The great civil war of North America was fought mostly in the forest, and often the men were not aware of the presence of one another until they came face to face.
They were almost at the bottom where the valley opened out in grass land, and were turning northward when Harry saw two figures ahead of them among the trees.

They were men in blue uniforms with rifles in their hands, and they were staring in surprise at the advancing columns in gray.

But their surprise lasted only a moment.

Then they lifted their rifles, fired straight at the Invincibles, and with warning shouts darted among the trees toward their own troops.
"Forward, lads!" shouted Colonel Talbot.

"We're within four hundred yards of the fort, and we must rush it! Officers, to your places!" Their own bugle sang stirring music, and the men gathered themselves for the forward rush.
