The Conde de Barca, then prime minister, was certainly aware of the preparations of the French government. But with that obstinate blindness which sometimes seems to possess men like a fate, he persisted in regarding them only as measures to intimidate and harass England. This nobleman had been ambassador at the court of St. Petersburg, and on his recall to take the first place in the cabinet at Lisbon, he was ordered to go by sea to London, and thence to Portugal, but he chose to perform the journey by way of Paris, where he saw and conversed both with Napoleon and Talleyrand. There cannot be the least doubt but that he was duped by those able men. Many considered him as a traitor. But the vanity of the Conde, who always said he had gone to judge of these men by his own eyes, though it makes him weaker, makes him less wicked, and was, perhaps, the true spring of his actions. He it was who carried the measures for the detention of the English, the confiscation of their property, and the shutting the ports against English commerce: adopting, in short, the whole of the continental system. The very day before Junot was to reach Lisbon, however, a Paris newspaper, written in anticipation of the event, announced that "The House of Braganza no longer reigned," and that its members were reduced to the common herd of ex-princes, &c., giving no very favourable description of them, and holding out no very flattering expectations for the future. This completely opened the Prince Regent's eyes, and he consented to that step, which D. John IV. and Don José had contemplated, namely, the transferring the seat of his empire to his Transatlantic possessions.

This was in the month of November, 1807, but the events of that month, the most interesting that had occurred to Portugal since the revolution that had placed Braganza on the throne of his ancestors, will be best understood by the following extracts from the despatches received by the British ministry from Lord Strangford and from Sir Sydney Smith at the time. On the 29th November, 1807, His Lordship writes, after mentioning the Prince's departure for Brazil:—

"I had frequently and distinctly stated to the cabinet of Lisbon, that in agreeing not to resent the exclusion of British commerce from the ports of Portugal, His Majesty had exhausted the means of forbearance; that in making that concession to the peculiar circumstances of the Prince Regent's situation, His Majesty had done all that friendship and the remembrance of ancient alliance could justly require; but that a single step beyond the line of modified hostility, thus most reluctantly consented to, must necessarily lead to the extremity of actual war.

"The Prince Regent, however, suffered himself for a moment to forget that, in the present state of Europe, no country could be permitted to be an enemy to England with impunity, and that however much His Majesty might be disposed to make allowance for the deficiency of means possessed by Portugal of resistance to the power of France, neither his own dignity nor the interests of his people would permit His Majesty to accept that excuse for a compliance with the full extent of her unprincipled demands. On the 8th inst. His Royal Highness was induced to sign an order for the detention of the few British subjects, and of the inconsiderable portion of British property which yet remained at Lisbon. On the publication of this order, I caused the arms of England to be removed from the gates of my residence, demanded my passports, presented a final remonstrance against the recent conduct of the court of Lisbon, and proceeded to the squadron commanded by Sir Sydney Smith, which arrived off the coast of Portugal some days after I had received my passports, and which I joined on the 17th inst.

"I immediately suggested to Sir Sydney Smith the expediency of establishing the most rigorous blockade at the mouth of the Tagus; and I had the high satisfaction of afterwards finding that I had thus anticipated the intentions of His Majesty: for despatches (which I received on the 23d) directing me to authorise that measure, in case the Portuguese government should pass the bounds which His Majesty had thought fit to set to his forbearance, and attempt to take any further step injurious to the honour or interests of Great Britain."—

----"I resolved, therefore, to proceed forthwith to ascertain the effect produced by the blockade of Lisbon, and to propose to the Portuguese government, as the only condition upon which that blockade should cease, the alternative (stated by you) either of surrendering the fleet to His Majesty, or of immediately employing it to remove the Prince Regent and his family to the Brazils."—

"I accordingly requested an audience of the Prince Regent, together with due assurances of protection and security; and upon receiving His Royal Highness's answers I proceeded to Lisbon on the 27th, in His Majesty's sloop Confiance, bearing a flag of truce. I had immediately most interesting communications with the court of Lisbon, the particulars of which shall be detailed in a future despatch. It suffices to mention in this place, that the Prince Regent wisely directed all his apprehensions to a French army, and all his hopes to a British fleet: that he received the most explicit assurances from me that His Majesty would generously overlook those acts of unwilling and momentary hostility to which His Royal Highness's consent had been extorted; and that I promised to His Royal Highness, on the faith of my sovereign, that the British squadron before the Tagus should be employed to protect his retreat from Lisbon, and his voyage to the Brazils.

"A decree was published yesterday, in which the Prince Regent announced his intention of retiring to the city of Rio de Janeiro until the conclusion of a general peace, and of appointing a regency to transact the administration of government at Lisbon, during His Royal Highness's absence from Europe."

Sir Sydney Smith writes on the first of December the following letter to the admiralty:—

His Majesty's Ship Hibernia, 22 leagues west of the Tagus, Dec. 1, 1807.
