On land too the Byzantines were victorious: their troops managed to ambush the advancing Arab army under a commander named Mardasan and destroy it in the hills around Sophon, south of Nicomedia.
Di daratan juga Bizantium memperoleh kemenangan: pasukan mereka berhasil menyergap pasukan Arab yang sedang bergerak maju di bawah komando Mardasan dan menghancurkannya di perbukitan di sekitar Sophon, sebelah selatan Nikomedia.
