The Normans at the Glykys river began to starve, while horses & men suffered epidemics; losses were very heavy

Summary:
[First discussed out of chronological order by Anna Komnene.] The army of Robert Guiscard was camped by the river Glykys, but was blockaded by enemy ships on the sea and harried by troops from Dyrrachion on land, so that they and their horses began to starve, further distressed by the weather and consequent disease. Losses were extremely heavy, at all levels of the army
