List of military engagements of World War I
Battle of Liège
The Battle of Liège was the first battle of the war, and could be considered a moral victory for the allies, as the heavily outnumbered Belgians held out against the German Army for 12 days. From 5–16 August 1914, the Belgians successfully resisted the numerically superior Germans, and inflicted surprisingly heavy losses on their aggressors. The German Second Army, comprising 320,000 men, crossed into neutral Belgium in keeping to the Schlieffen Plan, with the ultimate goal of attacking France from the north. Liège was key strategically as it held a position at the head of a pass through the Ardennes, which made it the best possible route into the heart of Belgium itself.[2]
