess Patricia's Canadian Light Infantry and the British 27th Division.

Aftermath

The battle concluded in a tactical stalemate on 25 May, with the German Army failing to capture Ypres. However, the Allied forces were forced to withdraw to a new, smaller defensive line closer to the city, significantly reducing the Ypres Salient. Casualties were immense, with the British Empire suffering between 59,000 and 70,000 casualties and Germany between 35,000 and 40,000. The use of poison gas was universally condemned, leading to swift diplomatic protests and later the Hague Convention. The performance of the Canadian Expeditionary Force under commanders like Sir Arthur Currie garnered significant recognition and marked a pivotal moment in the development of Canadian nationalism. The battle also demonstrated the urgent need for effective gas masks, which were rapidly developed by the Allies.

Legacy

The Second Battle of Ypres is primarily remembered for the horrific introduction of chemical warfare to modern conflict, a tactic that would be used repeatedly throughout the First World War, including at the Battle of Loos. The defense mounted by the Canadian Corps became a foundational legend of Canadian military history, commemorated at sites like the Saint Julien Memorial and the Brooding Soldier monument. The battle highlighted the brutal, attritional nature of warfare on the Western Front, setting a grim precedent for later engagements like the Battle of Verdun and the Battle of the Somme. It remains a central subject of study for historians of World War I and is memorialized annually in Canada on Remembrance Day.
