The seizure of the Danish fleet, in time of so-called peace, roused great indignation throughout most of Europe, and, in some degree, strained the conscience of the British parliament itself. The justice and wisdom of it were strenuously challenged in both houses, especially by Grenville, Sidmouth, and Lord Darnley, who moved an address to the crown embodying an impressive protest against it. It was defended, however, by the high authority of the Marquis Wellesley, as well as by Canning and other ministers, on the simple ground of military necessity. Napoleon himself never ceased to denounce it as an international outrage of the highest enormity. This did not prevent his doing his best to justify it and to imitate it by sending Junot's expedition to Portugal, with instructions to seize the Portuguese fleet at Lisbon. It is strange that in the debates on this subject, peace with France was still treated on both sides as a possibility; but Canning declared that neither Russian nor Austrian mediation could have been accepted as impartial, or as affording the least hope of pacification. However, on September 25, the king addressed a declaration to Europe, in which, after justifying himself in regard to Copenhagen, he professed his readiness to accept conditions of peace "consistent with the maritime rights and political existence of Great Britain". [Pageheading: _COMMERCIAL EXCLUSION._] Still more reasonable attacks, supported by strong petitions, were made by the opposition upon the "orders in council," whereby the British government retaliated against Napoleon's "continental system". This system was founded on a firm belief, shared by the French people, that Great Britain, as mistress of the seas, was the one great obstacle to his imperial ambition, and the most formidable enemy of French aggrandisement, only to be crushed by the ruin of her trade. Prussia had, in conformity with her treaty of February 15, 1806, issued a proclamation on March 28 of that year, closing her ports, which would now include those of Hanover, against British trade. The British government replied by first laying an embargo on Prussian vessels in the harbours of Great Britain and Ireland, and by proclaiming a blockade of the coast of Europe from Brest to the Elbe. This was followed on May 14 by an order in council for seizing all vessels found navigating under Prussian colours. As yet the policy of commercial exclusion had not been carried to any great length, but the Berlin decree issued by Napoleon on November 21 after the battle of Jena proclaimed the whole of the British Isles to be in a state of blockade, prohibited all commerce with them from the ports of France and her dependent states, confiscated all British merchandise in such ports, and declared all British subjects in countries occupied by French troops to be prisoners of war. Howick replied by further orders in council in January, 1807, forbidding
