To be fair you have to be impressed by Westmoor, they haven't fallen into any of the traps set and have effectively maintained their economy while being targeted by a goliath. It's almost guerrilla warfare, they know the lands and terrain and just keep coming back it would seem.
Sirion made a rule that they would never attack a city(e.g. Oligarch) and actually haven't been doing as well so far as looting is concerned. From all friendly reports, enemy reports, and scout reports, I think it is fairly easy to say Webin is not a very good General though. Pity.
