This article continues an examination of the British government's counter-revolutionary organization begun in ‘The Alien Office 1792-1806’, The Historical Journal, XXXIII (1990), which outlined the department's functions and secret service policy. The Swiss and Swabian agencies were one aspect of British foreign secret service; they linked the French princes' secret agents to the British government under the central European control of William Wickham, ambassador in Berne 1794–7, and military and diplomatic subsidiaries. Anti-republican secret committees were set up covering all France, Switzerland, northern Italy and southern Germany, which included members from every grade of society. French republican generals, even Ministers were swayed, allowing infiltration of the French secret police. British control was however limited to the finesse of finance – bribery was implicit. By never offering enough to the leaders and too much to assistants, initial constitutional intentions slid into subversion and assassination. The first complete andfully documented description is included of how, why, and by whom, the French deputies were assassinated at Rastadt.
