I believe the answer is:

khartoum

I'm a little stuck... Click here to teach me more about this clue!

'where gordon fell' is the definition.
(I've seen this before)

I cannot understand how the rest of the clue works.

(Other definitions for khartoum that I've seen before include "General Gordon died at the siege of this African city" , "foreign city" , "Capital of Sudan" , "where Gordon fell" , "Nile location" .)

I've seen this clue in The Telegraph.
