When the neighbours in question are the proud empires of Klatch and Ankh-Morpork, those are going to be some pretty large garden tools indeed. Of course, no-one would dream of starting a war without a perfectly good reason...such as a 'strategic' piece of old rock in the middle of nowhere.

It is after all every citizen's right to bear arms to defend their own. Even if it isn't technically their own. And even if they don't have much in the way of actual weaponry. As two armies march, Commander Vimes of Ankh-Morpork City Watch faces unpleasant foes who are out to get him... and that's just the people on his side. The enemy might be even worse.
