In 1629 a high ransom was paid for prior Martinus Pauli who had been captured by Dutch militia near Liège and was kept prisoner in Emmerich. More wartime hardship came with the Capture of Maastricht by the Dutch in 1632 and the Capture by the French in 1673. After the siege of 1673, Louis XIV of France donated 2100 guilders to the monastery for repairs. After the French left in 1678, the monastery suffered from forced billeting of the Dutch garrison.
