 Meanwhile, at Carpentras near Avignon, Clement was unwilling to fully support Henry, since Robert, of a cadet line of the French, was the representative of French power in Italy, and Clement was far from independent of French policies, as well as considerations about encirclement by Henry should he successfully defeat Robert.But before Henry could move against Robert of Naples, he had to deal with the troublesome Florentines, who had been sending money to the Lombard cities that held out against Henry, and who had been strengthening the city’s fortifications in anticipation of a siege.In mid September, Henry approached the city and very quickly, it was obvious that the city militia and the Guelph cavalry could not match the emperor in an open battle against his battle-hardened soldiers from the north.
