Details: Capture of Brielle - Procession April 1st, 1572 - the capture of Brielle by the Watergeuzen. A turning point in the uprising of the Low Countries against Spain in the Eighty Years' War. Militarily the success was minor as the port of Brielle was poorly defended by the Spanish, but it provided the first foothold on land for the rebels at a time when the rebellion was all but crushed, and it offered the sign for a new revolt throughout the Netherlands which led to the formation of the Dutch Republic.

The Watergeuzen were led by William van der Marck, Lord of Lumey, and by two of his captains, Willem Bloys van Treslong and Lenaert Jansz de Graeff. After they were expelled from England by Elizabeth I, they needed a place to shelter their 25 ships. As they sailed towards Brielle, they were surprised to find out that the Spanish garrison led by the Spanish "Iron" Duke of Alva protagonists was poorly defended. On the evening of April 1 in 1572, the 600 men sacked the port, rammed the city gates, defeated the Spanish soldiers and liberated Brielle as the first Dutch city in the Netherlands from de Spanish .

Nowadays a very popular annual UNESCO event with lots of Watergeuzen, Spanish soldiers and medieval dressed people in a city center all dressed up just like then on that historical day.
