At the end of October 1914, World War I stalled in Flanders Fields. After the first battle of Ypres (October-November 1914), trenches were dug in a wide arc around the city of Ypres. The second battle followed the first gas attack (April 1915). The front line shrank into the “Little Ypres Salient” at 3.5 to 4.5 km away from the city centre. The front started moving again on 7 June 1917. British troops broke open the Ieperboog (Ypres Salient) at the cost of huge losses during the third battle of Ypres (July-November 1917). However the German spring offensive of 1918 pushed the Ypres Salient back towards Ypres. The German troops were forced to give up the Ieperboog at the end of September 1918, due to exhaustion and the arrival of American troops.

These battles almost completely destroyed the city of Ypres, while thousands of citizens and over hundreds of thousands soldiers from around the world lost their lives. More than 150 military cemeteries were built and monuments erected in and around the city in the 1920’s. Cemeteries, monuments, trenches, mine craters and museums nowadays still remind us of the futility of war.
