Such were the difficulties which Ministers had to contend with for commencing the war at sea. In one particular, however, there was more liberality; money was ungrudgingly voted; the land-tax was raised from two to four shillings in the pound, and the Sinking Fund was so freely resorted to, that the supplies altogether amounted to upwards of four millions. During these discussions, news came on the 13th of March, that on the 21st of November, 1739, Admiral Vernon had taken Porto Bello from the Spaniards. This was good news for the Opposition, for Vernon was one of their party, and a personal enemy of Walpole. There were great rejoicings and the Lords sent down an address of congratulation to the king, for the concurrence of the Commons. Yet in this they could not avoid making a party matter of it, the address stating that this glorious action had been performed with only six ships, and thus to mark the contrast with the doings of Admiral Hosier in those seas, and so to blacken his memory. The address was carried in a thin House, but only by thirty-six against thirty-one, so that along with the news went the comment to Vernon, that the Ministry begrudged him his glory. Parliament was prorogued on the 29th of April, 1740, and the king set off on his summer visit to Hanover. [Illustration: GREAT SEAL OF GEORGE II.] The turn of affairs on the Continent justified Walpole's gravest apprehensions. France was discovered to have made a compact with Spain, and once having taken this step, she displayed her usual activity in every Court of Europe, to induce the allies to break with England and prevent her from making new leagues. Walpole did his best to counteract these French influences. He managed to secure the Russian Court, before in connection with France, and subsidised Sweden, Denmark, Hesse-Cassel, and some other of the German States. But at this crisis (1740) died the savage old Frederick William of Prussia, and his son Frederick now commenced that extraordinary military career which obtained him the name of the Great. Temptingly adjoining his own territory, the young king beheld that of an equally young female sovereign, Maria Theresa of Austria, and he determined to extend his kingdom at her expense. The mystery of Frederick's movements was dissipated by his crossing, on the 23rd of December, the Austrian frontiers into Silesia. It was seen that it was the favourable opportunity of overpowering a weak neighbour which had tempted the Prussian to break his engagement, and to endeavour to make himself master of the domains of a defenceless young princess. But Frederick brought out some antiquated claims on the province Of Silesia, and on these he justified his breach of treaties. Maria Theresa applied, in her alarm, to the Powers who had concurred in the Pragmatic Sanction, but all except George II. fell away instantly from her. They believed her incapable of defending her territories, and hoped to come in for a share of the spoil.
