[William Cloud Hicklin]

There exists at Marquette a full accounting of the Nazguls' movements from the attack on Osgiliath in June until the defeat at the Fords- it is this (with the Nazgul identified by letters A through I) which is excerpted in Unfinished Tales, and also in the Reader's companion (alas, with the identifying letters edited out). I might be able to see this published in full some day.

Unfortunately Tolkien made no such accounting for the War of the Ring- his notes refer to "a Nazgul," ''four Nazgul;" but aside from the WK none is identified, nor does he tell us if, for example, Khamul or some other was present for the attacks in the North.
