Operation Market Garden Anniversary is observed in the Netherlands every September 17. This date commemorates the anniversary of Operation Market Garden, a significant but ultimately failed military operation conducted by the Allies during the Second World War. The operation, planned by British Field Marshal Bernard Montgomery, aimed to secure bridges and facilitate an entry into Germany by crossing the Lower Rhine. On September 17, 1944, Allied airborne troops landed in the Netherlands, successfully capturing several bridges between Nijmegen and Eindhoven. However, due to various factors, including defeat at the Battle of Arnhem, they were unable to cross the Rhine, leading to operational failure by September 25. Although not an official remembrance day, the anniversary is marked by special memorial ceremonies across the country, including wreath-laying at monuments and other commemorative events.
