hey mel i think this is the song you are talking about!

Impi

Chorus:
Impi! wo 'nans' impi iyeza
Obani bengathinta amabhubesi?


All along the river Chelmsford's army lay asleep
Come to crush the Children of Mageba
Come to exact the Realm's price for peace
And in the morning as they saddled up to ride
Their eyes shone with the fire and the steel
The General told them of the task that lay ahead
To bring the People of the Sky to heel

Chorus

Mud and sweat on polished leather
Warm rain seeping to the bone
They rode through the season's wet weather
Straining for a glimpse of the foe
Hopeless battalion destined to die
Broken by the Benders of Kings
Vainglorious General and Victorian pride
Would cost him and eight hundred men their lives

Chorus

They came to the side of the mountain
Scouts rode out to spy the land
Even as the Realm's soldiers lay resting
Mageba's forces were at hand
And by the evening the vultures were wheeling
Above the ruins where the fallen lay
An ancient song as old as the ashes
Echoed as Mageba's warriors marched away

Chorus
