From a military standpoint, what is the result of the first encounter, in "The Red Badge of Courage"?

From a military view, the Union soldiers managed to hold off the Confederates. Henry ran from the battle, but a sufficient amount of soldiers held their positions. The soldiers that remained were able to repel the opposing forces, and so ensured a victory for the Union. Henry is very embarassed about running from the battle, and also scared that he will be branded as a deserter, and so tries to hide the fact that he was absent when the battle took place. From an overall military standpoint though, the Union forces won.
