Of course, they couldn’t control the waterway itself, so their worst nightmare right now was a ship sinking in the channel right between the gates. Vessels large and small had been moving through in both directions during the hours since the notice had gone out. It was hard to miss the military and police deployment on land, sea, and air, keeping many eyes on every vessel that moved between the gates and making sure they kept moving. Tugboats were standing by to push or pull anything that got in the way.
