Quest:The Alliance Needs Iron Bars!

Objectives
Bring 20 Iron Bars to Corporal Carnes at the Military Ward in Ironforge.
 * Iron Bar x20

Description
Well hello there,  Fancypants, aren't you a sight for sore eyes. In case you hadn't heard while you were out there "adventuring", the Alliance has been gearing up for a war in Ahn'Qiraj and is in need of iron bars... a whole mess of 'em. Bring them to me in stacks of twenty. We can count on you, right, ?

Rewards
You will receive: Alliance Commendation Signet x10 and Ahn'Qiraj War Effort Supplies

Progress
If you have those twenty bars of iron, I don't want to know where you have them hidden!

Completion
Well, well, if it isn't. And you pulled through. I guess now I'll have to keep my eye on you. It hurts me to say this, but thanks for your efforts. The Alliance won't forget, and neither will I. Now get out there and bust your hump on whatever else needs collecting.
