I protest against this version
point one: My Tengu commanders disobey my orders. So basicaly, it doesn't matter whatever strategy I gave you, you simply didn't use it.
My strategy was to drop the heavy stones unto the roofes of the fort, from such a height, they should have enough force behind them to damage it somewhat.
Another important point of my strategy was that the attack was launched AT NIGHT
again a point you completely ignored. The chance of being hit by any ranged weapon, at such a great distance, AT NIGHT, when your shots are more or less good guesses, well, do the math. Even assuming the steamguns have scatter shots, did you ever go hunting with a shotgun ? At a range of 200 meters, scatter shots are pointless, as the shrapnel is now so inaccurate that you would only slightly injure your target. I dare you to kill something on 200 meter with a shotgun.
If the steam guns were just one-shots, the same applies as to the bows.
200 meter at NIGHT. Seriously, try and hit something at such a geart distance, in nothing but a faint moonlight (assuming that there were no clouds).
Also, why are there warehouses destroyed, and why are there fires in the city ?
The Tengu were dropping heavy stones on the roof of the fort.
My whole strategy was completely ignored by you, I will not accept that.
point 2.
Longbows do have a reach over 200 meters, true.
Ever seen a bowman shoot at distance ? Yep, they shoot in an arc.
They shoot into the sky at an angle, so that the target get's hit from above.
A shot at a distance of 200 meters is only possible when the target is on the ground. A 200 meter shot straight into the sky is impossible. And even if it was, the Valtan have no experience at shooting at flying targets at an angle, because this time it was much higher than the hight the Tengu normaly attack.
A similar point goes for the steam gun. Even if there is great force behind the shot, at 200 meters vertical height (if you add the horizontal distance, it would be much more than 200 by the way) the shot would no longer by flying completely straight. A shot that is VERY hard to aim. On a moving target. AT NIGHT (god damn, how could you ignore the fact that the attack was launched at NIGHT)
point 3.
Lightning ?
Well, if this was divine intervention by Nhipanter, fine with me, but a god with the spheres: cunning, battle, ingenuity, knowledge, the forge, would not be able to throw lightning at my men. If it was lightning by a thunder storm, then
point 2 applies much more than before. Wind, rain, and (as opposed to moonlight) almost complete darkness.
If this lightning was artifical, I challenge that by the fact that
a) the valtans producing a functional lightning trap within just about 5 months of research and having it be so sucessful that it only hit the Tengu when they came in for a sneak attack, and not, say, whatever other birds like seagulls or whatever are flying around the area, oh COME on.
b) if it wasn't a trap and the lightning was cast activly, then there is still the point that no one knew they were coming, because it was NIGHT
