A Hero’s Ascension

Dac sat in his tribe’s camp chewing on a piece of dried meat and staring out at the peacefully falling snow. He had always liked watching the snow, it made everything seem peaceful. He knew that the bloodshed to come would change all that.
A man in his tribe’s colors, which Dac couldn’t recognize rode on horseback though the camp yelling: “break camp! We march in one hour!” Dac was already ready: He liked to spend the time mentally calming himself. He needed to be able to think. He mounted his horse and headed towards the edge of the camp.

Soon they were heading towards the battle field that they and the other tribe had decided on. Dac absentmindedly thumbed the pommel of his sword, as he always did on the final march into a battle. Even though he was terrified of the fight coming he refused to think about it. He had seen men drive themselves insane waiting a mere hour before something like this.

I perceive serious trouble with commas. See Strunk & White (online) to fix this.

You repeat peacefully-peaceul, and already-ready; sounds a little funny.

A man in his tribe's colors, which Dac couldn't recognize -- sounds like Dac can't recognize the colors.

Not much physical detail except that it's snowy. Flat terrain? Forest? It would make a difference, and a bit more physical detail would help.

More major: I suggest more concrete sensory detail, to make it seem more real.
