This song tells the story of a battle in olden times over a buried treasure. Both sides kill for it, willing to smite their neighbors for the promise of riches. After the battle, the victors find that under the stone covering what they think is the treasure is just the words "Peace on Earth."
The song's message is that human greed and violence is futile - a "tin soldier" is a miniature toy soldier, representing the inhuman aspect of the pursuit.
