The same remarks apply to the martello towers. The responsibility for them rests mainly with Colonel Twiss and Captain Ford, who in the summer of 1803 recommended their construction at exposed points of the shore, at a cost of about £3,000 apiece. The experience of our troops in Corsica showed that such towers, even when held by small garrisons, could hold at bay a greatly superior force.[694] The towers were begun soon afterwards; but those in Pevensey Bay were not undertaken till 1805–6. The first points to be defended were those nearest to France.
In the winter of 1804–5 there was need to strengthen the coast defences; for the declaration of war by Spain placed the whole of the coast line from the Texel to Toulon at Napoleon's disposal for shipbuilding. There seemed therefore every prospect of our being finally overwhelmed at sea, a consummation which the French Emperor might have ensured had he refrained from irritating the monarchs of Russia and Austria. Fortunately for England, his nature was too restless and domineering to admit of the necessary concentration of effort on the naval problem; and that besetting sin, megalomania, marred prospects which then seemed easily realizable. Playing with coolness and patience, he had the game in his hands in 1804, when as yet there was little prospect of an Anglo-Russian alliance.
An offensive alliance of Spain with France was the natural result of the treaty of 1796 between the two Powers. In vain did the luxurious Charles IV and his pampered minion, Godoy, Prince of the Peace, seek to evade their obligations. Under threat of a French invasion they gave way and agreed to pay 72,000,000 francs a year into the French exchequer, and to force the hand of Portugal. That little Power purchased immunity for a time by paying an annual subsidy of 12,000,000 francs to France. Spain also repaired French warships which took refuge at Ferrol in July 1804, and allowed reinforcements to their crews to travel thither overland. When Pitt and Harrowby remonstrated on this conduct, Spain armed as if for war; and in answer to inquiries from London, Godoy alleged certain disputes with the United States as the cause of his alarm. The arrival in London of Frere, our ambassador at Madrid, on 17th September 1804 revealed the unreality of this excuse; for he reported that Spain had previously decided to yield on that question. As the Spanish fleet was evidently preparing to cooperate with that of Napoleon, Pitt resolved to deal the blow which Chatham was not allowed to deliver in 1761. The weak point of Spain was her treasure fleet; there was an inner fitness in wrenching from her the gold which was soon to go into Napoleon's coffers.
On Tuesday, 18th September, the Cabinet assembled, Eldon, Camden, Hawkesbury, Melville, Mulgrave, and Pitt being present. In view of the news brought by Frere, and other tidings from Rear-Admiral Cochrane off Ferrol, Ministers decided to order Cochrane closely to blockade that port, preventing both French and Spanish ships from sailing out. Admiral Cornwallis, then blockading Brest, was to reinforce Cochrane, thereby assuring the capture of the Spanish treasure ships bound from South America to Cadiz.[695] Pitt at once reported this decision to Harrowby, then in attendance on the King at Weymouth, and urged a speedy ratification of it.[696] Hence without delay the order went forth which enlarged the area of strife. The four frigates despatched for the seizure of the treasure-ships were not so superior in force to the convoying corvettes as to avert a conflict. One of the Spanish ships blew up: the others surrendered (5th October 1804). Resenting this outrage, Spain declared war on 12th December.[697] Pitt did not consider the capture of the treasure-ships as necessarily involving war, but rather as a sharp warning, called for by the hostile conduct of Spain; for on 23rd September he wrote to Harrowby stating that they must wait for the Spanish answer to our ultimatum, and in the meantime Spanish merchantmen might leave British ports unmolested.[698]
The seizure of the Spanish treasure-ships caused resentment at St. Petersburg until the causes of Britain's action were more fully known. But the event did not long delay a good understanding. The prospect of Sicily falling a prey to the French army of occupation in South Italy alarmed both the Czar Alexander and Pitt. The former was bound by a Convention signed in 1798 to befriend the Neapolitan Court; and it was also to his interest to prevent France dominating the Mediterranean and expelling the Russians from Corfu. He therefore demanded from Napoleon the evacuation of Italy and North Germany, a suitable compensation for the King of Sardinia for the loss of his mainland possessions, and the recognition of the complete neutrality of the Germanic Empire. Far from complying with these demands, Napoleon kept his troops in South Italy and Hanover, and early in November seized Sir Horace Rumbold, British ambassador at Hamburg. At once Pitt and Harrowby made effective use of this incident to prove the impossibility of peace with Napoleon. The Russian and Prussian Courts sent sharp remonstrances to Paris; and, to humour Frederick William, Napoleon ordered the release of the envoy, though in the most grudging way possible. This violation of international law served to counterbalance our irregular action against Spain.
In short, Napoleon's evident resolve everywhere to carry matters with a high hand convinced the Czar that war was inevitable; and he prepared to espouse the cause of Britain, not so much from sympathy with her as from detestation of her restless adversary.[699] On 20th November Pitt wrote from Downing Street to Harrowby, who was then taking the waters at Bath, expressing joy that the views of Russia coincided entirely with ours, especially as to the reduction of the French Power within its ancient limits. He added these noteworthy words: "The restoration of the [French] monarchy may become in the course of events an object to be distinctly aimed at, but it certainly cannot be made a substantive object in the first instance; and it is very satisfactory to see that in this important point there is no apparent difference in our sentiments."[700] The hope of ending Prussia's subservience to Napoleon, and of inspiring Francis of Austria with a manly resolve, proved futile. Frederick William and Haugwitz hoped to creep into Hanover, under the French Emperor's cloak, and Austria had not yet suffered enough humiliation to lead her to fling down the gauntlet. True, she signed a compact with Russia on 6th November 1804; but it was timidly defensive in tone. Alexander therefore held back in the hope that events would compel her to take sides against Napoleon.
Far less calculating was Gustavus IV of Sweden. With the chivalrous zeal of his race he stood forth the first among the European monarchs as the declared ally of England. After the execution of the Duc d'Enghien by the French Emperor, he informed "Monsieur" Napoleon Bonaparte of the rupture of all relations between them; and now, on 3rd December 1804, an Anglo-Swedish Convention was signed, placing at our disposal the Isle of Rügen and the fortress of Stralsund in Swedish Pomerania, in return for a subsidy of £80,000. This sum served but to whet his appetite for subsidies, his demands almost equalling in extravagance his Quixotic summons to a royalist crusade.
Pitt therefore based his hopes on the statesmanlike policy of the Czar, who in that month despatched to London one of his confidants, a clever but viewy young man, of frank and engaging manners, Count Novossiltzoff. Ostensibly the mission was for scientific purposes; but French agents discovered that he took with him a plan of a Coalition against Napoleon.[701] This seems to have led the Emperor to take a step similar to that of Christmastide 1799. On 2nd January 1805 he wrote a letter direct to George III, proposing terms of peace. The King at once expressed to Pitt his astonishment that "the French usurper" had addressed him in this objectionable manner, and highly approved the draft of an answer which Pitt had thoughtfully forwarded to Windsor. In it Pitt declared that His Majesty could not enter upon the proposed overtures for peace until he had communicated them to the Powers with which he had confidential ties, especially to the Emperor of Russia. At the King's command, he sent a copy of this answer to St. Petersburg. At London, then, as also at Paris, Napoleon's offer was deemed a diplomatic device for getting news, though it also enabled him to represent himself as the friend of peace and Pitt as its worst enemy.
While the French Emperor played his game with the advantages conferred by a daring initiative, superior force, and unquestioned authority at home, Pitt had to employ all possible means to conciliate allies abroad and half-hearted friends at Westminster. His position was far from secure. True, the King had now recovered almost his usual health; but in Parliament the Ministry with difficulty repelled the bitter attacks of Fox, Sheridan, Grenville, and Windham. The speech of Grenville on the seizure of the Spanish treasure ships was of singular bitterness. Though aware of the provocations of the Spanish Court, he chose to represent that affair as a cowardly, and almost piratical attack on an unprepared Power. Pitt had expected some such misrepresentations. He knew that the Opposition would strain every nerve to overthrow him; and in the Christmas Vacation he made timely overtures through Hawkesbury for the support of Addington. The two old friends met on 23rd December 1804, at Hawkesbury's residence, Coombe Wood, near Richmond Park. The host contrived to be absent when Pitt entered the room, and he advanced with the cordial greeting: "I rejoice to take you by the hand again."
