Title: Siege of Bergen op Zoom (1588)
Passage: The Siege of Bergen op Zoom was a siege that took place during the Eighty Years' War and the Anglo–Spanish War between September 23 - November 13, 1588.  The siege was between a besieged Anglo Dutch force under Thomas Morgan and Peregrine Bertie and a Spanish besieging force under famed commander Alexander Farnese, the Duke of Parma.  An English officer Grimstone claimed to be a disaffected Catholic had set up a trap during which a large Spanish assault was then bloodily repulsed.  An Anglo Dutch relief column under the command Maurice of Orange soon after arrived and forced the Duke of Parma to retreat, thus ending the siege.
