Oh, have you gone to the battlefield is a song known by Justice of Toren One Esk.

The lyrics are as follows:

Oh, have you gone to the battlefield
Armored and well-armed?
And shall dreadful events
Force you to drop your weapons?

These are strikingly similar to an old christian spiritual, Clamanda:

Oh have you ventured to the field,
Well armed with helmet, sword, and shield?
And shall the world, with dread alarms,
Compel you now to ground your arms?
