Flouting a ban to return to Italy - info?

[john m roberts]

Supposedly the Roman survivors of Cannae were formed into two legions and sent to Sicily for garrison duty and were forbidden to return to Italy. The surviving soldiers of Fulvius Centumalus, also defeated by Hannibal, were sent to join them. These soldiers petitioned Marcellus to take them into his army that was about to besiege Syracuse. Marcellus asked the senate and was granted permission on the proviso that they were to receive no honors or rewards, no matter how well they fought. I don't believe they were ever allowed to return.
