Must plead in order to get somewhere near Woolwich (9)

I believe the answer is:

plumstead

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

'get somewhere near woolwich' is the definition.
I don't know anything about this answer so I can't tell whether it can be defined by this definition.

'must plead in order' is the wordplay.
'in order' is an anagram indicator (the letters in a new order).
'must'+'plead'='mustplead'
'mustplead' is an anagram of 'PLUMSTEAD'.

'to' acts as a link.

Can you help me to learn more?
