When first informed of Murat's treason by the Viceroy the Emperor refused
to believe it. "No," he exclaimed to those about him, "it cannot be!
Murat, to whom I have given my sister! Murat, to whom I have given a
throne! Eugene must be misinformed. It is impossible that Murat has
declared himself against me!" It was, however, not only possible but
true. Gradually throwing aside the dissimulation beneath which he had
concealed his designs, Murat seemed inclined to renew the policy of Italy
during the fifteenth and sixteenth centuries, when the art of deceiving
was deemed by the Italian Governments the most sublime effort of genius.
Without any declaration of war, Murat ordered the Neapolitan General who
occupied Rome to assume the supreme command in the Roman States, and to
take possession of the country. General Miollis, who commanded the
French troops in Rome, could only throw himself, with his handful of men,
into the Castle of St. Angelo, the famous mole of Adrian, in which was
long preserved the treasury of Sixtus V. The French General soon found
himself blockaded by the Neapolitan troops, who also blockaded Civita
Vecchia and Ancona.


The treaty concluded between Murat and Austria was definitively signed on
the 11th of January 1814. As soon as he was informed of it the Viceroy,
certain that he should soon have to engage with the Neapolitans, was
obliged to renounce the preservation of the line of the Adige, the
Neapolitan army being in the rear of his right wing. He accordingly
ordered a retrograde movement to the other side of the Mincio, where his
army was cantoned. In this position Prince Eugene, on the 8th of
February, had to engage with the Austrians, who had come up with him, and
the victory of the Mincio arrested, for some time, the invasion of the
Austrian army and its junction with the Neapolitan troops.
