The song "Back To Back" by HammerFall describes a battle between warriors who ride into the morning mist armed with swords, ready for battle.

As they engage in battle, the sound of metal clanging fills the air, and the warriors fight fiercely to achieve victory. The song describes how the soldiers of eternity are unstoppable, and their swords spin around as they slay their enemies. However, the lyrics also acknowledge that the warriors are not invincible. As night falls, and the light disappears, the warriors realize the danger they are in, and they are lost in the chase. Overall, "Back To Back" is a powerful song about the strength and courage of warriors who never give up. It speaks to the power of determination and the fight for justice, even in the face of overwhelming odds.
