Napoleon's Wars_ An International History, 1803-1815 - Charles Esdaile [202]
For victory to come, then, Napoleon probably had only to wait. Waiting, though, was not in his nature and he remained obsessed by the constant need to secure fresh triumphs and thereby, as he put it, ensure that he continued to be feared. Worth citing, too, is the fact that the departure of Talleyrand had removed at least a possible restraining influence. Talleyrand may not have been quite the force for good that he always claimed, but his successor as Foreign Secretary, Champagny, was not nearly so independent a figure. At all events, no sooner were the discussions at Tilsit over than Napoleon was looking around for a new target. The obvious choice was Portugal, and all the more so as an attack on that state had been aborted by the campaign of Jena and Auerstädt. Pretexts for an attack were plentiful: Portugal was not part of the Continental Blockade, had been defaulting on the indemnity she had been paying France since the ‘War of the Oranges’ of 1801, and had frequently allowed British warships to revictual from her shores. And there was much to gain: Portugal possessed wealthy colonies and a fleet that, if no great size, was not to be despised, while Lisbon was a vital base that offered major advantages to whichever side could incorporate it into their war effort. And finally she ought to present few problems. Her army was minimal and her ruler, the Prince Regent John, notoriously dull-witted, while the agreement of the Russians to evacuate the Ionian islands and in effect join the French meant that it might even be possible to attack Lisbon from the sea, as the Russian commander in the Adriatic, Admiral Senyavin, would have to pass that way as he brought his forces home to St Petersburg.
Behind all this the issue of genuine strategic requirements is discernible. Should any defender of Napoleon wish to do so, it is possible to argue that what mattered in the end was always the war against Britain. Thus, successive British Cabinets had refused to give in, and so the emperor needed all the ships and all the coasts that he could obtain. To quote a letter written by Napoleon to Charles IV to justify the attack on Portugal, ‘We can only obtain peace by isolating England from the Continent and closing the latter’s ports to her commerce. I count on Your Majesty’s energy in securing this objective: if tranquillity is to be restored in the world, England must be forced to make peace.’14 Nor should it be forgotten that Britain had attacked Copenhagen
