The British government was aware of the situation in Germany when it received a request in January, 1809, for the despatch of a British force to the mouth of the Elbe. Austria was, however, still nominally at war with Great Britain, and George III., perhaps not unreasonably, refused to give her active military assistance till peace was concluded. Meanwhile a subsidy of £250,000 in bullion was despatched to Trieste, and inquiries were set on foot as to the means of supplying such a military expedition as Austria desired.[38] On March 22, Dundas, who had only been a few days in office as commander-in-chief, reported that 15,000 men could not be spared from home service, and, in consequence, no extensive preparations were made until the muster rolls in June showed that 40,000 troops might safely be employed abroad. This convinced the government that a large force could be sent without interfering with home defence, as Castlereagh had long contended; and throughout June and July the naval and military departments were busy in preparing for what has since left a sinister memory as the Walcheren expedition. Meanwhile, as if the passion of frittering away resources were irresistible, a smaller force was despatched, as a kind of feint, against the kingdom of Naples. It consisted of 15,000 British troops and a body of Sicilians. Bailing from Palermo early in June it captured the islands of Ischia and Procida and the castle of Scylla, and threw Naples into consternation. But the attack was not pushed, and it was too late to be of any assistance to the Austrians who had already been expelled from the Italian peninsula. At last, in July, the treaty of peace with Austria was signed and the great armament was ready to sail.
