330 • MARLBOROUGH, DUKE OF
MARLBOROUGH, DUKE OF.In 1701 the Duke of Marlborough ap-
pointed an Irishman, William Cadogan, as his chief of intelligence
for the Wars of the Spanish Succession. He also relied on his private
secretary, Adam de Cardonne, to recruit agents for him. One such
source, named Robethon, who worked for the elector of Brunswick,
sold Marlborough the French plans and their complete order of battle.
Later, when charged with corruption, Marlborough claimed that ‘‘the
contingencies of the army, of which that of Secret Service is the prin-
cipal, was £50,000 per annum’’ and that his allowance for this had
proved insufficient, so he had made up the difference by charging a
commission to the army’s food contractors. The House of Commons
was unimpressed by the argument and when the attorney-general had
announced his intention to prosecute Marlborough, he and Cadogan
left the country for Europe.
