Which battle featured the first large-scale use of chlorine gas on the Western Front?

• A. Second Battle of Ypres
• B. Battle of the Somme
• C. Battle of Verdun
• D. Battle of Jutland

Answer: (A)

The main idea being tested is when chemical warfare first appeared on a large scale on the Western Front and how it changed fighting conditions. In 1915, at the Second Battle of Ypres in Belgium, German forces released a substantial cloud of chlorine gas across Allied trenches. This was the first time a major power employed chlorine gas in such a broad, coordinated way, turning a stretch of trench warfare into a toxic battleground. The gas stunned troops, caused severe breathing and eye injuries, and forced a retreat from exposed positions. The moment proved that gas could alter the battlefield, prompting the rapid development of protective measures like gas masks and influencing how both sides planned and conducted combat thereafter. The other battles listed don’t fit this first-use criterion. The Battle of the Somme and the Battle of Verdun were enormous artillery-driven battles that occurred after 1915 and did not mark the initial large-scale chemical attack. The Battle of Jutland was a naval engagement in the sea, not a land battle on the Western Front, so it involved no chlorine gas usage.
