A study of the hardening of British public opinion against Bonaparte and an examination of the events that caused it.

In 1801 Britain and Bonaparte made an armistice, which became the Treaty of Amiens in March 1802. In the brief period of peace which followed, British attitudes underwent a major change, so that when war began again in May 1803 there was little or no dissent from the view that the war had to be fought to a finish and Bonaparte's power destroyed. This was partly the result of Bonaparte's underhand methods during negotiations; but it was also due to the conclusion reached by the many British visitors to France during the interval of peace that Bonaparte was extremely dangerous, anger at his stealthy political advances in Europe and America, and outrage at his detention and imprisonment of British civilians when war began again. The attitude of the British government headed by Henry Addington, and in particular the diplomatic methods of the Foreign Secretary Lord Hawkesbury (later the Prime Minister Lord Liverpool) were decisive in countering Bonaparte's methods; they receive their due in this first detailed examination of events, based on original materials.
