Thus Maria Theresa found herself standing alone in Europe, supported by England only, which indeed supplied her willingly with subsidies, but still directed its chief efforts to persuading her to purchase Frederick's friendship by the cession of Silesia. In accordance with the convention with Prussia, in August 1741, two French armies were poured across the Rhine, one passing through Swabia to assist the Elector in a direct advance on Vienna, the second through Westphalia. So little was England prepared for war, that the King, as Elector of Hanover, was obliged to declare the neutrality of his Continental dominions for a year, a step which excited great anger in England, where the war spirit ran high, and which was a fresh source of complaint against Walpole. At this crisis of her danger Maria Theresa found assistance in that part of her dominions where she had least right to expect it. The hand of the Hapsburgs had been heavy upon Hungary, yet thither she betook herself, and yielding back to them almost the whole of their constitution, excited the warlike magnates to enthusiasm by confiding to their charge her person and that of her child. As they crowded round to kiss the infant's hand, the hall rang with the shouts, "We will die for our king, Maria Theresa!" A moment's breathing space would allow time to bring the levée en masse of Hungary into the field: the opportunity was afforded by the diplomacy of England, which induced Frederick, who saw with jealousy the advancing power of France and Germany, to check his victorious march and sign a secret treaty at Kleinschnellendorf. The gathering forces of Hungary, the withdrawal of Frederick, and the errors of the Elector and of the French, who were jealous of each other, changed the face of the war. The march to Vienna was postponed for the capture of Prague. The withdrawal of the invaders to Bohemia allowed the Austrians to make a counter blow. As the Elector Charles Albert hastened to Frankfort to secure his election as Emperor, Khevenhüller, with the Austrian troops, was approaching his capital of Munich. Again, at the earnest entreaties of France, Frederick deserted his late engagements and renewed the war, but, unable to hold his advanced position at Olmutz in Moravia, he too fell back upon Bohemia, where the war was now centred.
