The act or place where something (like troops or a river) emerges from a confined space into an open area.
From French 'débouchement', the noun form of 'déboucher'. Used primarily in military and geographical contexts since the 1700s to describe strategic military positions and water movement.
The term comes up constantly in historical military accounts because generals knew that controlling a mountain pass's 'debouchment' was like controlling a bottleneck—one well-placed force could hold off thousands. It's why castles were built at river debouchments.
