The vast military exertions of the French republic had carried many hands from their usual occupations, to the field; and the measures of government, added to the internal commotions, had discouraged labour by rendering its profits insecure. These causes, aided perhaps by unfavourable seasons, had produced a scarcity which threatened famine. This state of things suggested to their enemies the policy of increasing the internal distress, by cutting off the external supply. In execution of this plan, the British cruisers were instructed "to stop all vessels loaded wholly or in part with corn, flour, or meal, bound to any port in France, or any port occupied by the armies of France, and to send them to such ports as shall be most convenient, in order that such corn, meal, or flour, may be purchased on behalf of his majesty's government, and the ships be relieved after such purchase, and after a due allowance for freight; or that the masters of such ships on giving due security, to be approved by the court of admiralty, be permitted to proceed to dispose of their cargoes of corn, meal, or flour, in the ports of any country in amity with his majesty." In the particular character of the war, and in the general expressions of some approved modern writers on the law of nations, the British government sought a justification of this strong measure. But by neutrals generally, it was deemed an unwarrantable invasion of their rights; and the remonstrances made against it by the American government in particular, were serious and earnest. This attempt to make a principle, which was understood to be applicable only to blockaded places, subservient to the impracticable plan of starving an immense agricultural nation, was resisted with great strength of reasoning by the administration; and added, not inconsiderably, to the resentment felt by the body of the people.[11] [Footnote 11: See note No. VI. at the end of the volume.] Hostilities on the ocean disclosed still another source of irritation, which added its copious stream to the impetuous torrent which threatened to sweep America into the war that desolated Europe. The British government had long been accustomed to resort to the practice of manning their fleet by impressment. The exercise of this prerogative had not been confined to the land. Merchantmen in their ports, and even at sea, were visited, and mariners were taken out of them, to be employed in the royal navy. The profits of trade enabling neutral merchants to give high wages, British sailors were tempted, in great numbers, to enter their service; but the neutral ship furnished no protection. Disregarding the bottom in which they sailed, the officers of the navy impressed them wherever found, often leaving scarcely hands enough to navigate the vessel into port.
