Castruccio considered that he ought not to hesitate to render the emperor this service, because he believed that he himself would not be safe if at any time the emperor ceased to hold Rome.

Leaving Pagolo Guinigi in command at Lucca, Castruccio set out for Rome with six hundred horsemen, where he was received by Enrico with the greatest distinction.

In a short time the presence of Castruccio obtained such respect for the emperor that, without bloodshed or violence, good order was restored, chiefly by reason of Castruccio having sent by sea from the country round Pisa large quantities of corn, and thus removed the source of the trouble.
When he had chastised some of the Roman leaders, and admonished others, voluntary obedience was rendered to Enrico.

Castruccio received many honours, and was made a Roman senator.

This dignity was assumed with the greatest pomp, Castruccio being clothed in a brocaded toga, which had the following words embroidered on its front: "I am what God wills." Whilst on the back was: "What God desires shall be." During this time the Florentines, who were much enraged that Castruccio should have seized Pistoia during the truce, considered how they could tempt the city to rebel, to do which they thought would not be difficult in his absence.
