re: #339 Jimmah

It’s effectiveness was not so much in the physical structure itself, as the demeanour of the people standing immediately behind it :D

Indeed.

And given the military capabilities of the time, a wall was a most efficacious deterrent.

Manpower was cheap, so guarding it was not a problem until the Teutons on the Continent grew so obstreperous that the legions had to be redeployed.

If ravening hordes of Angles and Saxons ever head for Scotland to steal all the sheep, Hadrian’s Wall will still be a major asset to the defenders. Turn about is fair play.
