WW2 during stage 1.

The Battle of Maastricht was one of the first battles that took place during the German Campaign on the Western Front during World War II. Maastricht was a key city in order to capture the Belgian Fort Eben-Emael and split the allied armies in half.

The German goal of the operation was to take the bridges over the river Maas intact, in order to have an easier road to France. Therefore, the Germans sent in teams disguised as civilians whose jobs were to sabotage the bridge charges. However, they were spotted and arrested.

The battle won by the Germans marked the beginning of the occupation of Maastricht, which would last four years, four months and four days.
