@Marathan on southshore just about everyone escaped, considering how fenris island is FULL of survivors, to the point that on this quest and this quest shows just how many of them left, wich is pretty much the whole damn town.
on Silverpine, there were no children, or inocents. That was a war front. The alliance invaded horde lands, and the horde repelled them, simple as that. Mess with the bull and you get the horns.
there were no "inocents or childrens" of the alliance on gilneas simply because at the moment of the horde invasion, Gilneas was NOT a part of the alliance. I should remind you that their jerkass leader said this gem of a quote to Terenas shorly after the second war was over:
Damn the orcs, damn the Alliance, and damn you! The last thing Gilneas needs is sponges from other nations drawing from our resources, Dalaran wizards meddling with our affairs, and someone else's enemies killing our soldiers! Gilneas is its own nation and it always will be. This is the last time I'll ever talk to you, Terenas, so I hope you were listening
(Taken from Genn's article on wowpedia)
so this was simply the horde attacking a nation with a considerable military presence, and a rather dangerous enemy of the forsaken (worgens have been a threat to the forsakens for the past 6 years) rather than them attacking a nation of the alliance. The gilneans rejoined the aliance AFTER this invasion.
on New Andorhal there were no children either. The alliance and horde were trying to conquer the zone and they had only military presence there to push the other away. This was simple combat, where soldier fought soldier, that's war and in war there are casualties. Its not the same as attacking a civilian town full of non-combatants.
on ashenvale theres silverwing refuge, wich was the main base of operation of the sentinels, again another military target, as oposed to a civilian outpost.
on the broken front, indeed that was very dishonorable ( I hate that quest) but again those were soldiers, not civilians, and the commanding officer (Sky-reaver Krom) was chewed out by Garrosh and the Warchief, as well as demoted of his command after the northrend campaign.
Stonetalon was also dishonorable but the druids in the grove were neutral (there were tauren druids as well as night elven ones) and even then, the guy responsible was harsly punished (with his life)
wich leads us back to: Taurajo
A civilian town, with children, and lots of non-combatants. Primarily a hunter's camp, full of (duh) hunters that brought food and natural resourses to the rest of the tauren tribes. Attacked cowardly at night, with siege tanks, drunk wildhammer griphon riders (Don't question me on the "Drunk" part, this quest shows that wildhammers love to fight dead-drunk) and ex-convicts, during the night, while the hunters were out, and the only people in the town were civilians who coudn't fight back.
king's honor my ass.
