The Gonon-u-Kazgûmhoth was the Supreme Commander of Dol Guldur, sometimes mistaken for the Necromancer himself.
While the Gonon-u-Kazgûmhoth would be the high commander of Dol Guldur and major general of three Urhoth or 12.000-30.000 Soldiers, in the Military of Gorgoroth the Gonon was more similar to to a General or Lieutenant General and in charge of ten or more Urhoth or 80.000-126.000 Soldiers.
