Makeshift camp (7)
I believe the answer is:
bivouac
'makeshift camp' is the definition.
(I've seen this before)
This is the entire clue.
(Other definitions for bivouac that I've seen before include "A temporary army camp" , "Temporary and basic encampment" , "Pass the night in the open air" , "Temporary camp without tents or cover" , "Encamp" .)
