In February of 1586, the Count Peter Ernst of Mansfeld, by order of Alexander Farnese, laid siege to the town of Grave.[3][4] After three months, and faced with the failure of the English and Dutch forces to relieve the city, Grave surrendered to the Spaniards on 7 June.[1][2] The capture of the strategically important town of Grave by Parma, and the impotence of the English commander Sir Robert Dudley, Earl of Leicester, to relieve the town, in a time where England had raised hopes to the Dutch rebels thanks to the Treaty of Nonsuch, was a complete military and political success for the Spanish authorities, and a severe blow for the Protestant cause, provoking the start of the disagreements of the States-General of the Netherlands with the Earl of Leicester.[1][2][5]
