Willem van Oranje
Despite these orders and the letters of marque many vessels of nations other than those of Spain were attacked by the Sea beggars. Even fishing-boats and merchant vessels of the Dutch Provinces were not safe from attack. A case in point was Lord De Dolhain. For several months in 1570 he acted as Admiral for the Prince of Oranje. Because he refused to render any accounts of his expeditions he was deprived of his command. In a letter to the Church in London, dated 26 February 1573, the Prince remarked on one of the reasons why the Sea beggars often attacked ships indiscriminately: they earned their meals through the mouths of their Cannons.
