 When the German army of 20,000 men arrived in Byzantine territory, Emperor Manuel I Komnenos feared they were going to attack him, and had Byzantine troops posted to ensure against trouble.A brief skirmish with some of the more unruly Germans occurred near Philippopolis and in Adrianople, where the Byzantine general Prosouch fought with Conrad's nephew, the future emperor Frederick I Barbarossa.To make matters worse, some of the German soldiers were killed in a flood at the beginning of September.
