Curtis established smaller supply " forts" along Tne Wire Road , I know one at Lebenon and one at Marshfield with others south of Springfield for his Pea Ridge Campaign.Perhaps, by following the MSM all the way down to the southwest corner of the state, Lyon outran his line of supply, which was at Rolla, a 100 miles away over a poor wagon road. He could've, perhaps should have withdrawn closer to Rolls and await for more supplies and troops. Perhaps a more prudent General would have done so. But there was no "stopping" or prudence in Lyon's character; he wanted to punish those Missourians who refused to bow to the authority of the Fed. Government. And loosing the battle of Wilson's Creek and the death of Lyon didn't change the fact that the Union controlled the MO river for the balance of the war with all of the consequences I listed in my original post.
