In army dining hall he comes together (6)

I believe the answer is:

meshes

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

'comes together' is the definition.
(I've seen this in another clue)

'in army dining hall he' is the wordplay.
I cannot really see how this works, but
'he' is found in the answer.
'dining hall' could be 'mess' (I've seen this in another clue) and 'mess' is found in the leftover letters.
No letters remain.
This explanation may well be incorrect...

Can you help me to learn more?

(Other definitions for meshes that I've seen before include "gets engaged" , "Engages with others - using nets?" , "Co-ordinates" , "Fits into, intertwines" , "Becomes entangled or fits together" .)
