The immediate causes of the war were seizure of American ships, insults and injuries to American seamen by the British Navy, and rapid expansion of the American frontier. The British outrages at sea took two distinct forms. One was the seizure and forced sale of merchant ships and their cargoes for allegedly violating the British blockade of Europe. Although France had declared a counterblockade of the British Isles and had seized American ships, England was the chief offender because its Navy had greater command of the seas. The British further outraged the United States by capturing men from American vessels for forced service in the Royal Navy. The pretext for impressment was the search for deserters, who, the British claimed, had taken employment on American vessels. | The immediate causes of the war were seizure of American ships, insults and injuries to American seamen by the British Navy, and rapid expansion of the American frontier.
