for him by
Italian intriguers. He had already shown that he knew how to push his
own interests, by changing sides and taking service with the highest
bidder, as occasion prompted. Nor, though his character for probity
and loyalty stood exceptionally high among the men of his profession,
was he the slave to any questionable claims of honour or of duty. In
that age of confused politics and extinguished patriotism, there
was not indeed much scope for scrupulous honesty. But Filippo Maria
Visconti proved more than a match for him in craft. While Colleoni
was engaged in pacifying the revolted population of Bologna, the Duke
yielded to the suggestion of his parasites at Milan, who whispered
that the general was becoming dangerously powerful. He recalled him,
and threw him without trial into the dungeons of the Forni at Monza.
Here Colleoni remained a prisoner more than a year, until the
Duke's death in 1447, when he made his escape, and profited by the
disturbance of the Duchy to reacquire his lordships in the Bergamasque
territory. The true motive for his imprisonment remains still buried
in obscure conjecture. Probably it was not even known to the Visconti,
who acted on this, as on so many other occasions, by a mere spasm of
suspicious jealousy, for which he could have given no account.
From the year 1447 to the year 1455, it is difficult to follow
Colleoni's movements, or to trace his policy. First, we find
him employed by the Milanese Republic, during its brief space of
independence; then he is engaged by the Venetians, with a commission
for 1500 horse; next, he is in the service of Francesco Sforza; once
more in that of the Venetians, and yet again in that of the Duke of
Milan. His biographer relates with pride that, during this period,
he was three times successful against French troops in Piedmont and
Lombardy. It appears that he made short engagements, and changed his
paymasters according to convenience. But all this time he rose in
personal importance, acquired fresh lordships in the Bergamasque, and
accumulated wealth. He reached the highest point of his prosperity
in 1455, when the Republic of S. Mark elected him General-in-Chief of
their armies, with the fullest powers, and with a stipend of 100,000
florins. For nearly twenty-one years, until the day of his death, in
1475, Colleoni held this honourable and lucrative office. In his will
he charged the Signory of Venice that they should never again commit
