Hawkwood honored his agreement with the Florentines not to make war in Tuscany, limiting himself to putting down the various rebellions within the papal states ; in 1377 Hawkwood abandoned Gregory XI entirely and joined the anti-papal coalition.

Gregory XI's other condottieri also limited their acitivities to Romagna, notably sacking Cesena in February 1377.

In the spring of 1377, papal mercenaries recaptured Bologna, which up until that point had been a key Florentine ally.
