Between July and September 1602 the Spanish-held town of Grave was besieged and captured by the Dutch and English army led by Maurice and Francis Vere respectively.
[8] This was the 10,000 troops under Frederik van den Bergh who had marched from Ostend collecting reinforcements on the way, including many Italians, hoping to recapture the town and shore up its defences.
[9] When Maurice provided them with a cavalry force they became a bigger threat and it was only then that the Archduke decided to ratify a treaty that granted a complete pardon despite the protests of Spain and the council of state.
[5] The mutiny had a severe effect on Spanish military operations, with the Archduke fearing that it might force the abandonment of the Siege of Ostend.
[2] An important source for the organisation of the mutiny is the autobiography of Charles Alexandre de Croÿ, Marquis d'Havré, who was a hostage of the mutineers for eleven months.
